DISC BRAKE WITH PARTIAL LINING AND RETURN DEVICE

摘要

In a disc brake with a partial lining for motor vehicles, a floating saddle is guided in a sliding manner on a brake support by means of slide pins (26). Internal and external brake shoes are fitted also to slide in relation to the brake support and parallel to the slide pins. On at least one of the latter is provided a return device (50) with a spring (52), which is arranged around the pin as a component element of a friction-type connection between said pin and a bore which guides it. Said bore (24) has at the end from which the pin is inserted in the latter an enlargement (54) in which is housed the spring (52) with an axial pre-loading. The spring or an element cooperating with the latter is in contact with the external surface of the pin.
