An electrohydraulic vehicle brake system includes an electromechanical actuator for actuating at least one hydraulic piston to build hydraulic pressure at wheel brakes. The brake system provides a set of electrically activatable valve arrangements having a first valve arrangement between a cylinder accommodating the at least one hydraulic piston and each of the wheel brakes, and at least one second valve arrangement between a receptacle device for hydraulic fluid and at least one of the wheel brakes. The second valve arrangement is provided in parallel with the first valve arrangement which is associated with the same wheel brake as the second valve arrangement. A control device or system activates the first valve arrangements and the electromechanical actuator, in order to build up a hydraulic pressure at at least one of the wheel brakes and via the opened first valve arrangement associated with that wheel brake and to reduce a built-up hydraulic pressure via the opened first valve arrangement. The activation of the first valve arrangements can take place in a time multiplex operation.
