Instructions for the replacement of the brake caliper

The illustrations are provided as a guide. Before starting, make sure the replacement parts are suitable for the make and model of vehicle.

After replacing the caliper, make sure the supply brake lines on the vehicle are not twisted or excessively bent, as this would obstruct the passage of fluid. If necessary, replace the brake lines with more suitable ones.
During all the phases described below, ensure that the brake fluid does not come into contact with the vehicle painted parts. In the event of splashes or leaks of the fluid, immediately stop the leak with paper.
The cap is opened and the membrane removed.
1. Place the motor bike on the stand.
2. Open the plug (point 1) and remove the diaphragm (point 2) son the brake fluid thank that supplies the caliper to be removed.

3. Connect a transparent pipe to the bleed plug (point 3) of the caliper and place a container at the other end to collect the fluid.
4. Unscrew the bleed plug (point 3) and empty the hydraulic circuit.
The liquid supply hose is released.
5. Close the bleed plug and remove the collecting pipe.
6. Loosen the fluid supply pipe (point 4) on the caliper so that it can be unscrewed by hand later.
The safety pins are removed.
7. Remove the split pins (point 5) using a pair of pliers.
The pins and spring are removed.
8. Remove the pins (point 6) using a hammer and pin driver if necessary.
9. Remove the spring (point 7).
The pads are enlarged.
10. Separate the brake pad (point 8) gently, using a retractor or other suitable tool.
The fastening screws are unscrewed.
 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.
19. Reconnect the brake fluid supply pipe (point 4) and tighten the union with a fixed spanner to an indicative torque of 17-20 Nm. 

20. Fill the brake fluid tank with fresh fluid in compliance with the manufacturers specifications.

21. Connect a transparent pipe to the bleed plug (point 3) of the caliper and place a container at the other to collect the fluid. 

22. Open the bleed plug (point 3).

23. Operate the brake lever.

24. Reclose the bleed plug.
DANGER! Do not release the lever with the bleed plug open, as this causes air to be sucked into the hydraulic circuit.
The caliper mounting screws are tightened.​​​​​​
25. Release the brake lever.

26. Unscrew the bleed plug.

27. Operate the brake lever.

28. Repeat the four previous points until comes out without any air bubbles and the usual brake lever resistance is restored.

29. Close the bleed plug and remove the transparent pipe.

30. Tighten the bleed plug to a torque of 12÷16 Nm.

31. With the system pressurized, tighten all the caliper fixing bolts (point 9), applying the tightening torque prescribed by the vehicle manufacturer. (indicative value: 46Nm).
The membrane is carefully cleaned and the cap is replaced on the brake fluid reservoir.
32. After bleeding, the brake fluid in the tank is at the minimum level. Fully retract the pistons, pressing the pads with your hands and then top up.

33. Thoroughly clean the diaphragm (point 2) of the brake fluid tank and remove all remains of fluid.

34. Reposition the diaphragm and the plug (point 1) on the brake fluid tank and tighten all possible screws).
DANGER! If you notice any leaks from the caliper, repeat the whole procedure above in order to determine the cause and correct the defect.

35. Take the bike off the stand.

  • The used product replaced by this Product must not be installed on any other product. Property damage and personal injury, including death, could result.
  • Always check that the brake fluid level in the reservoir is between the minimum and maximum levels indicated on the reservoir. An incorrect level can cause brake fluid leaks or reduced brake system efficiency. Too much or too little brake fluid in the reservoir could cause the brakes not to perform properly, and personal injury, including death, could result.
