The QuietCast Premium Disc Brake Pad program offers top quality, availability, competitive pricing and full coverage for all makes and models of Domestic, Asian and European automobiles, light trucks and SUVs.

The Science Behind the Silence

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.

The laminated rubber-core shim is heat and pressure cured between two layers of steel (see Figure 1, opposite page). This process ensures the highest quality bonding of the rubber to steel resulting in lower noise, increased strength, and corrosion resistance. Sound vibrations pass through the friction material and backing plate, but are dissipated by the unique rubber core in the shim for remarkable noise dampening.

About Molded Shim Technology (MST)

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. The shim stays attached throughout the life of the pad; it won’t walk or slide on the backing plate, providing maximum stability resulting in quieter shim performance over the life of the pad.
