BLEEDING METHOD TO BE USED:
(for two people).
1) Filling the circuit:
Check that the clutch pedal is in the top position; put
it in this position and hold it by hand if necessary.
Fill the hydraulic circuit by connecting a filling system
and applying pressure to the tank, open the bleed
screw (A) (always compensate for the force using a
counter-spanner) and allow a little fluid to escape
(approximately 0.5 l) through a transparent tube
connected to the bleed screw. Close the bleed
screw.
2) Final bleeding of the circuit:
One operator
slowly
disengages fully and keeps the
pedal depressed. Wait approximately ten seconds in
this situation. With the pedal still depressed, a
second operator opens the bleed screw briefly (A).
With the bleed screw closed again, the operator
inside the vehicle releases the clutch pedal and
slowly lifts it to top position by hand (
It is normal that
the pedal does not return independently in this
configuration
).
After a few seconds repeat the operations described
above in 2) as often as required until no more
bubbles escape when bleeding. Then repeat these
operations five times to ensure that the system has
been bled correctly.
These repeated bleedings allow the slave cylinder to
eject all the air trapped in any section between the
stop and the bleed screw and which has not been
"cleaned" by the flow of liquid when refilling using the
traditional pressurisation system.
An air bubble in the circuit, no matter how small, may
lead to operating faults such as: incorrect pedal
return, crashing of the gears,..., which may lead to
incorrect fault finding and unnecessary replacement
of a component in the clutch circuit.
