Abstract
A disc brake includes a carrier with a pair of axially and outwardly extending arms. A pair of pad springs are mounted to the inner side of the arms. Each of the pad springs has a pair of return springs. The return springs extend radially of a rotor and have respective projections. Each of the return spring is made by bending an elongated tongue. A pair of backing plates are attached to a corresponding pair of friction pads and have lugs. A wear warning element is attached adjacent to the lug of each backing plate and has a bent portion. Each of the projections is resiliently in contact with the inner side of the bent portion so as to constantly urge the backing plate and the friction pad in a direction away from the rotor.
