It is imperative that when installing brake discs (front or rear) that any excessive corrosion/scaling which may have developed on the axle hub be removed (see Fig. 1). Use the “ATE Teves Hub Cleaning Kit” to remove the corrosion/scaling over the entire area where the brake disc mounts to the hub flange.
Failure to remove the corrosion/scaling may cause an excessive buildup, which can create adverse forces that may result in brake vibrations or judder.
