HYDRAULIC CLUTCH CONTROL: CHECKS AND ADJUSTMENTS
B2BP04XC
IMPERATIVE: Use only new brake brake fluid that is not emulsified, avoid any
ingress of impurities into the hydraulic circuit.
IMPERATIVE: Do not use automatic bleeding equipment
(risk of the brake fluid
emulsifying in the hydraulic circuit).
Couple a transparent tube (5)on the bleed screw, at «c».
Submerge the end of the tube (5)in the recipient containing the brake fluid, located
below the level of the clutch slave cylinder.
Use the transparent tube (5) to act as a siphon, at «b».
WARNING: the end of the tube (5) must be submerged in the brake fluid.
Open the bleed screw at «c».

HYDRAULIC CLUTCH CONTROL: CHECKS AND ADJUSTMENTS
Bleeding the hydraulic clutch control
Action the clutch pedal manually through its full travel: 7 timesrapidly down and up.
Allow the clutch pedal to come back up to its high position.
Fill the brake fluid reservoir to the maximum of its capacity.
Open the bleed screw at «c».
Action the clutch pedal manually through its entire travel: 7 times
rapidly down and up.
The last time, keep the clutch pedal fully down.
Reclose the bleed screw, at «c».
If necessary, repeat the operation.
Top up the brake fluid to the MAX.level of the brake fluid reservoir.
Work the clutch vigorously 40 times
.
Start the engine.
Apply the handbrake.
Engage a gear.
Check that the clutch starts to engage at a dimension (X)greater than or equal to 45 mm
(the dimension (X)is
given as a guide).
Repeat the bleed operations if necessary.

STEERING
CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Fill the power steering reservoir to the max.mark «a»on the cap (4).
Engine stopped, move the steering slowly from lock to lock, in both directions approx. ten times.
Top up the fluid to the max. mark «a»on the cap (4).
Run the engine at idle for 3 minutes, without any action on the steering wheel.
Move the steering from lock to lock, until there is no longer any tight spot.
Top up the level if it again goes down.
Bleed the circuit by moving the steering several timesin each direction.
Top up the level if it again goes down.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.

BLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit with the bleed apparatus.
Connect the bleed apparatus [1]on the brake fluid reservoir (4).
Adjust the apparatus pressure to 2 bars.
For each brake circuit:
- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the brake fluid flows out without air bubbles.
- Close the bleed screw.
- Remove the bleed apparatus [1].
Check the level of the brake fluid
(between the «DANGER»level and the «MAXI»level).
Fill if necessary with the the approved and recommended synthetic brake fluid.
