Abstract:
A drum brake assembly adapted to selectively frictionally engage a brake drum comprising:a backing plate supported relative to a vehicle component, said backing plate having at least one opening formed therethrough; at least one brake shoe supported on said backing plate for selective movement into frictional engagement with the brake drum, said brake shoe including a brake shoe sliding surface; a brake mechanism for selectively moving said brake shoe into frictional engagement with the brake drum; at least one damped brake shoe support device carried by said backing plate, said damped brake shoe support device including a first member and a second member, said first member being formed of a relatively rigid material and including a first end which defines a sliding surface for engagement with an adjacent surface of said brake shoe sliding surface, said second member being formed of a damping material and interposed between said first end of said first member and said backing plate, said damped brake shoe support device being carried by said backing plate for free play relative to said backing plate in at least one of a radial direction and an axial direction relative thereto.
