To install:


WARNING
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 run-out (LRO) of the brake rotor, which could lead to brake pulsation.

  1. Thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
  2.  
  3. Thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor.
  4.  
  5. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  6.  
  7. Install the rotor. Slowly turn the rotor while pushing the rotor towards the axle.
  8.  
  9. Install the caliper and the mounting bracket as an assembly.
  10.
