ABSTRACT:
The present specification discloses a disc brake and a friction pad assembly therefor. In the brake at least one pin passes through an aperture in the backing plate of the inboard friction pad assembly to form a friction pad guide and support. A sheath of corrosion-resistant material also passes through said aperture and is preferably an interference fit therein. The sheath extends towards the plane in which the disc engaging face of the friction pad secured to the backing plate, lies, and always covers the end region of the extended portion of the pin, the sheath being contacted and abraded by the disc of the brake as the pad wears. The sheath thus protects the pin from corrosion ensuring smooth movement of the friction pad assembly.
