A hydraulic brake system that has a hydraulic unit for evacuation prior to initial filling, with the primary and secondary circuits dry, the brake system is equipped with special check valves, which are disposed between the primary circuit and the secondary circuit. When the brake system is evacuated, these check valves are in the open position, so that air escapes from the secondary circuits. This makes it unnecessary to open electromagnet valves, which are closed when without current and are present in the brake circuits I and II, electrically. The hydraulic brake system is intended for use in motor vehicles, and its hydraulic unit is designed to carry out anti-lock operation and/or traction controls.
