A poorly adjusted parking brake:
-prevents correct operation of the automatic compen-
sation system for the brake shoes,
-causes premature wear of brake shoes.
ADJUSTMENT
I - ADJUSTMENT PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) .
aApply the parking brake five times to condition the
cables for normal use.
aPut the parking brake lever into the released posi-
tion.
aCheck that the rear wheels turn freely. If they do not,
check the following components and if necessary re-
pair:
-the parking brake cables,
-the calliper piston,
-the automatic compensation system,
-calliper

I - PRECAUTIONS DURING REPAIR
Risks relating to contamination.
aThe hydraulic clutch system is very sensitive to con-
tamination. The risks caused by contamination are:
-impossible to change gears,
-damage to or destruction of the clutch system,
-leaks on the hydraulic circuit.
All the operations on the hydraulic clutch circuit sys-
tem must be carried out under excellent cleanliness
conditions. This ensures that no impurities enter the
hydraulic circuit during the operation.
The cleanliness principles apply to all components
of the hydraulic clutch circuit.
Items causing contamination are:
-metal or plastic swarf,
-fibres:
•cardboard,
•brushes,
•paper,
•clothing,
•cloth,
•dust and particles in the air,
•etc.
Cleaning cloths.
aUse lint-free cleaning cloths (see Products recom-
mended for the repair) (04B, Consumables - Prod-
ucts).
Each cloth must only be used once.There are two types of equipment used to bleed the
clutch circuit:
aARC50 via the brake fluid reservoir.
aSyringe via the bleed hole located on the clutch
slave cylinder.
There are two procedures used to bleed the clutch
circuit:
aIf no parts of the hydraulic clutch circuit are remo-
ved:
-Carry out the bleed operation using the ARC50 via
the brake fluid reservoir or using a new syringe via
the bleed hole located on the clutch slave cylinder.
aIf no parts of the hydraulic clutch circuit are remo-
ved:
-Only carry out the bleed operation using a new sy-
ringe by injecting the brake fluid via the bleed hole
on the clutch slave cylinder.
Consumables required for the repair:
aBleed the clutch circuit using approved (see Vehi-
cle: Parts and consumables for the repair) brake
fluid (04B, consumables - products).
II - PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aRemove the engine undertray. Equipment required
brake circuit bleeding device
hydraulic circuit bleed syringe
Note:
-Even the tiniest air bubble in the circuit can
cause faulty operation (pedal failing to return
properly, crunching sound when changing gear,
etc.).
-Incorrect bleeding can lead to incorrect detec-
tion of faults and unnecessary part replace-
ments.
