PCT No. PCT/EP90/01760 Sec. 371 Date Aug. 12, 1991 Sec. 102(e) Date Aug. 12, 1991 PCT Filed Oct. 18, 1990 PCT Pub. No. WO91/07299 PCT Pub. Date May 30, 1991.A dual-circuit brake system including a diagonal division is provided by the invention. The brakes of the driven wheels, on the one hand, through inlet valves are in communication with the brake pressure generator and, on the other hand, through intake valves, are in direct communication with a pressure source. Moreover, communication is established with a reservoir through the outlet valves. For brake slip control purposes, pairs of inlet and outlet valves are actuated, while for traction slip control purposes, pairs of intake and outlet valves are actuated; during a traction slip control, the inlet valves and separator valves in bypass conduits leading to the inlet valves are closed. This circuit configuration involves the advantage that the intake and inlet valves may be provided with different diaphragms that are adjusted to the respective control mode. Providing the separator valves in the bypass conduits insures that the inlet valves are now inserted into the brake conduits that the pressure build-up during a normal non-controlled deceleration operation is substantially undisturbed.
