Abstract
This specification discloses a friction pad assembly for use in a disc brake. The friction pad assembly has a pad anti-rattle spring having a coiled region intermediate its ends, the coils of said coiled region being axially spaced apart from each other and engaging in a slot in the backing plate, the slot and spring presenting planar surfaces which can interengage with each other. Thus, by virtue of the interengaging planar surfaces the coiled region can only, at most, rotate to a limited degree in the slot and thus, should one spring arm be broken, the planar surfaces prevent the coiled region from rotating within the slot when a force is applied to the other arm whereby that other spring arm can continue to function. Also, the location of the coiled region in the slot is space saving and the spaced apart coils allows the maximum spring performance to be achieved.
