ABSTRACT:
Wear warning elements are respectively provided in back plates of a pair of friction pads at the front side thereof with respect to a rotational direction of a disc rotor. A pad spring is disposed between the friction pads and a carrier. The pad spring includes a pair of spring portions. The spring portions are resiliently pressed against the wear warning elements to bias the friction pads away from the disc rotor, respectively. During a braking state, the friction pads are pressed against the disc rotor against the biasing force of the spring portions. When disengaging the friction pads from the disc rotor, the friction pads are moved by the biasing force of the spring portions of the pad spring, thereby enabling the friction pads to be reliably moved away from the disc rotor and preventing drag between the friction pads and the disc rotor.
