A method for decreasing brake-pressure of an electronically slip-controllable power braking system (ESPBS) and an ESPBS. The wheel-brake pressure is generated by electronic activation of a drive motor (DM) of a pressure generator (PG) (external force). The driver indicates braking intention by actuating a master brake cylinder, which is set indirectly by a control unit via electronic activation of the DM. Plunger devices (PDs) include a plunger piston (PP), accommodated moveably in a plunger cylinder (PC). Driven by the DM, PP and PC execute a translational movement in relation to one another. A pressure buildup/decrease is performable in a BC connected to the PD as a function of movement direction. To avoid pressure medium contaminated with gas entering the BC undetected during pressure decrease after cancellation of the intention, actuation of the PD in the pressure-decrease direction is performed until the BC pressure has dropped to a pre-determinable threshold and ended.
