1. Process for carrying out a load-dependent brake regulation of brakes on a commercial vehicle equipped with an electrically acting anti-lock system having an electronic central control and ABS brake valves adjacent the axle of the vehicle and possessing rotational-speed transmitters assigned to each brakeable wheel for providing instantaneous whee speed for an ABS control;

  • providing a load dependent regulation that is effective at a wheel brake pressure near a locking limit of the brakes; and

    automatically regulating mid-axle brake-pressure distribution solely according to wheel-speed signals supplied by the rotational-speed transmitters, in a slip range below a range in which the ABS function takes effect;

    wherein the automatic regulation of the brake-pressure distribution only occurs upon exceeding of a first predeterminable brake value in response to a correctable difference between mid-axle wheel speeds during braking.
