Mercedes-Benz offers a reminder regarding brake disc service. It is imperative that when installing front or rear brake discs, any excessive corrosion/scaling which may have developed on the axle hub be removed.
Use the ATE Teves Hub Cleaning Kit to remove corrosion/scaling over the entire area where the brake disc mounts to the hub flange. Failure to keep the mating surface clean may cause an excessive build up which can cause adverse forces that may result in brake vibrations/judder.
