ABSTRACT:
A disc brake assembly comprises an anchor bracket (12), a brake shoe (10) which carries a friction lining (16), the shoe being slidably supported by the anchor bracket (12). The assembly includes a retraction mechanism which is adapted to retract the shoe from the disc when the brake is released. The mechanism comprises at least one pin (24) secured to either a backing plate (14) or the anchor bracket and a spring clip (26) fixed relative to the pin which acts between the pin and the other one of the anchor bracket or the backing plate. Deformation of the spring clip as the shoe is moved towards the disc providing a returning force to pull the friction lining away from the disc when the brake is released.
