TIGHTENING TORQUE VALUES
Screws (3-4) 3 Nm (0.3 kgm)
Screws (7) 22 Nm (2.2 kgm)
• Top up brake fluid inside tank, see
2.12.4.
• Undo and remove the two screws (3-4). Keep the two
cable guides (5-6) with washers.
• Undo and remove the two screws (7). Keep the brake
caliper (8). Before refitting apply Loctite
®
on screw
threads (7).
• Position the brake caliper (8) as high as possible.
• Remove the rubber cap from the bleed valve (9).
• Insert one end of a transparent plastic tubing inside the
caliper bleed valve (9) and the other end in a container
for collection.
• Operate the brake lever repeatedly, then keep it fully
pulled.
• Loosen the bleed valve by ¼ of a turn so that the brake
fluid can flow inside the container. The tension on the
brake lever will thus be eliminated and you will be able
to take it to the end of stroke.
• Repeat this last procedure until no air bubbles can be
seen inside the fluid flowing inside the container.
NOTE When bleeding the hydraulic circuit, fill the tank with
the suitable quantity of brake fluid. Make sure that during this
procedure some brake fluid is always present inside the tank.
• Tighten the bleed valve (10) and remove the plastic
tubing.
• Top up to the correct brake fluid level, see
2.12.4.
• Refit the rubber cap (1).
