A brake pressure distribution between axles is regulated as a function of a difference in wheel rotational speeds between axles or wheel slip values between axles at the axles. Exceeding a predefined limit value in difference in the wheel rotational speed between axles or the wheel slip values between axles during braking serves to regulate the distribution. On the basis of the dependency between at least the brake pressure at the rear axle and the vehicle deceleration after at least two preceding service braking operations, a critical deceleration value is determined.
