Brakes
Parking Brake Adjusfmenf
Cable slack must be removed by adjustment of the intermediate cable length. The handbrake should be fully on be-
tween three and five clicks.
Parking Brake Shoe Assembly
The parking brakes are of the duo-sewo type. The expander
assembly (6 Fig. 1) is mounted on the backplate mounting
lug. The brake shoes locate on the expander assembly and
the adjuster
(1 Fig. I).These are held in position by the upper
and lower return springs (4 and 5 Fig. 1) and the hold down
springs (2 Fig. 1). The adjuster allows manual adjustment of
the brake shoes.
To remove the brake shoe assemblies the handbrake must
be released and the adjuster slackened.
The use of
a spring removal tool is recommended when re- moving the brake shoes. Strong pliers may be used, but
there is a risk of both personal injury and loss of compo- nents, should the pliers slip.
lnspedion and Cleaning
Clean and examine all components for wear or damage, re- newing parts as necessary. Fig.
1
When
reassembling the expander assembly, liberally grease the components using a proprietary mechanical brake
grease. Lightly grease the threads of the adjuster.
CAUTION: Do not get grease onto the lining material. Light surfacecontamination can be removed with emery cloth,
but heavy penetration of grease or fluid will render the material unsuitable for further use and the linings
must be renewed.
Re-assembly
When reassembling the brake shoes, lightly grease the shoe tips and back plate contact area. The brake shoes and
the expander assembly should befitted to the backplate with the lower return spring in position. When the brake shoes
are located, the adjuster, upper return spring and hold down springs should then be fitted. The brake shoes should
be adjusted
so that the brake rotorhub can just be fitted. Final adjustment should allow the brake rotor/hub to rotate
without excessive drag. Light running contact is permissible.

12.3 BRAKE FLUID LEVEL CHECK
WARNING: AVOID SKIN / EYE CONTACT OR INGESTION OF BRAKE FLUID. IF SKIN OR EYES ARE ACCIDENTALLY
SPLASHED WITH BRAKE FLUID, RINSE THE AFFECTED AREA IMMEDIATELY WITH PLENTY OF WATER
AND SEEK MEDICAL AlTENTlON IMMEDIATELY.
Checking the fluid level
CAUTION: 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.
Correct brake fluid level is essential for the efficient oper- ation of the brake system. Check that the fluid level is be- tween the MAXand MIN marks on the fluid reservoir (Fig. 1). Top up if necessary with recommended brake fluid.
BMQ: The efficiency of the brakes may be impaired if fluid
is used which does not meet specifications. Use
ONLY brake and clutch fluid that conforms to
a mini- mum DOT 4 specification. Also do not use brake
fluid that has been exposed to atmosphere for any
length of time. Moisture absorbed from the atmos
- phere impairs the efficiency of the brake fluid.

15.1.13 Spillage and Leakage
If material is spilled or released,contact Jaguar Service for clean up procedures. All other personnel must be kept away
from contaminated area.
Do not dispose contaminated propellant or water into storm or sanitary sewers, ground water or soil.
Spills may be reportable to local state,
and/or federal authorities.
Material should
be disposed of by incineration or chemical oxidation under carefully controlled conditions by specially
trained individuals in accordance with local State and Federal regulations.

15.1.14 Scrapping Vehicles With Live Airbag(s)
When scrapping a vehicle with a live airbag, first deploy the
airbag in accordance with following procedures. This
procedure assumes airbag wiring is undamaged.
See Handling
/ Safety information.
If the airbag is
to be removed see Airbag Modules Assembly/ Removal/Service Instructions.
Equipment required: Insulation Displacement Connectors
(IDC) (Scotchloks) (two-off), battery, two-off ten meter
lengths of lmm2 wire fitted with crocodile clips at one end. (See Fig. 1).
WARNING: THE DEPLOYMENT PROCEDURE SHOULD BE PERFORMED OUTDOORS AWAY FROM OTHER
PERSONNEL.
Remove any loose debrisfrom around airbag and ensure no
flammable liquids are present.
Disconnect the vehicle battery. Fig. 1
Link harness conn&ion & deployment method
WARNING:
ALWAYS CONNECT TO AlRBAG FIRST, AS THE BAG WILL DEPLOY IMMEDIATELY ON CONNECTION TO
THE BATTERY.
Remove passenger side and driver side under-scuttles / knee bolster.
. Disconnect the airbag connector under the facia.
. Look for the yellow harness connectors and cut the wires originating from the airbag just above the mating plug.
w: The harness connected between the driver's airbag and the yellow connector has one red/purple feed wire and
one pinkbrown return wire.
The harness connected between the passenger's airbag and the yellow connector has two
red/purple feed
wires and one pinwpurple return wire.
Pass a 10 meter (33ft) link harness containing two lmm2 wires through the window aperture, and connect using an
. Close all doors, leave window with lead open.
. Ensure no personnel are in the car or in the area around the car.
. Move back 10 meters (33ft) and connect harness crocodile clips to battery: the airbag will immediately deploy.
Allow the unit to cool for at least 20 minutes. Cooling modules should be continuously monitored to ensure heat

- A3.2.19 Unified Thread Identification - Bolts
A circular recess is stamped in the upper surface of the bolt
head (1 Fig. 1).
A3.2.20 Unified Thread Identification - Nuts
A continuous line of circles is stamped on one of the flats of
the hexagon, parallel to the axis of the nut (2 Fig. 1).
A3.2.2 1 Unified Thread Identification - Studs, Brake
Rods, etc.
The component is reduced to the core diameter for a short
length at its extremity (3 Fig. 1).
A3.2.16 Nuts
When tightening a slotted or castellated nut, never slacken it in order to insert the split pin or locking wire, but tighten
it to align the next slot. The exception is in those recommended cases where slackening the nut forms part of an adjust- ment e.g. bearing endfloat or preload adjustment. If difficulty is experienced, alternative washers or nuts should be
selected, or a washer of a different thickness used. Where self-locking nuts have been removed, replace them with
new ones.
A3.2.17 Locking Wire
Fit new locking wire of the correct type to the assemblies incorporating it. Arrange the wire so that its tension tends
to tighten the bolt heads, or nuts, to which it is fitted.
A3.2.18 Screw Threads
Metricthreads to IS0 standards and UNF threads are used. See below forthread identification. Fixings with damaged
threads must always be discarded. Cleaning the threads with a die or tap impairs the strength and closeness of fit and
is not recommended. Always ensure that replacement bolts are of equal strength to those removed. Do not allow oil,
grease or jointing compound to enter blind threaded holes because the hydraulic action which would be generated
when screwing in the bolt or stud could split the housing. Oil the thread lightly before tightening to ensure
a free run- ning thread, except in the case of self locking nuts. Always tighten a nut or bolt to the recommended torque figure.
Damaged or corroded threads will affect the torque reading. To check or retighten a bolt or screw to a specified torque
figure, first slacken by a quarter of a turn, then retighten to the correct figure.

A4.2.2 BODY ALIGNMENT
The illustrations on pages 11 - Body Dimensions PLAN, and 13 -Body Dimensions SIDE VIEW, provide specifications
for damage assessment and location of replacement parts.
These dimensions must be strictly applied whether they are used for damage assessment, component location or post
repair verification.
The plan view MASTER datums are nominated on the right
-hand side of the body with the left-hand datums dimen- sioned from them. Therefore, the right-hand datums must be known to be correct before any other cross-ar dimen- sions are checked.
W: The right-hand side is always looking towards the front, from the rear of the vehicle.
All dimensions are derived from a single
(ZERO) datum point for all three axes; X for length, Z for height and V cross- car.
