ABSTRACT:
An indicator for monitoring both the temperature and the degree of wear of a brake. Specifically this invention may be used with multi-disk brakes, especially aircraft brakes. Upon brake actuation, a pressure plate compresses stationary and rotating members to provide braking. A probe member moves with and in contact with the pressure plate. The degree of wear of the brake stack is determined by the relative distance traveled by the probe. The probe member may be marked with indicia for indicating the wear or remaining brake life. The probe member also has a thermocouple embedded within it, thereby providing temperature indication of the brake stack. Signals from the thermocouple may be transmitted for indication and/or processing. Furthermore, this invention provides for modification of existing wear pins by the attachment of a thermocouple assembly.
