Abstract
A brake pad assembly provided for a disc brake apparatus. The brake pad assembly comprises a backing plate having a flat inner face and a flat outer face oriented opposite to the inner face, a friction member fixed to the inner face of the backing plate, and an anti-squeal shim attached to the outer face of the backing plate. The anti-squeal shim includes a flat support plate attached to the outer face of the backing plate and a straight flat flange plate. The support plate of the anti-squeal shim has a peripheral edge including opposite outer and inner edges and opposite side edges. The flange plate is in the form of a flexible cantilever formed integrally with the support plate of the anti-squeal shim and extends away from one of the outer, inner and opposite side edges of the support plate of the anti-squeal shim.
