Abstract
This invention related to a multi-layered damped anchor shim adapted for use in a drum brake assembly. The anchor shim includes an inner surface and an outer surface which is adapted to contact the second ends of the brake shoes. The anchor shim includes a damping material applied to the inner surface thereof so as to be disposed between adjacent contacting areas of the outer surface of the inner retainer plate and the inner surface of the anchor shim to thereby reduce the transmission of noise from the brake shoes through the abutment assembly to the backing plate.
