For a vehicle brake system having a brake pedal, a brake booster, a master brake cylinder and an electronically regulatable brake unit arranged between the master brake cylinder and the wheel brakes by which the brake pressure in the wheel brakes can be adjusted independently of the preliminary pressure existing at the output of the master brake cylinder using an electronic control unit, the electronic control unit senses the course of a pedal operating value which is achieved by the brake booster. The pedal operating value is directly proportional to the pedal force applied by the driver by way of the brake pedal. When a predetermined threshold value of the pedal operating value has been reached, the brake pressure in the wheel brakes is generated such that, in the deceleration course, a raised deceleration gradient occurs in the case of a further rise of the pedal operating value in the sense of an increase of the brake booster ratio.
