Adjustment.
IMPERATIVE: Respect the safety and cleanliness requirements.
Raise and support the vehicle.
Remove the central console.
WARNING: Check the routing of the brake cables under the vehicle.
Release the handbrake lever.
Press gently on the brake pedal
(then repeat the operation 3 times).
Action the handbrake lever with a force of 40 daN.
Use a feeler gauge at «J»to measure the movement of the lever in relation to its stop.
NOTE:The movement should be less than 1,5 mmand more than 0,05 mm.
(1)Nut for adjusting the tension of the handbrake cables
Move the nut (1)to obtain a movement «J»less than or equal to 1,5 mm.
Action the handbrake lever 8 timeswith a force of 40 daN.
With the handbrake released, check the movement «j»with a feeler gauge.
NOTE:The movement should be less than 1,5 mmand more than 0,05 mm.
Refit the central console
(see corresponding operation).
Check the efficiency of the handbrake.

BLEEDING AND FILLING THE BRAKING SYSTEM
Filling the braking circuit.
WARNING: Use only the approved and recommended hydraulic fluids.
IMPERATIVE: Only use new brake fluid that has not emulsified; avoid any introduction of
impurities into the hydraulic circuit.
Fill the brake fluid reservoir (4).
Bleeding the primary braking circuit.
WARNING: During the bleed operations: take care to maintain the level of the brake fluid
in the reservoir, keep it topped up.
WARNING: The ABS system must not be in action during the bleed operation.
WARNING: Respect the sequence for the opening of the bleed screws.
Front brake caliper : Bleed screw (8).
Rear brake caliper : Bleed screw (9).
Bleed each brake caliper, proceeding in the following sequence:
- Front LH wheel.
- Front RH wheel.
- Rear LH wheel.
- Rear RH wheel.

BRAKESBLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit without the bleed apparatus.
NOTE:Two operators are necessary.
For each brake circuit:
- Apply the brake pedal to place the circuit under pressure.
- 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 fluid flows out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
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.Bleeding the secondary braking circuit.
WARNING: During the bleed operations: take care to maintain the
level of the brake fluid in the reservoir, keep it topped up.
NOTE:The bleed apparatus [1]is still connected on the brake fluid
reservoir (4).
Use the diagnostic tools [2]or [3].
Select the menu corresponding to the vehicle:
- ABSmenu
(according to equipment).- ESPmenu (according to equipment).
Follow the instructions of the diagnostic tool.
At the end of the bleed programme, check the level of the brake fluid,
top up if necessary.
Check the travel of the brake pedal: it must not be excessive. If it is,
restart the bleed procedure.
