Abstract
A vehicle braking unit comprises an operating braking pressure inlet which receives an inlet braking pressure built up by a braking cylinder, and at least one operating brake pressure outlet at which an outlet braking pressure is provided for an operating brake modulator, which is upstream of the operating brake and provides anti-lock functionality. At least one connecting channel hydraulically connects the operating brake pressure inlet to the outlet. Brake fluid is supplied from a storage unit through the brake cylinder, the connecting channel and the operating brake modulator. The braking unit has a brake fluid inlet, through which the brake fluid is received from the storage unit, a brake fluid pump, by which the brake fluid is suctioned through the brake fluid inlet and a supply pressure is built up, and a valve unit that controls the outlet braking pressure and/or a parking brake release pressure by the supply pressure.
