Abstract
A vehicle brake system may include: two hydraulic brake circuits, each having at least one hydraulically operating wheel brake; first and second pressure supply devices; at least one valve assembly for adjusting the brake pressure for each wheel individually and/or for separating/connecting the wheel brakes from/to at least one of the pressure supply devices; at least one electronic control and regulating unit; and a hydraulic connection line connecting the two brake circuits. Each wheel brake is paired with a dedicated switch valve, and each brake circuit has a hydraulic main line via which the switch valves may be connected to the pressure supply devices. The connection line has two connection switch valves connected in series and open when unenergized via pressure present in the respective hydraulic main line and/or an inner section of a connection line connecting two connections of the connection switch valves directly together.
