Brake pad shims? (Professionals recommend)

  • A brake pad shim installs between the brake pad backing plate and the brake caliper piston on the inboard side and the brake pad backing plate and the outer caliper fingers on the outboard side. In simple terms, a noise-reduction shim “decouples” the brake pad’s steel backing plate from the caliper.

Do brake pads need shims?

Not all brake pads come with shims as they aren’t required and function perfectly without needing them. This doesn’t require the use of disc brake lube, but you can still apply a thin coating on top of the brake backing plate. Lastly, there are also titanium brake pad shims which act as an improved thermal barrier.

What do shims on brake pads do?

Brake Pad Shims: Pad shims on everyday passenger cars help reduce noise by providing a barrier between the brake pad and the caliper. The shim prevents small vibrations that build up to annoying noises when the brakes are applied.

Do brake shims work?

Brake shims work much the same way to adjust otherwise normal brakes. On the most basic level, for many new vehicles with new brake parts, brake shims function as anti-rattle pads. They keep the pads and rotors from banging against each other or squealing.

Do new brake pads come with shims?

A lot of newer brake pads come with the shims already attached to them. So, if you are trying to replace your brake parts, there are brake kits available which contain both the pads and shims together.

What happens if you don’t grease brakes?

This lack of lubrication causes a few things to happen. First, because the brakes don’t contact the rotor properly, your brake pads can wear unevenly. Second, the slide pins may stick, causing the brake pad to continually contact the rotor, resulting in a buildup of heat, which wears your brake pads down faster.

What are the metal clips that come with brake pads?

Abutment clips reside on the caliper bracket lands on most vehicles. They create a uniform surface for the pads to make contact with. Some abutment clips include fingers that hold the pad in place.

Do I need to grease my brake pads?

Keeping the brakes on your car lubricated is crucial to ensure that they work properly. It is critical to make sure that brake caliper grease or lubricant is applied to the correct part of the brake; an incorrectly lubricated brake can cause it to stop working entirely.

What do anti rattle clips do?

What is an anti-rattle clip? surface for the brake pad to move against. The clips may also have spring tension arms to keep constant pressure against the brake pad backing plate.

Is brake grease the same as regular grease?

Brake lubricants are specially-formulated products that are not the same as ordinary chassis grease or even multi-purpose grease. The kind of grease that’s used to lube tie rod ends, ball joints and U-joints is not the same as the lubricants that are required for brake system components.

Brake pad shims

Shims for reducing brake pad noise come in a variety of designs. A brake pad shim is installed between the brake pad backing plate and the brake caliper piston on the inboard side of the brake caliper and between the brake pad backing plate and the outer caliper fingers on the outboard side of the brake caliper, as shown in the illustration. Quite simply, a noise-reduction shim ‘decouples’ the brake pad’s steel backing plate from the caliper, which helps to reduce noise. In order to prevent the transfer of vibration to the caliper, a noise-reduction shim is formed of a noise-dampening substance and has a certain design.

Single versus multiple layered noise reduction shims

A single layer noise-reduction shim is formed of a soft metal that has a high degree of damping capacity and is used to reduce noise in a single layer. When compared to single-layer shimming, a multi-layer shimming often consists of two thin outside metal plates and an inner elastomeric core, or an inner metal core with two outer sheets of noise-dampening material, respectively. In some instances, the design of the inboard shim may be different from the design of the outboard shim, and vice versa.

When it comes to noise reduction, multi-layered shims are significantly more effective than single-layer shims.

Brake Pad Shim attachment methods

It is constructed of a soft metal with a strong dampening capacity that is used to create a single-layer noise-reduction shim. The inner elastomeric core of a multi-layer shim is frequently surrounded by two thin outer metal plates, while the outside metal plates are surrounded by two sheets of noise-dampening material. When a shim is installed between two wheels, the design of the inboard shim may differ from the design of the outboard shim. Effective noise reduction in these situations depends on the right positioning of soundproofing.

Pressure sensitive adhesive

Depending on the model, some noise reduction shims are supplied separately from the brake pads and are attached to the brake pad backing plate using pressure sensitive glue. The adhesive’s function is to hold the shim in place solely during the installation process. As a result of the shim’s form and location in the caliper, normal brake heat will damage the pressure sensitive adhesive after a short length of time, requiring it to be held in place. A multi-layer brake pad shim with rubber layers on the outside and a metal core on the inside.

