ABSTRACT:
A method for pre-filling a low-pressure storage device of a motor vehicle braking system, having a changeover valve, a hydraulic pump, an outlet valve, and a low-pressure storage device situated in a suction line of the hydraulic pump. The low-pressure storage device can be pre-filled in a particularly simple and low-noise manner if the actuation of the foot brake pedal is monitored using a sensor mechanism and, when there is an actuation, the changeover valve is closed in order to lock in the braking pressure acting on the wheel brake, and at least one of the outlet valves is opened in order to release the braking pressure into the low-pressure storage device.
