A system applicable to motor vehicles having a master brake cylinder with a pressure fluid supply container and at least one pressure control valve assembly is associated with a wheel brake. A pump provided which in the anti-skid mode pumps pressure fluid drawn from the wheel brake to the master brake cylinder by use of the pressure control valve assembly. In a traction control mode, the pump draws pressure fluid from the master brake cylinder and forces it to the wheel brake. To this end, the pressure control valve assembly has a first line connection communicating with the master brake cylinder, a second line connection communicating with the wheel brake, and a third line connection through which quantities of pressure fluid flows in the anti-skid mode to reduce the wheel brake pressure. Both simple design and increased functional reliability of the system are attained by providing that in the traction control mode, the third line connection of the pressure control valve assembly communicates with a pressure outlet of the pump.