Tabs and holes

In some shim designs, tabs or holes are included into the backing plate of the brake pad, which serves to secure the shim in place. Shim for the brake pad with tabs and holes

Rivets

Other shims are meant to be permanently affixed to the brake pad’s backing plate during the pad production process, while others are designed to be removable.

As a result of this strategy, the shim will never migrate and will never be re-used in any manner. Brake pad shim with rivets

Brake Pad Shims can’t be reused

Noise reduction shims, like anti-rattle/abutmentclips, should never be used more than once in a single installation. Over the course of their useful life, the shims lose their capacity to dampen noise. It is possible that reusing previous noise reduction shims will result in a brake job that is noisy, vibrational, and unpleasant in nature (NVH). Separation and degradation of the brake pad shims. It is not possible to reuse brake pad shims. Damaged brake pad backing plate and rusted shim for the 2019 season Rick Muscoplat is a professional musician.

Brake Shims: Don’t Judge A Book By Its Cover

In contrast to other lubricants or pastes, a quality brake shim may prevent brake noise for the whole life of the brake work and will not dry up or get displaced with time. But keep in mind that if a shim is left in the box, it will not be able to perform its function. Brake shims are not intended to be decorative, but rather to be used to alter the spacing and distance between the friction material and the rotor. Shims, on the other hand, are a component that is attached to the friction pad backing plate and provides multipurpose noise control.

  • In contrast to other lubricants or pastes, a quality brake shim may prevent brake noise for the whole life of the brake work and will not dry up or get displaced with time.
  • The design of the shim is determined by the engineering of the vehicle and the sound profile.
  • The following is a shim design for an application that does not have the same difficulty as the one described above.
  • The noise has simply been ‘tuned’ to be outside the range of human hearing or decreased to the point that it does not reach the driver’s ears.
  • Humans are only capable of hearing a restricted spectrum of sounds.
  • When these vibrations move into the caliper and knuckle, where they are reduced to levels that are audible to humans, the driver becomes aware of a noise.
  • Engineering words for this are ‘force coupled excitation,’ which indicates that the components are linked together as a combined system that will vibrate at the natural frequency of the system in combined modes of vibration.

This is the ‘starting point’ for braking noise.

Shakers, which are used to dampen and minimize the transmission and amplitude of vibrational forces that cause the caliper, pad assembly, and associated structure to be excited, are used to do so.

This is done by the use of viscoelastic damping material within the layered architecture of the shim as well as the way of bonding to the pad assembly.

They are made from a variety of materials, including metals, viscoelastic polymers/bonding compounds, elastomeric rubbers, and fiberglass.

High-quality brake shims are often made from a high-quality metal or fibrous material as the starting point.

Using a controlled method, the elastomeric materials may be applied to the steel, ensuring that the precise depth is achieved.

Engineers ‘tune’ these layers to provide the greatest noise, vibration, and harshness (NVH) characteristics for a certain braking system noise fingerprint or signature.

Another type of brake shim may be a four-layer sandwich that floats while also insulates and lubricates the braking system.

The reason for this is that the pad/caliper assembly experiences complex and dynamic vibrational deformations as a result of the superposition of the combined system’s inherent frequency mode forms, which must be regulated by an appropriately connected insulator.

The use of this strategy to solve NVH difficulties has several drawbacks, which are as follows: Lubricants and pastes do not attenuate forces by providing more mass to the brake pad, as is the case with brake fluids and pastes.

Furthermore, lubricants do not act as an insulator against vibration and are inefficient at certain frequencies.

High-temperature brake oil that has been specially designed to resist the heat while also not causing damage to rubber seals or plastic bushings is available.

When it comes to brake pads and shims, the old adage ‘don’t judge a book by its cover’ holds true.

Unless you have access to a testing facility that can test the complete car, there is no way to determine whether one brake pad shim is superior to another in terms of noise or even cost.

Despite the fact that some brake pads and shims appear fantastic right out of the box, the engineering may not be appropriate for the application.

After the pads have been put in the car, take the opportunity to go for a test drive. Simply pushing the brake pedal and backing the car out of the bay will not assure that the brakes will be in good working order when the client picks up his or her vehicle.

Best Car Brake Pads: Buyer’s Guide

When looking for the finest automobile brake pads, there are a number of aspects to consider before making your purchase. You’ll want to determine which sort of brake pad is appropriate for your needs and then select a brake pad that is specifically designed for your vehicle. The brake pads you purchase must be specifically suited for the make, model, and year of your car. Alternatively, you may enter your vehicle’s details into the Amazon window that shows up and Amazon will tell you whether or not the brake pads are compatible with your car based on the description of the brake pads.

