    NOTE: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.
  2. Using the CH-41013  rotor resurfacing kit, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor (2).
  3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  4. Install the brake rotor (1) to the hub/axle flange.
