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.

In an aircraft multi-disk brake assembly having an inboard end and an outboard end, including a brake housing at the inboard end and a brake stack at the outboard end comprising a pressure plate, and stationary members to provide braking to rotatable members when subjected to a pressure force by an actuating means on said pressure plate and the position of said pressure plate varying with the degree of wear of said brake stack; and indicator for sensing and indicating both the temperature and the degree of wear of said brake stack comprising: a housing, disposed within said brake housing, defining a bore having an axis positioned substantially perpendicular to said pressure plate; a biasing means, disposed within said housing bore; an axially movable probe member disposed within said housing bore, operatively engaging said biasing means for reciprocal movement therein and having inboard and outboard ends extending outside of said housing bore; said outboard end positioned in contact with said pressure plate by said biasing means; a thermocouple, disposed within said outboard end and secured in thermal conductive engagement therein; said inboard end being marked with a plurality of indicia for indicating the degree of brake wear; and wherein upon activation of said brake stack said probe member moves axially, maintaining contact with said pressure plate at the outboard end for monitoring the temperature of said brake stack and for determining the degree of wear of said brake stack by the distance traveled by said inboard end.
