Motor vehicle brake detector
First Claim
1. A motor vehicle brake detector comprising a blind hole formed in a brake shoe of a motor vehicle brake assembly, a thermo sensor packed by an insulator fastened inside said blind hole and connected to a warning control circuit for permitting said warning control circuit to give warning signals as said brake assembly was overheated during a brake or said brake shoe of said brake assembly was worn off;
- said thermo sensor including a metal sleeve connected to one end of said warning control circuit by a first conductor, and a thermo resistor received inside said metal sleeve and having an output terminal extended outwardly and welded to said metal sleeve and an input terminal connected to an opposite end of said warning control circuit by a second conductor; and
said warning control circuit including an indicator lamp electrically connected with said thermo resistor in series in between said first and said second conductors of said thermo resistor, whereby upon increasing of temperature of said brake assembly, said thermo resistor will decrease its resistance and increase its negative voltage to thereby increase a light intensity of said indicator lamp for warning purpose.

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.
