Abstract
A hydraulic brake system for a vehicle includes a master brake cylinder, a hydraulic unit, and multiple wheel brakes. The hydraulic unit Ha at least one brake circuit for modulating the braking pressure in the wheel brakes. At least one wheel brake is paired with a bistable solenoid valve, which is looped into the corresponding fluid channel directly upstream of the paired wheel brake and which enables the braking pressure in the paired wheel brake to be modulated in a de-energized open position and locks the current braking pressure in the paired wheel brake in a de-energized closed position, wherein a volume equalization device which comprises a connectable accumulator opens into the corresponding fluid channel between the bistable solenoid valve and the paired wheel brake.
