IDENTIFICATION - BLEEDING OF THE HYDRAULIC CLUTCH CABLE

1 - IDENTIFICATION

(1) Brake fluid reservoir .

(2) Hydraulic control master cylinder .

(3) Clutch pedal .

(4) Hydraulic control slave cylinder .

(5) Bleed screw .

2 - BLEEDING THE HYDRAULIC CIRCUIT

IMPERATIVE : use only clean fluid free from bubbles ; avoid any introduction of impurities into the hydraulic system .

Use only approved and recommended hydraulic fluid(s)DOT4 .

IMPERATIVE : do not use automatic bleeding equipment (risk of foaming of the fluid in the circuit) .

Remove :

• the style cover
• the air filter and its connections

Fill the reservoir with brake fluid (1) to its maximum capacity .

Move the reservoir to drive out the pockets of air .

Fill the reservoir with brake fluid (1) to its maximum capacity .

NOTE : it is possible to operate the clutch pedal 10 times without it being necessary to add brake fluid to the reservoir .

Connect a transparent tube to the bleed screw (5) and connect it to a receptacle situated lower than the slave cylinder (4) .

Create a siphon (A) towards the top using the transparent pipe which is in contact with the bottom of the receptacle .

Open the bleed screw (5) .

Remove the brake circuit reservoir cap (1) .

Retain the clutch pedal (3) in the lowest position (end of travel) .

Open the bleed screw (5) until there is no more pressure in the circuit .

Close the bleed screw (5) .

Raise the clutch pedal (3) manually to the highest position .

Repeat the operation until the brake fluid runs out clean and free from bubbles .

Top up the brake fluid level to the MAXI mark on the reservoir (1) .

Refit the fluid reservoir cap (1) .

Release and engage the clutch rapidly 40 times (2 manoeuvres per second) before switching on the engine .

Check that friction starts in the clutch mechanism to an extent X greater than or equal to 35 mm (Distance X is given as an indicator) .

If incorrect ; Repeat the bleed operations .

WARNING : tighten the bolt (5) to 0.75 da.Nm .
