Bosch QuietCast Premium raises aftermarket brake pad technology to a whole new level. Employing the industry's best pre-attached, rubber core shims and Molded Shim Technology (on selected applications), QuietCast delivers the quiet operation you and your customers expect with the durability and long life that are the hallmarks of all Bosch products. Every Bosch QuietCast Disc Brake Pad is fitted with the industry's best pre-attached rubber core shim. This shim style is the most predominant type used by OE manufacturers and is exclusively offered by Bosch for the independent aftermarket.
At the time of pressing, heat, adhesive and pressure mold the multi-layer shim to the backing plate and friction material creating an integrally molded unit.
Shim stays attached throughout the life of the pad; won't walk or slide on the backing plate
Provides maximum stability resulting in quieter shim performance over the life of the pad
