Device for checking the leaktightness of a double-circuit braking system of a motor vehicle with result information

摘要

The aim of the device for checking the leaktightness is to warn the driver of the vehicle in the case of a lack of leaktightness in the brake circuit. It comprises a cylinder (1) with a piston (2) which is freely mounted. The cylinder (1) is connected to the two symmetrical brake circuits which make it possible to compare the precisions of the two brake circuits. The result of this comparison is indicated in front of the driver by signalling lamps (10). <IMAGE>
