Abstract: A brake failure warning device including an electrically conductive leaf spring which is spaced apart from an arcuate portion of the brake shoe and has one end biased towards the shoe. Connected to the one end of the leaf spring is a conductive plate, also spaced apart from the shoe, and a pin extending from the plate through the shoe a predetermined distance into the brake lining. The other end of the leaf spring is connected to, but electrically insulated from, the shoe via a non-conductive block. The leaf spring is electrically connected to an ignition switch and an alarm indicator located on the dashboard of a vehicle. When the brake lining has worn beyond the extension of the pin, the biasing force of the leaf spring urges the plate into contact with the shoe, thereby closing a circuit when the ignition switch is turned on to provide a brake failure warning signal. In an alternative embodiment, the pin is also made of a conductive material so that a second or back-up circuit is made through contact between the pin and the brake drum when the ignition switch is turned on.

Abstract: A disc-brake pad has a wear indicator characterised in that the indicator is separate from the frictional material and is slid into position on the backing plate from one edge thereof. The advantage is that the wear indicator and the leads thereto do not occupy space behind the backing plate .
