Abstract
An aircraft brake includes a stack of rotors and stators located between a backing plate and a pressure plate. A brake thermal sensor includes a probe carried by the backing plate generating a signal representing the temperature of a backing plate friction pad. A temperature indicator connected to the probe is actuated by the probe signal to monitor the temperature of the friction pad. The probe includes a heat conductor which conducts heat from the friction pad to a temperature responsive device embedded in the heat conductor. The temperature responsive device generates the probe signal. A spring is biased to maintain the heat conductor in engagement with the friction pad so that the friction pad temperature is continuously monitored. A heat insulator limits the heat loss from the heat conductor.
