Реферат: The inside of the brake shoe is fitted with a special monitor (130) fitted through the mounting plate and providing a sensor head (162) recessed in a hole in the brake pad. The sensor head has a wire loop (164) linked to a pad wear indicator circuit to operate an alarm when the wire is cut. The brake drum is earthed and as the pad wear exposes the wire it provided an initial signal, before the wear progresses and cuts the wire. This provides ample warning that the pads are nearing the replacement state. The initial alarm could be a flashing indicator lamp while a constant lamp indicates a cut wire loop.
