The invention relates to an electrohydraulic brake system, which comprises an electromechanical actuator for actuating at least one hydraulic piston in order to set a hydraulic pressure at one or more of a plurality of wheel brakes. The brake system also comprises a set of electrically controllable valve assemblies, which set comprises a respective first valve assembly between a cylinder accommodating the at least one hydraulic piston and each of the plurality of wheel brakes and at least one second valve assembly. The at least one second valve assembly is provided between an accommodating device for hydraulic fluid and at least one of the wheel brakes, wherein the at least one second valve assembly is provided in parallel with the first valve assembly associated with the same wheel brake as the at least one second valve assembly. The brake system also comprises a control device or control device system, which is designed to open one of the first valve assemblies and the second valve assembly connected parallel thereto in order to release a hydraulic pressure built up in the cylinder into the accommodating device via the two opened valve devices.
