Disc brake pad retention coil spring releasably held on pin - has coil and pin dias. chosen so that greater friction exists between coil and pin than between spring arms and brake housing

摘要

The retention spring (5) for a disc brake pad (3) consists of two outwardly extending spring arms (7,8) connected to at least one spring coil (10), the latter releasably fixing the spring to a pin (9). The coil and pin dias. are chosen so that, with the spring arms in position against the brake housing, the axial friction force holding the pin is considerably greater than that between the spring arms and their contact surfaces. USE/ADVANTAGE - Retention spring for brake disc pad is securely held and easily replaced.