  • Drum brake pads were the first type of brake pad to be developed for use in automobiles.
  • When the brake pedal is depressed, components known as shoes are forced against the drum, causing the wheel to slow down and eventually stop.
  • The higher the temperature of the drums, the less friction they can generate, reducing the effectiveness of the pads in slowing the wheels.
  • Discs are a more contemporary alternative to drums in many situations.
  • This amount of pressure and friction on the rotors leads the wheels to cease turning, which in turn causes your automobile to come to a complete stop.
  • This implies that they can lose contact with the rotor at high temperatures, causing the car to start moving again.
  • This component has a direct relationship to the type of pad.

Their instruments will be equipped with disc pads in the front and drum pads in the back.

Essentially, you should be sure you are purchasing brake pads for the front or back of your automobile, since they may be different in size and shape.

Semi-metallic brake pads are composed of 30-60 percent metal, with organic or mineral components added for additional friction.

These brake pads also have a high service life span.

Ceramicpads, on the other hand, are formed of a ceramic substance that has been burned in a kiln to create them.

They are, on the other hand, less harsh on rotors, generate less brake dust, and operate more quietly.

Choose well-known brands that may be a bit more expensive, but will provide higher-quality brake pads that last longer and provide superior stopping force.

It is possible to learn how to change brake pads without having any prior automotive experience by following the instructions that come with them or watching YouTube videos on the subject.

If you want to save money by installing your own brake pads, search for a brake pad kit that contains all of the hardware you’ll need to complete the job.

How Brake Shims Work

Brake shims are the most effective instrument available to vehicle manufacturers in the fight against brake noise. Unless they are there, the separate components of the brake would generate a great deal of vibration and noise. This page provides an in-depth examination of brake shims, as well as instructions on how to install them.

How They Work

Shakers for brakes prevent and minimize the transfer of vibrational forces as well as their amplitude and frequency. This is accomplished by the use of dampening material that is glued to the pad assembly. Shims also contribute bulk to the brake, which can help to reduce vibrations in the pad and caliper when the brake is applied. Shims can operate as a thermal barrier, ensuring that the pad temperature remains uniform throughout the pad’s surface area, resulting in consistent braking torque.

Engineers fine-tune these layers in order to get the optimal noise, vibration, and harshness (NVH) characteristics for that specific brake system.

Shim Installation

Take the time to thoroughly inspect every brake pad or shim before installing it. Most high-quality rotors and brake pads already have the insulator attached to them. Three aspects of efficacy are ensured as a result of this. In the first place, it protects the technician from neglecting to complete the installation. First and foremost, a hot press may be used to properly cure the adhesives. Second and last, the maker can test the shim to ensure that it operates as intended. It is possible to drop the shim on a hard surface to test how effectively it absorbs vibrations if one has not previously been installed.

It is far easier to return opened but unused pads than it is to return used pads.

However, the sound the customer is hearing is a result of the complete braking system, which is why it’s critical to examine the entire brake system when diagnosing brake noise problems.

DIRECTIONAL BRAKE PADS

Take the time to inspect every brake pad or shim before installing it. Most high-quality rotors and brake pads come with the insulator already connected. As a result, there are three strategies to assure efficacy. The technician will not forget to install it because of this feature. Secondly, a hot press may be used to adequately cure the adhesives, and thirdly, the shim can be tested to ensure that it operates as intended by the manufacturer. It is possible to drop the shim on a hard surface to test how effectively it absorbs vibrations if one has not already been installed.

When a client complains of brake noise, it’s simple to attribute the problem to the brake pads. However, the sound the customer is hearing is a result of the complete braking system, which is why it’s crucial to examine the entire brake system when diagnosing brake noise problems.

1. Gather everything that you’ll need

Prepare yourself for the work by making certain that you have all of the necessary tools, replacement parts, and materials. This will almost certainly include the following items: Tools:

  • Prepare yourself for the work by making sure that you have all of the necessary tools, replacement parts, and materials. Most likely, the following items will be on the list: Tools:

Parts that can be replaced include: Materials:

  • Aerosol brake cleaner, blue and red thread locker, a glass jar, mechanic’s wire, nickel anti-seize, and 1/4 inch vinyl tubing are all needed. Pads for polishing
  • Synthetic high-temperature brake grease
  • Rust penetrant in the form of a spray

2. Remove the wheel

It’s usually a good idea to concentrate on one aspect of the project at a time. All of the clips, springs, and other components are clearly marked on the diagram, making it easy to locate them afterwards. While the tyre is still on the ground, the first step is to release the lug nuts on the wheel. To lift one side of the automobile, use a jack stand beneath the engine to provide more stability for the driver. Remove the wheel in its entirety.

