aPrefill the hydraulic tappet using the new syringe (by
gravity).
aRefit the part(s) concerned.V - BLEED PROCEDURE AFTER A REMOVING A
COMPONENT OF THE HYDRAULIC CIRCUIT.
aKeep 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.
aRemove the bleed plug from the clutch slave cylin-
der.
aConnect 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.
aOpen the bleed screw.
aFill the brake fluid master cylinder reservoir until
brake fluid flows out of the bleed screw.
aConnect a new syringe containing 60 ml of ap-
proved brake fluid to the end of the transparent pipe.
aSlowly 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.
aClose the bleed screw.
aRemove the transparent pipe from the bleed hole.
aRefit the bleed plug.
aTop up the brake fluid level in the master cylinder
reservoir.
aDisengage and engage the clutch quickly around
twenty times.
aCheck that the clutch system is operating correctly.
aRepeat the bleed operation if necessary.
aCheck the adjustment of the switch. (see 37A, Me-
chanical component controls, Clutch pedal
switch: Removal - Refitting, page 37A-52) (37A,
mechanical control elements).

Note:
Take care not to disrupt the adjustment of the
clutch start of travel switch.
Note:
The transparent pipe must remain at the same
height as the master cylinder reser voir to prevent
air from enter ing inside the clutch circuit.
