A slip-controlled brake system for all-wheel drive motor vehicles is provided with differentials (16,19,20) for balancing track difference between the individual wheels (VR, VL, HR, HL). Wheel sensors (31-34) and electrical circuits (9) for generating brake pressure control signals are provided to control the brake pressure in the event of imminent locking. A disconnecting clutch (37) is inserted into a driving split axle (25) connecting a wheel to the rear axle differential (20). The disconnecting clutch (37) can be actuated either electromagnetically or hydraulically. Upon commencement of the brake slip control or at a predetermined time thereafter, the disconnecting clutch (37) is disengaged thereby rendering the coupling between the rear wheels and/or between front and rear axles ineffective thereby to permit an individual slip control by way of the individual control channels.
