Friction pad assemblies for disc brakes

Abstract

The present specification discloses a friction pad assembly and disc brake incorporating such an assembly, wherein the friction pad assembly comprises a backing plate and a pad of friction material secured thereto, a wire spring being secured to the backing plate. The wire spring comprises a coiled region from which two arms extend in generally opposite directions. The coiled region of the spring is located in a recess in the backing plate with the arms extending from the recess on opposite sides of the backing plate. Thus the spring arms are the only parts of the spring extraneous to the dimensions of the backing plate so that in a simple manner the optimum amount of design space for constructional strength, is available in a brake incorporating such a friction pad assembly. Also, by virtue of the spring arms extending one on each side of the backing plate, stable spring biassing of the friction pad assembly is achieved in the brake.
