Damped pad spring for use in a disc brake assembly

Abstract

This invention related to a multi-layered damped pad spring adapted for use in a disc brake assembly. The disc brake assembly includes an anchor bracket adapted to be secured to a vehicle component, a brake caliper adapted to be secured to the anchor bracket, a pair of friction pads carried by the disc brake assembly and adapted to be disposed on opposite axial sides of an associated brake rotor, and actuation means for selectively moving the friction pads into frictional engagement with the rotor. The pad spring is carried by the disc brake assembly and is disposed between the anchor bracket and at least one end of one of the pair of friction pads. In a preferred embodiment, the pad spring is a multi-layered pad spring and includes an outer layer disposed adjacent the friction pad and in contact with at least a portion thereof, and an inner layer disposed adjacent the anchor bracket and in contact with at least a portion thereof. The outer layer is formed from a first material and the inner layer formed from a second material. Preferably, the first material is metal and the second material is a damping material which covers the entire inner surface of the metal outer layer and is applied thereto prior to the forming of the pad spring by a stamping operation.
