12.4 BRAKE SYSTEM BLEEDING
WAR-: GREAT CARE MUST BE EXERCISED WHEN SERVICING OR REPAIRING THE SYSTEM. AVOID SKIN/ EYE
CONTACT OR INGESTION OF BRAKE FLUID. IF SKIN OR EYES ARE ACCIDENTALLY SPLASHED WITH
BRAKE FLUID,
RINSETHE AFFECTED AREA IMMEDIATELY WITH PLENTY OF WATER AND SEEK MEDICAL
ATTENTION. IF BRAKE FLUID IS INGESTED, SEEK MEDICAL ATTENTION IMMEDIATELY.
CAUm: Fluid must not be allowed to contact the vehicle paintwork. Remove any spilt fluid from the paintwork
by rinsing away with running water. Methylated spirit (denatured alcohol) must not be used to clean the
contaminated area.
CAUTION: Never use methylated spirit (denatured alcohol) for component cleaning purposes. Use only a proprietary
brake cleaning fluid.
WARNING : THROUGHOUT THE FOLLOWING MAINTENANCE / SERVICE OPERATIONS, ABSOLUTE CLEANLINESS
MUST BE OBSERVED TO PREVENT FOREIGN MATTER CONTAMINATING THE BRAKE SYSTEM.
12.4.1 System Bleeding - General Instructions
Use a brake bleeder bottle with a clear bleeder tube. Also recommended is a filler unit with a fill pressure of 1.0 bar. If a filler unit is not used, ensure that their is sufficient brake fluid in the reservoir throughout the bleeding procedure.
m: Always bleed the caliper furthest away from the actuation unit first. On right hand drive vehicles, bleed in the
following order: front
left (FL),front right (FR), rear left (RL) and rear right (RR). On left hand drive vehicles bleed in the following order: FR, FL, RR and RL.
12.4.2
. Ensure that the vehicle is standing level. Switch the igni-
tion off.
Check that the fluid level in the reservoir is between the min and max marks.
. Connect the bleeder bottle tube to the relevant front cali- per (see'note' above) bleeder screw (1 Fig. 1) and open the
screw.
rn Bleed until new, clear, bubble free fluid is observed in the
tube and then close the bleeder screw.
. Repeat this procedure at each remaining caliper.
With the motorrunning check brake pedal travel.
If excess- ive, check for leaks and repeat the bleed procedure.
Fill the reservoir to the max level.
System Bleeding After Brake Fluid Renewal
12.4.3 System Bleeding After Tandem Master Cylinder
Renewal
Ensure that the vehicle is standing level. Switch the igni- tion off.
rn Check that the fluid level in the reservoir is between the min and max marks.
Connect the bleeder bottle tube to the relevant front cali- per (see'note'above) bleederscrew(1 Fig. 1) and open the
screw.

12.5.2 Hoses
Fully release the unions (1 Fig. 1) securing each end of the
hose to the fluid pipes. Withdraw the pipe unions (1 Fig. 1) from the hose ends.
Plug the ends of the pipes (2 Fig. 1) to prevent the loss of
fluid and the ingress of dirt.
Remove the mounting bracket locknut (3 Fig. 1) and re- move the hose (4 Fig. 1).
Thoroughly clean the hose and examine for any signs of
wear or damage. Renew the hose if there is any doubt
about its condition. Thoroughly clean the bore of the hose
using compressed air.
. Remove all blanking plugs and fit the new hose to the cali- per / connector. Secure the hose to the mounting bracket.
. Before fully tightening the locknut, ensure that the hose is
neither kinked nor twisted.
. Bleed the brakes.
12.5.3 Pipes
. Fully release the pipe unions (1 Fig. 1).
. Withdraw the pipe (5 Fig. 1) from the vehicle. Plug the
pipes (2 Fig. 1) to prevent the loss of fluid or the ingress of dirt. Thoroughly clean and examine the pipe for signs of damage or deterioration. Renew the pipe if there is any
doubt about its condition.
Thoroughly clean the bore of the pipe using compressed
air.
. Remove all blanking plugs and fit the new pipe to the ve- hicle. Secure the pipe to the body.
. Bleed the brakes.

13.2.18 Fuel Filler Flap, Description
The fuel filler flap comprises a hinged flap attached to the body decking panel by two M5 nuts; the flap incorporates
a rubber buffer, snap
-in striker, hinge spring and the fuel cap stowage magnet. The rubber fuel bowl moulding is at- tached via a steel armature to the body reinforcement panel by five M5 nuts and is retained at the filler neck by a clip.
The mating drain tube is fitted with an internal filter.
The fuel filler flap latch mechanism attached
tothe fuel bowl armature bytwo M5 nuts, includes a locking pin and actua- tor which are both serviceable items. The latch actuator operates independently from the central locking system; it is
driven directly
by the security and locking control module. Locking of the fuel filler flap is achieved only by operation
of the key or by the remote rf transmitter.

13.4 TRUNK
13.4.1 Trunk, Description
The trunk houses the spare wheel, the battery, an electrical carrier containing electrical fuses, relays and modules and
a compact disc auto-changer attached to body bracketry. The trunk is fitted with push-fit, velour finish, liners (1 Fig. 1) to the sides and front inner panel; the trunk floor is covered with carpet attached to a removable floor board (2 Fig. 1) and a battery cover (3 Fig. I), one covering the spare wheel and wheel changing equipment, the other covering the
battery and electrical carrier.
The floor board rests on the spare wheel, the front and rear edges
of the floor board locating in blocks on the fuel tank
backboard and on the rear of the body. The blocks accommodate the two possible height settings caused by the differ- ence in thickness between the space saver and full sized spare wheels.
A tread plate (4 Fig. 1) is attached to the trunk sill and a liner is fitted to the rear of the trunk below the sill. Interior trim finisher panels are fitted to the rear lamp units accessed from the trunk opening.
The trunk lid
(5 Fig. 1) is fitted with a removable moulded liner and two trunk illumination lights; the lid is supported by two gas struts, attached through press-on fittings between the inner wheel arch and trunk hinge (6 Fig. 1). A warning
triangle is attached by a bracket to the trunk lid and retained in the open position by a rubber block (Europe inc UK only).
Trunk locking is based on a central latch and striker, operated electrically through the central locking system
by an ad- jacent actuator or by key in a barrel lock located behind the trunk lid badge.
For details on renewal
of trunk front and side liners, trunk carpet, trunk seal retainer and battery cover, see relevant

13.7.6 Repair of Damaged Carpet
The most common cause of accidental damage to carpets is cigarette burns (especially to polypropylene carpet).
These can be repaired easily on new carpets by cutting out the face material in the affected area and replacing with new face material with a latex locking coat of approximately 100g/m2 dry then incorporating a P.S.A.B. (pressure sensi- tive adhesive backing) which would be applied to roll carpet in the form of a laminate film at Firth Furnishings subsidi- ary Textile Bonding, Higham Ferrers, Northampton, UK.
The
film has a peelable release paper, which means that the new material would simply be cut to size, the release paper
removed and then the new carpet pressed into position.
The problem
in replacing areas in old or soiled carpets is that the replacement of damaged areas with new carpet would
create a visual difference, ie un-worn pile, clean appearance, which would then cause the repaired area to stand out
from the rest of the carpet. The only answer would be to abrade the rest of the new carpet to the same degree as the
old carpet.
