A vehicle brake system having an anti-skid system with, at least one anti-skid valve assembly disposed in a brake line that leads from the master brake cylinder to the wheel brake. To pump pressure fluid out of the wheel brake to the master brake cylinder, a return feed line is provided. Located in the return feed line, in succession in the pumping direction following a pressure fluid reservoir, are a throttle and a return feed pump driven by an electric motor. In order to keep the feedback at the brake pedal slight during an anti-skid control event involving small quantities of pressure fluid to be returned, yet to make sufficiently large quantities of pressure fluid available in the master brake cylinder upon major brake pressure reduction, the following provisions are made: The pumping flow of the return pump can be increased with increasing pressure in the pressure fluid reservoir and/or upon attainment of a predetermined fill level in the pressure fluid reservoir and/or with an increasing volumetric flow of pressure fluid to be pumped back out of the wheel brake.
