ROUTINE MAINTENANCE
DELAY VALVE
•
Remove the instrument panel,
•
Remove the rubber cap (1) from the bleed valve (2).
•
Insert one end of a transparent plastic tubing inside the
bleed valve (2) of the delay valve, and the other end in
a container for collection.
•
Operate the rear 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 reservoir
with the suitable quantity of brake fluid. Make sure that
during this procedure some brake fluid is always present
inside the reservoir.
•
Tighten the bleed valve and remove the plastic tubing.
•
Top up to the correct brake fluid level, see
2.10.1.
•
Refit the rubber cap.

pulled.
