In an anti-locking hydraulic brake system comprising a master brake cylinder (1) connected by conduit (4) to at least one wheel brake (5), an intermediate accumulator (9) connected by a return conduit (7) to the wheel brake (5), inlet and outlet valves (6, 7) in the respective conduits (4, 7) and a pump (10) for delivering pressure fluid from the intermediate accumulator (9) to the wheel brake (5) above the inlet valve (6), a throttle (27) is provided in an intake conduit (11) between the intermediate accumulator (9) and the pump (10) which acts to reduce pedal pulsation during braking slip control. A valve (29) in parallel with the throttle is opened when the accumulator is filled so as to supply the conduit (4) while the pump has not yet attained its full discharge capacity after being switched on. A valve (40) is switched over for traction slip control and supplies the fluid from the master cylinder reservoir (2) to the pump intake downstream of the throttle. <IMAGE>
