Note: 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 mainly for street driving and may not be suitable for track applications.
RB brake shims (brake noise and heat insulator) are designed and manufactured to alleviate the squeaky noise that can arise under low speed and light braking. These shims are made of high strength steel plate and coated with high temperature silicon rubber and have proven to effectively eliminate or substantially reduce noise in addition to shielding heat transfer to the caliper. Brake Shim Installation:
- 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.
- Brake pad size can vary slightly from different suppliers; you may have to
adjust the clips to ensure a tight fit against the pad.
- The shim will add thickness to the brake pad (0.8mm or .030”); you may find
it’s too tight to fit in especially when both rotor and pad are new. If this is
the case try to install the shims after the pad/rotor have worn in.
- Due to the various materials of brake pads, especially on performance pads,
total elimination of brake noise is sometimes not possible. However, the noise
shall be reduced to an acceptable level.
- RB brake shims should work immediately after installation. However depending
on your brake set up, it may take a few days or weeks to become fully seated, or
if too much wear on rotor/pad a second set of shims may be needed (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 these and found out they can generate ill effects as you are experiencing.How RB brake shim was developed and manufactured:
TPM was the first manufacturer who has successfully developed a series of
brake shims for automotive aftermarket since 1987. Our objective was to
provide a solution to the brake industry in solving the brake squeaking
issue, which was a constant challenge facing the brake parts suppliers as
well as brake service companies.
This brake shim program was exclusively marketed by NAPD Inc. - A long term
partner of TPM in Mahwah New Jersey. The shims were initially tested,
approved and accepted by Midas International and followed by Meineke and
other major brake parts manufacturers such as; Wanger, Bendix, Raybestos (Aimco)
and national distributors such as; NAPA, AutoZone, CarQuest and Advance Auto
etc. under various trade names.
Our brake shim was recognized as the leader in the brake industry as it has
proven can effectively abate the noise as a result of our extensive research
and development on material and manufacturing process, however over the time
more replicas came out with low quality shims at cheaper price (black paint
instead of rubber coat).
With the success of our street brake shims our knowledge and experience in
design, material, testing production, and know how is well retained. We are
now one step further in developing shims for the performance division to be
the best noise and heat insulator.