3. Unbolt and remove the calliper

Remove the calliper retention bolts as well as the calliper bleeder screw from their positions. Lightly reseat the calliper bleeder screw until it is secure. Elevate the calliper away from the rotor and position it on top of the calliper bracket.

4. Retract the piston

Using the bleeder screw, attach one end of the drain tube to it and the other end to the bottom of a glass jar. Open the bleeder and drive the calliper piston back into the bore, allowing liquid to flow out of the system. Remove the drain tube and tighten the bleeder after you’re finished. Using mechanic’s wire, attach the calliper to the coil spring or strut so that it does not dangle while you are working on the brake. Note whether or not the calliper bracket bolts were coated with red or blue thread locker before removing them since you’ll need to recoat the threads with the same kind when reinstalling the calliper bracket after removing it.

5. Remove the rotor

Remove the rotor hold-down screw from the rotor. If you are having trouble removing it, first soak it in spray rust penetrant for at least 15 minutes before attempting to remove it. After the screw has been removed, pull the rotor away from the hub using your fingers.

6. Cleaning is important

Inadequate cleaning or installation processes are directly responsible for the majority of frequent brake problems, such as noise and vibration. Proper cleaning and installation entails the following:

  • Removing all of the rust from the calliper bracket
  • Using aerosol brake cleaner on the calliper bolts and inspecting them for corrosion (replacing any that are deteriorated)
  • And Changing the anti-rattle clips and any other worn brake components that have become worn
  • Lubricating bolts and putting on new rubber boot covers
  • Using a polishing pad on your drill to remove all rust and dirt from the wheel hub can make this process much simpler
  • Cleaning the new rotors and spraying them with brake cleaning aerosol are recommended as a preventative maintenance precaution. Using a stiff brush and hot soapy water to thoroughly clean and dry the item is advised.

7. Reassemble

Removing all of the rust from the calliper bracket; Using aerosol brake cleaner on the calliper bolts and inspecting them for corrosion (replacing any that have deteriorated); The anti-rattle clamps and any other worn brake components should be replaced. Bolts and rubber boots are being greased and installed. Using a polishing pad on your drill to remove all of the rust and dirt from the wheel hub makes this process much easier. To keep your brakes in good working order, clean your new rotors and spray them with brake cleaner.

8. Final tasks

To complete the installation, lower the vehicle until the tyre is slightly over the ground. Install a torque wrench and tighten the lug nuts in a star pattern, half the necessary torque (see your owner’s handbook for further information). Set the torque wrench to its maximum setting and tighten the lug nuts in the same star pattern as before. Reduce the height of your vehicle and remove the jack. Continue with the second brake on the same axle and repeat the process. It is advised that the brake pads for all wheels on the same axle be replaced at the same time if possible.

While the engine is turned off, push the brake pedal several times until it feels firm to the touch.

Then take a test drive at a modest speed to confirm that the brake pads are in working order. Finally, consult your owner’s handbook to see if there are any special methods for breaking in new brake pads for your car’s make and model that you should follow.

Brake Kit Installation Guide

To complete the installation, lower the vehicle until the tyre is barely over the ground. Install a torque wrench and tighten the lug nuts in a star pattern, half the necessary torque (see your owner’s handbook). Turn on the torque wrench to its maximum setting and tighten the lug nuts in a star pattern. Remove the jack from underneath your automobile. Continue with the second brake on the same axle and repeat the process once more. The replacement of brake pads for wheels on the same axle should always be done together, according to industry standards.

While the engine is turned off, push the brake pedal several times until it feels firm to the floor.

To conclude, consult your vehicle owner’s handbook to determine whether there are any special methods for breaking in new brake pads for your particular car’s make and model.

How To Install a PowerStop Brake Kit

Before you begin installing brake pads and rotors, make sure you have the necessary supplies and specific tools on hand:

  • Brake fluid (as indicated in the owner’s manual)
  • Brake component lube
  • A jack and jack stands rated for the vehicle’s weight
  • Wheel chocks
  • And a caliper piston compressor or C-clamp
  • A jack and jack stands rated for the cars weight

We also urge that you use protective eyewear and gloves throughout the installation.

