ABSTRACT:
A disc brake includes a rotor, an opposed pair of friction pads each arranged on an opposite side of the rotor, and a caliper which straddles the circumferential periphery of the rotor. The caliper has a pair of leg portions each arranged on an opposite side of the rotor. The caliper is arranged to push one of the friction pads against the rotor by a piston disposed within a cylinder formed in one leg portion and to push the other friction pad against the rotor on the other side with the other leg portion which is arranged to be slidable by a force of reaction to the thrusting action of the piston. A load distribution plate part is formed at the end of the piston which engages the back of the friction pad. This plate part on the piston is arranged to restrict rolling or turning of the piston around its axis by engaging the inner surface of a saddle portion of the caliper straddling the rotor.
