METHOD FOR TESTING THE FUNCTIONAL CAPABILITY OF A HYDRAULIC VEHICLE BRAKING SYSTEM

For testing the functional capability of a hydraulic power vehicle braking system, a power brake pressure generator is switched on. The power brake pressure generator displaces brake fluid through the non-actuated master brake cylinder into a brake fluid reservoir, which is why no brake pressure is built up. A brake pressure build-up allows a “hidden defect” to be inferred, which has no impact during normal operation and is therefore not noticed.
