Abstract

A method and a device for check-testing a braking system in which, before travel commences, a self-test of the braking system is performed. During the course of the self-test, the valve arrangements allocated to the wheel brakes and the pressure supply providing the brake pressure are driven in a predefined manner. A plurality of test phases are provided, after whose respective conclusions, a pressure level to be expected should be reached. Otherwise a secondary braking operation is initiated at least for the subsequent operating cycle of the vehicle.
