Wear indicator with deformable lips for disc brake - is held within recess in brake lining support plate by pressure of expanded lips upon walls

摘要

A recess (1) in the plate (2) carrying the friction lining (3) accepts a pin (7) of electrically insulating material in which a wire (8) is embedded. The pin (7) protrudes from a fixing element (4) on which two diametrically opposed lips (5, 6) have rounded ends (13, 14) bearing upon the walls (9, 10) of the recess (1). To install or withdraw the pin (7), it is necessary only to pinch the lips (5, 6) together so that the element (4) can pass through the opening between edges (11, 12). ADVANTAGE - Insert is held firmly within brake lining without risk of loosening by heat generated in braking.
