Before the introduction of brake fluid, a brake system has to be evacuated to allow complete venting. A non-return valve 18 is provided to permit evacuation of a return line 15 which is separated from a brake line 12 by normally closed, pressure-reducing solenoid valves 16, 17. A solenoid valve 17 and the non-return valve 18 are in parallel, and the two valves are integrated into a single valve unit 40, in which elements 54, 56 are parts of the solenoid valve, and ball 72 and seat 70 constitute the non-return valve.
