1. A method for adjusting brake pressures on wheel brakes in a pneumatic brake system of a motor vehicle, the method comprising:
providing, in a normal braking mode and as a function of a driver's braking demand determined by a driver of the motor vehicle, brake pressures to the wheel brakes in the pneumatic brake system of the motor vehicle;
determining, during the normal braking mode, a pressure distribution ratio starting value between a front axle and a rear axle;
storing the pressure distribution ratio starting value in a memory;
adjusting, by a brake control unit in a pressure control mode, the brake pressures on the wheel brakes to implement a drive stability function and/or external braking demands,
wherein the adjusting includes adjusting an ideal pressure distribution ratio of brake pressures at wheel brakes of the front axle to brake pressures at wheel brakes of the rear axle according to a control function, the control function receiving, as input, the pressure distribution ratio starting value.
