An electro-pneumatic hand brake system is for a vehicle with spring-loaded brakes. The system includes a pneumatic relay valve, a bistable solenoid valve for controlling the relay valve and a control unit for controlling the bistable solenoid valve. An outlet of the relay valve is connected to ports for the spring-loaded brakes. An inlet of the bistable solenoid valve is provided for connecting to a line carrying ventilation pressure. A self-retaining switching valve with a control input is provided before the inlet of the bistable solenoid valve. The self-retaining switching valve can be moved against the force of a restoring element from a blocking position into a flow-through position when there is sufficient pressure at its control input. An outlet of the self-retaining switching valve is connected to the inlet of the bistable solenoid valve.