Step 2:Check Brake Fluid

Make sure the car is in the park position and that it is on a hard, flat surface before continuing. After that, check the amount of braking fluid in the reservoir. A quarter to half of the braking fluid should be in the reservoir. During step 9, keep an eye on the fluid level since the caliper piston will be compressed.

Step 3:Lift Vehicle

If the rear wheels will remain on the ground, use the parking brake to keep them from rolling backwards, then remove the lug nuts on the wheels just enough to allow them to break free before attempting to raise the car. Jack stands should be used to raise and support the car, which should be done using the correct jacking points indicated by the manufacturer. Caution: Always use jack stands to support your vehicle. Never attempt to work on a car that is only kept in place by a hydraulic jack or other means.

Step 4:Remove The Wheel

Remove the lug nuts and the wheel from the vehicle. It is better to work on one wheel at a time, leaving the other side intact so that you have a reference point when you are finished. Placing the wheel/tire assembly under the vehicle, close to the nearest frame rail, suspension component, or crossmember is recommended as a safety measure. It is possible for the wheel/tire to prevent the car from collapsing if the jack stand is not functioning properly.

Step 5:Inspect Brakes

If there are any evidence of leakage or damage to the braking components after removing the wheel, replace the wheel.

Step 6:Remove Caliper

Remove the two caliper guide pin bolts that hold the caliper to the bracket and then remove the caliper from the bracket. Then, using a brake caliper hanger or a conventional wire coat hanger, support the caliper as it is being removed from the vehicle.

Precaution: Always keep the caliper supported. The caliper should never be allowed to dangle from the brake hose. This has the potential to cause damage to the brake hose.

Step 7:RemovePadsCaliper Bracket

Remove the two caliper guide pin bolts that hold the caliper to the bracket and then remove the caliper from its bracket. Then, using a brake caliper hanger or a conventional wire coat hanger, support the caliper as it is removed. Keep the caliper steady at all times. Never allow the brake caliper to dangle from the brake line while in operation. The brake hose may be damaged as a result.

Step 8:Remove the Rotor

It is now possible to remove the rotor. Before removing the rotor, make sure there are no holding screws present. Some cars employ retaining screws to secure the rotor to the hub, whereas others do not. These will have to be taken care of. Rust can cause the rotor to become stuck to the hub, and a mallet will be required to free it. Tap both the front and rear sides of the rotor, alternating left and right, top and bottom, left and right, top and bottom.

Step 9: Compress thePiston

Next, the piston is compressed back into the caliper, and the process is repeated once again. As the pad material wears away, the piston has grown in length. When installing new thicker pads, you must restore the piston to its original position within the caliper body to allow enough space for the bigger pads to be installed. Place a used brake pad over the face of the piston to prevent the surface from becoming marred, and begin compressing the piston with a piston compressor or a big C-clamp to prevent the surface from becoming marred.

Allow for a leisurely entry of the piston to avoid dangerous back pressure and damage to the ABS modulator, brake valving, or master cylinder.

Afterwards, release and remove the piston compressor or C-clamp that was previously utilized.

NOTE: Because many rear brake pistons screw in and out, a C-clamp will not be effective in retracting them.

Step 10:Clean the Rotor Hub

With a wire brush and a hub cleaning kit, remove any rust from the face of the hub mating surface and let it to dry. It is possible for rust or debris on the hub to produce rotor runout and thus generate wheel vibration. Apply a little layer of anti-seize on the hub’s face to prevent it from becoming stuck. The next time you remove the rotor, it will be much easier to do so. Check out this video for additional information on how to prepare the rotor hub for the installation of a brake kit:

Step 11:Clean the Rotor

With a wire brush and a hub cleaning kit, remove any rust from the face of the hub mating surface. Wheel vibration can be caused by rotor runout caused by corrosion or debris on the hub.

On the face of the hub, apply a thin layer of anti-seize. The next time you remove the rotor, it will be much easier to do. To learn more about how to properly prepare the rotor hub for the installation of a brake system, watch the video below:

Checking For Lateral Runout

When installing rotors, it is recommended that the lateral runout be checked. This will inform you whether or not there is any discrepancy between the rotor and the hub to which it is attached. It varies from.003′ to.005′ depending on the application, although the maximum permissible lateral runout is usually.003′. Always refer to the manufacturer’s requirements for each application when in doubt about something. If there is a variance, it is usually simple to repair by re-indexing the rotor one hole at a time until the problem is resolved.

