  • Patent number: 5302940
    Abstract: A motor vehicle brake detector is fastened in the brake shoe of a motor vehicle brake assembly and connected to a warning control circuit including a thermo resistor on the instrument board of the motor vehicle to give warning signals in terms of light intensity of an indicator lamp of the warning control circuit as the brake assembly was overheated during a brake or the brake shoe of the brake assembly was damaged to increase temperature of the thermo resistor and decrease the resistance of the thermo resistor, thereby increasing the light intensity of the indicator lamp for warning purpose.
