Abstract
Polymeric materials are disclosed which are suitable for application to one or more metal surfaces in disc brakes to eliminate brake squeak therefrom. The preferred polymer comprises a high molecular weight acrylic copolymer containing sites for crosslinking on the main polymer chain.
Claims4
A method for reducing squeak in disc brakes caused by contact between the metal surfaces of the friction pad and brake support comprising applying a high molecular weight, thermally stable polymer composition to at least one of said metal surfaces in an amount sufficient to eliminate squeak, said polymer composition comprising a high molecular weight acrylic copolymer containing at least about 50% of a C.sub.1 -C.sub.8 ester of acrylic acid and at least about 1% of a monomer providing crosslinkable sites on the main polymer chain.
