 11. Unscrew the fixing bolts (point 9) using an open-end spanner, and remove the caliper from the motorcycle frame.
The liquid supply hose is detached from the caliper.
12. Complete detachment of the fluid supply pipe (point 4) from the caliper.
13. Keep the end of the supply pipe raised to prevent fluid leaks.
The disc braking surface is cleaned and the spacers are fitted.
14. Clean the braking surface (point 10) of the disc (point 11) with a degreaser, e.g. SE 47 solvent.
15. Position the new caliper on the motorcycle.

16. Replace the original screw (point 9) with ones from the kit provided.

17. If necessary, mount the spacers (point 12) provided in the kit.

18. Insert the screws (point 9) without tightening
The bleeder plug and a clear tube are connected to the caliper.
