A hydraulic brake system has: a force-pressure conversion element, which is in hydraulic connection with at least one wheel brake cylinder of at least one wheel; a volume-adaptation element in hydraulic connection with the at least one wheel brake and the force-pressure conversion element; and as an actuating unit for actuating the force-pressure conversion element, which actuating unit has an input element. The pressure in the at least one wheel brake cylinder is adjusted by operating the volume-adaptation unit and/or the actuating unit. For this purpose an actuating state of the input element is maintained by operating the actuating unit when the volume-adaptation unit is being operated.
