MECHANICAL COMPONENT CONTROLS<br />
Clutch circuit: Bleeding<br />
37A<br />
JH3 or JR5 or ND0 or PK4 or TL4<br />
2 - Bleed using a new syringe.<br />
a Keep the clutch pedal in the upper position using a<br />
strap attached to the steering wheel to ensure continuity<br />
of the hydraulic circuit during the bleed operation.<br />
Note:<br />
Take care not to disrupt the adjustment of the<br />
clutch start of travel switch.<br />
a Remove the bleed plug from the clutch slave cylinder.<br />
a Connect a transparent pipe of sufficient length to the<br />
bleed hole (at least thirty centimeters) in order to place<br />
it at the same height as the reservoir.<br />
a Open the bleed screw.<br />
a Fill the brake fluid master cylinder reservoir until brake<br />
fluid flows out of the bleed screw.<br />
IV - BLEED PROCEDURE IF PARTS OF THE<br />
HYDRAULIC CIRCUIT ARE REMOVED.<br />
a<br />
WARNING<br />
The master cylinder pipe must be disconnected<br />
from its take-off point on the brake fluid reservoir,<br />
to avoid any foreign matter penetrating inside the<br />
brake system hydraulic circuit.<br />
WARNING<br />
Prepare for the flow of fluid and protect the surrounding<br />
components.<br />
Note:<br />
Prefill the hydraulic circuit pipe equipped with a<br />
filter.<br />
Position the filter head facing downwards to<br />
ensure that it fills.<br />
Note:<br />
The transparent pipe must remain at the same<br />
height as the master cylinder reservoir to prevent<br />
air from entering inside the clutch circuit.<br />
a Connect a new hydraulic circuit bleed syringe<br />
filled with a useful volume of 60 ml of approved brake<br />
fluid to the end of the transparent pipe.<br />
a Slowly inject the entire contents of the syringe into<br />
the hydraulic clutch circuit without injecting any of<br />
the air from the top section of the syringe.<br />
a Close the bleed screw.<br />
a Remove the transparent pipe from the bleed hole.<br />
a Refit the bleed plug.<br />
a Top up the brake fluid level in the master cylinder reservoir.<br />
a Disengage and engage the clutch quickly around<br />
twenty times.<br />
a Check that the clutch system is operating correctly.<br />
a Repeat the bleed operation if necessary.<br />
a Check the adjustment of the switch. (see 37A, Mechanical<br />
component controls, Clutch pedal<br />
switch: Removal - Refitting, page 37A-51) (37A,<br />
mechanical control elements).<br />
