Absorbs vibrations during braking and suppresses squeals
- When braking, the “vibration” generated by the friction between the brake pad and disc rotor is transmitted to the piston inside the brake calliper, causing brake squeal. A “squeal-reducing shim” absorbs this “vibration” and suppresses the occurrence of squealing.

Note) Shims not designed for circuit use.
Please be sure to perform installation work at a certified repair shop/garage.
Mechanism of how noise occurs
- “Vibration” occurs when there is friction between the brake pad and disc rotor.
- When this vibration spreads to the piston inside the brake calliper and reaches an audible frequency, it produces an unpleasant squeal.
- By installing a shim, vibrations propagating to the piston are suppressed.
- Suppresses unpleasant squeals by lowering frequencies to inaudible levels.
*Squeal may also be caused by the material and wear of the brake pad/disc rotor, as well as the deterioration of parts other than the brake.
Please note that under these circumstances, the shim may not be able to suppress the noise.
Please see information about wear and squeal causes of brake pads and discs here.
Anti-squeal shim structure
- 3-layer structure absorbs and blocks pad vibrations
How to use “Anti-Squeal Shim”
If the installation method is inadequate, it may peel off or shift during use.
Please follow the steps below for installation.
- Thoroughly remove dirt and oil from the back of the brake pad (plate surface).
- Attach it so that there are no gaps according to the shape of the back of the brake pad.
- After pasting, apply grease as necessary.
- Attach the brake pads to the vehicle and check the operating condition of the brakes.
*Basically, do not use the stainless steel shims that come with the normal pad.
If you overlap them, they will become too thick and may not be able to be installed or may cause the brake pads to drag.
