Abstract
In a hydraulic braking system operated by an external force, for vehicles, in particular motor vehicles, having a primary pressure source which is operated by external energy and provide brake pressure to the wheel brakes during normal operation, and which also has a foot-actuated auxiliary pressure source which supplies the wheel brakes with brake pressure during emergency operation, to increase the degree of safety, a special hydraulic circuit is provided wherein, during emergency operation, only comparatively few valves between the wheel brakes and a hydraulic reservoir have to be closed so as to be free of leakage, while operational safety is increased by the valves being connected in series.
