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.
