A circuit configuration for a brake system including an anti-locking control system, wherein a balanced pressure course is attained in the rear wheel brakes through control according to the 'select-low' principle. The circuit configuration is furnished with a supplemental circuit (8) comparing the rotating pattern of the rear wheels during the control and, upon detection of a brake moment difference (.DELTA.M) causes a brake moment correction. This correction can be achieved, for example, by prolongating (T.sub.p, T'.sub.p) of the pressure build-up pulses controlling the rise in pressure in the wheel exhibiting a lower brake moment.

Circuit configuration for a brake system comprising an anti-locking

An anti-skid-controlled hydraulic brake system is described where the pressure medium, bled off from the wheel brakes for the purpose of pressure control, is replaced from a storage reservoir. The pressure medium will be delivered by a pump to the wheel brakes, and also into the master brake cylinder. As a result, during brake slip control, the volume requirements of the wheel brakes partially are met from the master brake cylinder. Directly involved is a pedal pulsation. So as to attenuate the pulsation, a throttling unit is inserted into the line between the pump and the master brake cylinder. A simple embodiment includes an orifice inserted between the pump and master brake cylinder.
