Abstract
A disc brake pad assembly includes a wire mesh screen 6 between the friction pad backing plate 3 and a shim 5 to reduce squeal when the brake piston 10 applies pressure to the backing plate to urge the friction pad 2 against the disc 1. The squeal suppression may be enhanced by applying a lubricant to the wire mesh screen.
