ABSTRACT:
A brake heat gauge for use with a vehicle with a plurality of wheels each with at least one brake shoe adapted to frictionally engage an associated brake drum upon the braking of the vehicle. The present invention includes a plurality of heat sensors each mounted on a corresponding brake shoe and adapted to transmit via the transmission wire a temperature signal representative of a temperature of the brake shoe. Also provided is a control panel situated within a cab of the vehicle which includes a temperature meter for visually indicating a temperature represented by a temperature signal upon the receipt thereof, a light emitting diode digital display adapted to display a number, a warning light adapted to emit light upon the actuation thereof, and an audible alarm adapted to transmit a sound upon the actuation thereof. Finally, a controller is connected via the transmission wires between the heat sensors of each of the wheels and the temperature meter, digital display, warning light, and audible alarm. In use, the controller is adapted to display on the temperature meter the temperature corresponding to the highest temperature measured by the heat sensors and further depict on the digital display a number corresponding to the wheel whose associated heat sensor measured the highest temperature.
