A pressure-medium brake system with division into two or more brake circuits is proposed. A relay valve is incorporated into each brake circuit. Control medium and working medium of each relay valve are supplied by the same pressure-medium source. For each brake circuit a single valve is provided in a service brake valve, which additionally has an electrical supply, with which the actuation of all relay valves can be controlled. The pressure-medium brake system is perferably embodied as an air-brake system and is intended for utility vehicles, such as trucks and buses.

A pressure-medium brake system for vehicles having at least two brake circuits, each of said brake circuits having its own source of pressure-medium, and each having one relay valve, said brake circuits controlled by a multi-circuit service brake valve, said multi-circuit service brake valve being in a line extending to control chambers associated with each of said relay valves, said control chambers arranged to control a braking medium, characterized in that said sources of pressure medium supplies a control for each of said relay valves and a working medium for actuation of the brake circuit and further that an electrical supply means for additional control of said relay valves is provided at said multi-circuit service brake valve.
