The contact face of the wheel hub must be undamaged, rust-free, clean, and metallically bright. To protect against corrosion, apply a thin coating of spay oil to the contact face then wipe off with a lint-free cloth.
Do not grease the surface of the wheel hub after cleaning!
- The grease could come into contact with the brake during rotation.
- The tightening torque of the rims could then no longer be ensured.
