Abstract: Venting a cylinder of a piston-cylinder unit of a power brake pressure generator of a hydraulic power brake system for a motor vehicle. A piston in the cylinder is displaced from a forward-displaced position back into a home position and subsequently forward again. When the piston is displaced back, a connection valve is closed so that the piston sucks brake fluid from a brake fluid container, the brake fluid flowing over a lip seal acting in the manner of a pressure relief valve as the first piston seal. During the forward stroke, the piston pushes brake fluid through the then open connection valve into the brake fluid container. Any air contained in the cylinder is pushed with the brake fluid from the cylinder and separates from the brake fluid in the brake fluid container.
