PCT No. PCT/SE87/00521 Sec. 371 Date Sep. 7, 1988 Sec. 102(e) Date Sep. 7, 1988 PCT Filed Nov. 6, 1987 PCT Pub. No. WO88/03489 PCT Pub. Date May 19, 1988.The present invention relates to a brake control system for vehicles with hydraulic brakes, for preventing wheel blocking and/or spinning. The system is characterised in that the brake system is separable, by means of a valve (3), one for each wheel, into a primary circuit (4) and a secondary circuit (5). Sensors (6) are provided on each wheel for sensing the rotational speed thereof. A control device compares the speeds sensed by said sensor. In the event of a sensed abnormal condition (wheel blocking or spinning) of one or more wheels, the control device activates the respective valve. A pressure control system in the respective secondary circuit controls the pressure therein, independently of the pressure in the primary circuit, in order to cancel the abnormal condition of the corresponding wheel.
