Abstract
A hydraulic vehicle brake system including a brake line for conducting a hydraulic pressure medium and a master cylinder attached to a non-pressurized storage vessel. A wheel brake has a first pressure modulation valve on the inlet side and a second pressure modulation valve and a low-pressure accumulator on the outlet side of the wheel brake. A pump is disposed on a return line downstream of the low-pressure accumulator for removing pressurizing medium from the low-pressure accumulator to regulate the brake pressure via the first pressure modulation valve and also via an isolation valve disposed in the brake line upstream of the first pressure modulation valve. An electromagnetically opening changeover valve is inserted in a pump suction line discharging into the return line between the master cylinder and the low-pressure accumulator. The pressure provided by the master cylinder can be fed to the low-pressure accumulator, bypassing the wheel brake.
