A check valve is connected in parallel to each inlet valve. At the start of a wheel-individual brake pressure control, all inlet valves are closed, and a pressure build-up is carried out in a predetermined group of one or more wheel brakes by displacing a pressure medium volume into the predetermined group of wheel brakes by the pressure supply device.

A solenoid drive circuit includes a control circuit 2 which comprises a detector 6 with a resistor 6a for discerning current flow therethrough to produce electric signals that correspond to level of current flow through a solenoid 4 connected to the resistor 6a; an amplifier 7 for amplifying the electric signals from the resistor 6a; and an integrator 8 for integrating the amplified output from the amplifier 7. As integrator 8 is reset each time a PWM controller 3 generates at least one of the successive drive signals S3, an operational comparator 5 receives the latest updated and integrated values S8 of relatively small amount from the integrator 8, easily and promptly compares the updated values S8 from the integrator 8 and an objective current values to produce a deviation of the integrated values S8 from the objective current value, and provides the PWM controller 3 with a command value S5 indicative of the deviation. As the PWM controller 3 provides the control terminal of a MOSFET 10 with the drive signals S3 of pulse width which corresponds to the command value S5 from the operational comparator 5, the current flow through the solenoid 4 can be controlled for accurate activation of the solenoid 4 in good responsiveness to current flow values through the solenoid 4.
