Abstract
A brake lining temperature and wear sensor having a plurality of serially connected wire loops and a resistive temperature sensor having a lower range of resistance than any one resistor mounted in a cavity formed in the brake lining where a plurality of resistors are connected one to each wire loop to be sequentially connected to a sensor circuit as the brake lining wears and breaks each wire loop. A control unit provides an electrical current to the sensor circuit and monitors the electrical potential across the plurality of wire loops and the resistive temperature sensor and then generating an output signal representing the temperature and wear of the brake lining. In an alternate embodiment, a capacitor is connected across the plurality of wire loops and a resistive temperature sensor with a large range of resistance is used to monitor the brake lining temperature. The electrical current is turned off and on to provide a noncontinuous measurement of first the temperature of the brake lining and then at a later time a measurement of the wear of the brake lining.
