- The replacement must be made with greater residual thickness if the pad has not worn evenly. A 0.5 mm thickness difference in the residual friction material is permitted
Refitting
To fit, proceed as follows:
- Insert the two pads in the callipers.
- Screw the two pad lock pins to the correct torque, and apply the recommended product.

Rear - combined Remove the rubber cap from the bleed screw. Insert a rubber pipe in the bleed screw to permit the brake fluid to be recovered. With the left-had brake lever, load the system and bring it up to the required pressure. Keeping the left-hand brake lever pulled, loosen the bleed screw to permit the air in the system to escape. Then tighten the bleed screw Repeat the operation until only brake fluid comes out of the rubber pipe. Remove the fluid recovery pipe and refit the rubber cap over the bleed screw. Top up the brake fluid to the right level in the reservoir.
