  • Patent number: 4771387
    Abstract: A method and apparatus for testing motor vehicle anti-skid braking systems is disclosed which is particularly well suited for production line verification of the anti-skid braking system integrity. The method comprises monitoring the operation of a pressure generating device which operates intermittently to generate brake actuating pressure independently of application of the vehicle brake pedal while simultaneously and cyclically applying a predetermined operating force to the vehicle brake pedal and measuring the distance of travel thereof for each successive operation. The first phase of the test procedure enables verification of the operation of the pressure generating device and associated controls therefor whereas the second phase of the test sequence verifies the absence of fluid or pressure leakage in another portion of the braking system.
