Brake Shim Installation

BRAKE NOISE AND HEAT INSULATOR

RB brake shims are exclusively designed, developed and manufactured by TPM Products, Inc. (RacingBrake’s parent company) aiming to alleviate the squeaky noise that can arise under low speed and light braking. These shims are made of a high strength steel plate and coated with high temperature silicon rubber. They have been proven to effectively eliminate or substantially reduce noise, in addition to shielding the caliper from heat transfer.

These brake shims are designed primarily for anti-squeaking but can also shield the heat. They are made of high strength spring steel coated with high temperature rubber.

It's normal for the caliper piston to seat (penetrate) into the steel plate and dislocating the rubber coating (stuck to pistons) especially under extreme heat application. As long as the rubber coating is not in contact with the caliper and remains in place the shims will function as it’s intended for abating the brake noise.

You may need to clean the rubber around the piston area and reinstall the shims.

Due to the temperature limit these shims are for street driving only and are not suitable for the track applications.

Please note the following:

  1. RB shims should be installed directly against the backing plate of the brake pad – Any shims that come with the pads (OE or aftermarket) or RB brake kits (stainless steel shim) must be removed.
     
  2. Brake pad size can vary slightly from different suppliers; you may have to adjust the clips to ensure a tight fit against the pad.
     
  3. The shim will add thickness to the brake pad (0.8mm or .030”); you may find its too tight to fit in, especially when rotors and pads are both new. If this is the case, try to install the shims after the pads and rotors have worn in.
     
  4. Due to the various materials of brake pads, especially on performance pads, total elimination of brake noise is sometimes not possible. However, the noise should be reduced to an acceptable level.
     
  5. RB brake shims should work immediately after installation. However depending on your brake set up, it may take a few days or weeks for the shims to become fully seated. If there is if too much wear on a rotor/pad, a second set of shims may be needed. In this case, clips should be removed.

Brake (anti-squeak) grease or other agents are not recommended in combination use with RB shims as we have tried all of these and have found that they can generate ill effects.
