ABSTRACT:
An indicator for indicating a predetermined amount of wear of a brake lining comprises a brake lining support member operably connected to a brake actuator and supported thereby, a brake lining is fixedly attached to the brake lining support member and when actuated by the brake actuator frictionally engages a rotating member rotatably mounted on an axle which carries the brake actuator, an electrical contact is connected to an electrical circuit and is disposed on the brake lining support member and insulated therefrom by insulator, the electrical contact has a head portion which contacts the rotating member and the brake lining support member frictionally engages the rotating member and the brake lining is worn to a predetermined level to complete the electrical circuit to energize an indicator connected to the electrical circuit.
