An electronically pressure-controllable vehicle braking system and a method for controlling an electronically pressure-controllable vehicle braking system are described. Such vehicle braking systems may stabilize a vehicle, assist the actuation of the vehicle braking system, and/or enable a fully automated or semi-automated driving operation. For this purpose, the vehicle braking systems include a primary actuator system which sets or regulates different braking pressures at the wheel brakes and furthermore includes an electronically controllable secondary actuator system which protects the vehicle braking system against, inter alia, failure of the primary actuator system. According to the invention, in the event of a fault in the primary actuator system, an activation of the secondary actuator system takes place in such a way that the secondary actuator system generates a braking pressure which, taking into account the dynamic axle load displacement in the direction of the front axle taking place during a braking operation, is greater than the braking pressure convertible into a braking power by the wheel brakes on the rear axle. A provided unit reduces this braking pressure at the at least one wheel brake of the rear axle to a value at which the wheel of the motor vehicle assigned to the at least one wheel brake of the rear axle does not lock.
