TECHNICAL INFORMATION
FRONT BRAKE
• Top up the brake fluid reservoir.
•
Remove the rubber cap (4) of the bleed valve (5).
•
Insert one end of a transparent plastic tubing inside the
calliper bleed valve (5) and the other end in a container
for collection.
• Pull and release the brake lever repeatedly and finally
keep it fully pulled in.
•
Loosen the bleed valve by ¼ turn to let brake fluid
drain into the container; this will remove any tension
from the lever so it can reach end of travel position.
• Repeat process until the fluid draining into the
container is totally clear of air bubbles.
NOTE Add fluid to the reservoir when needed while bleeding
the hydraulic system. Make sure there is always some fluid
in the reservoir throughout the process.
•
Tighten the bleed valve (5) and remove the tubing.
• Top up brake fluid inside the reservoir up to correct
level.
• Refit the rubber cap (4).
