Abstract
An anti-squeal shim comprises a metal plate and a compound layer applied only to one face of the metal plate. The compound includes a nonmetal fiber other than asbestos, an elastomer and a filler. The thickness of the compound layer is determined to be from 200 to 800 micron. 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 with the metal plate opposed to the forcing member without the intervention of a backing-up shim and with the compound layer opposed to the backing plate.
