Abstract
An anti-squeal shim comprises a metal plate and a compound layer applied to at least one side of the metal plate. The compound includes a nonmetal fiber other than asbestos, an elastomer, a filler and small pieces of cork. The anti-squeal shim is disposed between a forcing member that urges a friction pad against a disc rotor and a backing plate of the friction pad in a disc brake. Also disclosed is a disc brake where only one side of the metal plate of the anti-squeal shim is coated with the compound layer and the anti-squeal shim is opposed to the forcing member without intervention of a backing-up shim.
