AUTIONS:
The Brembo caliper is aligned to the brak e disc when it is first installed to the vehicle, therefore, care must be taken
not to disturb this alignment. When removi ng the caliper; remove the bolts that secure the anchor bracket to the vertical
link only. DO NOT loosen any other caliper bolts.
Do not loosen bolts securing brake disc to disc mounting.
Brembo calipers and discs provide higher -performance braking using the existing hydraulic braking system. The brakes are
installed to the vehicle using unique vertical links, hubs, hydraulic hoses and disc shields.
The front brake disc consists of a ventilated, cross-drilled disc, bolted to a disc carrier. The disc assemb ly is mounted on the
wheel studs and clamped be tween the wheel and hub.
A unique feature of the front disc is th e slanted (non radial) ventilation webs which lean the opposite-way to the disc's
direction of rotation. This design enables he at generated by the disc to be dispersed by air entering at the disc's center and
being forced outwards through the cooling ducts.
Due to the use of fixed calipers in place of the standard floating caliper, certain lateral dimensions on the vertical link and

CAUTI O
N: The Brembo caliper is aligned to
the brake disc when it is first installed to the vehicle, therefore, care must
be taken not to disturb this alignment. When removing the ca liper; remove the bolts that secure the anchor bracket to the
hub carrier only. DO NOT loos en any other caliper bolts.
Brembo calipers and discs provide higher -performance braking using the existing hydraulic braking system. The brakes are
installed to the vehicle using unique hub carr iers, hubs, hydraulic hoses and disc shields.
The rear brake disc is a single piece co nstruction which is ventilated and cross-drilled. The disc is mounted on the wheel
studs and is clamped between the wheel and hub. Cooling ducts run through the ce nter of the brake disc to provide the
required ventilation to keep the disc cool under operating conditions.
Modified disc shields are installed to accommodate the larger diameter discs.
Due to the use of fixed calipers in place of the standard floating caliper, certain lateral dimensions on the hub carriers and
hubs are critical to achieve correct cleara nce and operation of the brakes. Therefore special hub carriers and hubs set within
a certain tolerance are inst alled with Brembo brakes.
The four cylinder brake caliper is rigidly attached to the vert ical link via an anchor bracket. The caliper is a split assembly
with each side of the caliper, housing two pistons. The two-pairs of opposed pistons act direct ly on the brake pads mounted
one each side of the disc.

Rear Disc Brake - Brembo

Body Structure
Introduction
The standard wheelbase Jaguar sedan has a unit construction monocoque body structure with bolt-on front fenders and
welded rear fenders. The doors feature lif t-off hinges and welded drop-glass frames.
Constructional Steel Classification
BODY ALIGNMENT
The Body Dimensions Plan, and Body Dimensions Side View, provide specified BIW dimensions to facilitate damage
assessment and location of replacemen t parts. These dimensions must be strictly applied when used for damage
assessment, component location or post repair verification.
• NOTE: The right-hand side is always looking towards the front, from the rear of the vehicle.
The nominated plan view master datums are on the right-hand side of the body with the left-hand datums dimensioned
from them. Right-hand datums must therefore be known to be correct before any other cross-car dimensions are checked.
Datum location, Example
The Front Master Datum (front crossmember rear mounting at the inner face of the main floor RH longitudinal) is nominally
359,5mm to the right-hand side of the body center line. The LH side fron t datum is measured 717,0 / 721,0mm from the
RH. Refer to the Body Dimensions Plan.
Expressed as a true posi tion in three planes, the front master datum is:

Inset A, shows the 25° - 35°angled cut-away at front edge. The front end of the coachlines should terminate 50mm - 60mm behind the headlamp apertures and the two sides must be symmetrical.
The 1.25mm - 1.75mm wide coachline (inset B), terminates with vertical face and ends 10mm - 20mm forward of tail lamp
aperture.
Inset C shows the upper edge of the coac hline positioned 6mm - 8mm below feature line along the body side. Inset D shows

Other Models

Inset A, shows the angled cut-away at 25° - 35° at front edge. The front end of coachlines terminate 50mm - 60mm behind
the headlamp apertures.The two sides must be symmetrical.
The 3mm - 3.5mm wide coachline shown in Inset B, terminates with vertical face and ends 10mm - 20mm forward of tail
lamp aperture.
Inset C shows the upper edge of th e coachline positioned 6mm - 8mm be low the body side feature line.
Paint
Two-pack solid color paint can be applied. Following application of paint by hand brus h or suitable air brush, allow the paint
to dry fully before peeling away the remain ing strips of Striping Tape. The paint takes in excess of 12 hours to air dry and
fully harden, curing can however be accelerated by careful application of heat from infra-red lamps..
• NOTE: Masking tape must only be removed when the paint has hardened.
For the repair of minor damage (cuts, et c.), Paint Touch-up Pens in the colours required, are available via Jaguar Parts
Operations.

• NOTE: The above table refers to water borne paint introduced on 1998MY vehicles. This paint is identified by a four figure
number commencing with a 1. Solvent-based paint is identified by the same succeeding three figures, but this is followed by three different letters. E.G. JBC1712 JHG Westminster Blue is a water-borne paint. JBC712 JFG Westminster Blue is a
