Abstract
In a hydraulic vehicle braking systems operable via hydraulic external energy from a pump or, in the event the pump malfunctions, via hydraulic energy made available using a master brake cylinder via muscle-powered energy, provision is made for safe braking via muscle-powered energy such that at least one cylinder-piston configuration isolates at least two wheel brakes from the hydraulic pressure medium that is able to be pumped by the pump. The hydraulic vehicle-braking system incorporates wheel brakes of one axle that is isolated from a hydraulic pump in terms of pressure medium by a cylinder-piston configuration, which wheel brakes are supplied with pressure medium by one master cylinder chamber of a master brake cylinder. The other master brake cylinder chamber is allocated to the two other wheel brakes of the other vehicle axle, so that given bubble-free pressure medium downstream from the pump, the wheel brakes of both vehicle axles make a contribution to vehicle deceleration.
