Abstract
The present invention provides a friction pad assembly wherein an edge region of the backing plate has two recesses located symmetrically about a center line (11) of the assembly with a resilient leaf spring secured across each recess (13). In use, in a disc brake retaining pins engage against the springs to hold the assembly in position. This pad assembly design thus minimizes the required space by locating the resilient pad anti-rattle springs within the profile and sides of the backing plate, and by using the necessarily relatively short springs, the tendency for the springs (19) to be buckled or distorted, or affected by heat, is minimized.
