V - BLEED PROCEDURE AFTER A REMOVING A
COMPONENT OF THE HYDRAULIC CIRCUIT.
a Keep the clutch pedal in the upper position using a
strap attached to the steering wheel to ensure conti-
nuity of the hydraulic circuit during the bleed opera-
tion.
Note:
Take care not to disrupt the adjustment of the
clutch start of travel switch.
a Remove the bleed plug from the clutch slave cylin-
der.
a Connect a transparent pipe of sufficient length to the
bleed hole (at least thirty centimetres) in order to
place it at the same height as the reservoir.
a Open the bleed screw.
a Fill the brake fluid master cylinder reservoir until
brake fluid flows out of the bleed screw.
Note:
The transparent pipe must remain at the same
height as the master cylinder reservoir to prevent
air from entering inside the clutch circuit.
a Connect a new syringe containing 60 ml of ap-
proved brake fluid to the end of the transparent pipe.
a Slowly inject the entire contents of the syringe into
the hydraulic clutch circuit without injecting any of
the air from the top section of the syringe.
a Close the bleed screw.
a Remove the transparent pipe from the bleed hole.
a Refit the bleed plug.
a Top up the brake fluid level in the master cylinder
reservoir.
a Disengage and engage the clutch quickly around
twenty times.
a Check that the clutch system is operating correctly.
a Repeat the bleed operation if necessary.
a Check the adjustment of the switch. (see 37A, Me-
chanical component controls, Clutch pedal
switch: Removal - Refitting, page 37A-43) (37A,