If the rotor is not properly indexed, it is possible to have some vibration or pulsation concerns, which may result in damage to the rotors over time if left unattended.

Before removing the rotor from the hub, make a note of its position relative to the hub to ensure that it is reinstalled in the same location.

It is not feasible to re-index a rotor of this kind in this manner.

Step 12:Install New Hardware

We recommend that you examine the lateral runout of the rotors before installing them. This will tell you whether or not there is any variance between the rotor and the hub to which it is mounted, which is important information. It varies from.003′ to.005′ depending on the application, although the maximum allowed lateral runout is.003′. It is always advisable to consult the manufacturer’s requirements for any given application. It is usually simple to remedy a variance by re-indexing the rotor one hole at a time, even if the change is significant.

Vibration or pulsation difficulties may occur if the rotor is not properly indexed, which may result in rotor damage over time if left uncorrected.

Before removing the rotor from the hub, make a note of its location relative to the hub to ensure that it is reinstalled in the same position.

Re-indexing is not feasible with this particular rotor design.

Step 13: Install Caliper BracketBrake Pads

To install and tighten the brake caliper bracket bolts to the manufacturer’s requirements, use a caliper wrench. After that, replace the old pads with the new ones. Using a tiny quantity of brake fluid, apply it to the back of the pads where they come into touch with the caliper, as illustrated in the photo below: Precaution: Do not allow any brake lubricant to come into contact with the friction side of the brake pads.

Step 14: Install the calipe r

Install the brake caliper, taking care not to twist the brake line, and tighten the caliper bolts to the manufacturer’s requirements when it has been installed.

Step 15:Bleed the brakes

Bleed the brakes to ensure that all air has been removed from the braking system. Every time you change the brake pads and rotors, we recommend that you flush the brakes. Not all vehicles have the same process for bleeding the brakes. Always refer to the Factory Service Manual for the right technique while performing any repairs. NOTE: After bleeding the brakes, check sure the brake fluid reservoir is completely filled to the top of the filler neck line. It is important not to overfill the reservoir.

Step 16:Install the WheelLug Nuts

Install the wheel and lug nuts in their proper locations. Lower the car back down to the ground and tighten the lug nuts to the manufacturer’s prescribed torque until they are completely tight. Follow the tightening procedure shown in the illustration below, which is depending on the number of lug nuts used:

Step 17:Break-in Procedures

Depending on the PowerStop rotors that have been fitted, follow one of the two break-in processes listed below. IMPORTANT: The break-in procedure is crucial to ensuring consistent braking, quiet stopping, and trouble-free operation of the brake system.

Break in Procedure for Drilled/Slotted and Non-Coated rotors:

Complete five moderate to aggressive stops from 40 mph down to 10 mph in fast succession, without allowing the brakes to cool and without coming to a complete stop on the road. If you are forced to stop, complete the stop and either move the car into park or create enough space in front of the vehicle to enable the vehicle to roll slightly while you wait for the traffic signal to turn green again. Due to the high temperature of the rotors, maintaining pressure on the brake pedal will compel the brake pad to come into contact with the rotor, perhaps leaving an imprint on the rotor.

Continue to break in the brakes by making 5 mild stops from 35 mph to 5 mph in rapid succession without allowing the brakes to cool off.

As soon as this is completed, continue to drive the car for the longest amount of time feasible without overheating the brakes or coming to an abrupt halt (Try for about 5 minutes at moderate speed).

Once this is accomplished and the brakes have cooled to their usual working temperature, you can resume regular use of the brakes.

Break in Procedure for Evolution Coated Rotors:

Perform 30 decelerations from 30 mph to 5 mph when the installation is complete. 30 seconds should elapse between each deceleration to allow for cooling. As the brakes heat up, you should expect to notice a strong resin scent. If you are forced to stop, complete the stop and either move the car into park or create enough space in front of the vehicle to enable the vehicle to roll slightly while you wait for the traffic signal to turn green again. Due to the high temperature of the rotors, maintaining pressure on the brake pedal will compel the brake pad to come into contact with the rotor, perhaps leaving an imprint on the rotor.

Once this is accomplished and the brakes have cooled to their usual working temperature, you can resume regular use of the brakes. Never use water to cool your brakes, since this might cause harm to them. Additional Suggestions How-Tos!
