Abstract: A method for controlling an electronically slip-controllable power braking system and a braking system. This power braking system has a brake circuit and a pressure generator including a plunger piston for applying a circuit pressure to the brake circuit. The plunger piston delimits a pressure chamber of the pressure generator and is drivable by an activatable drive unit into a forward or reverse movement. During its forward movement, pressure medium is displaced by the plunger piston out of the pressure chamber into the brake circuit, while during the reverse movement, pressure medium flows out of a reservoir of the power braking system via a flow path into the pressure chamber of the pressure generator. The speed of the reverse movement of the plunger piston is adapted by the electronic control unit so that cavitation at the pressure generator of the power braking system, is avoided or at least minimized.
