1. Use a suitable brake parts cleaner.
Please Note: Carburettor cleaner and brake cleaner products are not the same. “Carby” cleaner is intended to leave a lubricating residue whereas brake clean will leave a dry surface.
2. Apply the brake part cleaner to a clean cloth or paper towel.
Applying directly onto the disc rotor can damage any paint coating intended to protect the rotor from corrosion.
3. Wipe in a circular motion around the friction ring surface.
