DESCRIPTION AND OPERATION AXLE LOCATION
The front axle is controlled longitudinally, by two forged steel radius arms and transversely by a panhard rod.
Front axle suspension
1. Panhard rod - transverse location
2. Radius arms - longitudinal location
3. Coil springs
4. Shock absorber
Long travel coil springs and hydraulic shock absorbers, provide the springing for each wheel.

REAR SUSPENSION

DESCRIPTION AND OPERATION AXLE LOCATION
Longitudinal location of the rear axle is by solid round section steel link arms and a forged "A" frame, upper link
assembly, which is secured to a chassis cross member and provides transverse control. Long travel coil springs
and hydraulic shock absorbers provide the springing for each wheel.
Rear axle suspension
1. "A" frame, upper link assembly - transverse location
2. Lower link assembly - longitudinal location
3. Coil springs
4. Shock absorber

REPAIR GENERAL BRAKE SERVICE PRACTICE
Brake fluid precautions
WARNING: Do not allow brake fluid to
come into contact with eyes or skin.
CAUTION: Brake fluid can damage
paintwork, if spilled wash off immediately
with plenty of clean water.
CAUTION: Use only correct grade of brake
fluid. If an assembly fluid is required use
ONLY brake fluid. Do NOT use mineral oil,
i.e. engine oil etc.
CAUTION: Thoroughly clean all brake
calipers, pipes and fittings before
commencing work on any part of the brake
system. Failure to do so could cause foreign
matter to enter the system and cause damage to
seals and pistons which will seriously impair the
efficiency of the brake system.
·To ensure the brake system efficiency is not
impaired the following warnings must be
adhered to :-
·DO NOT use any petroleum based cleaning
fluids or any proprietary fluids containing
petrol.
·DO NOT use brake fluid previously bled from
the system.
·DO NOT flush the brake system with any fluid
other than the recommended brake fluid.
The brake system should be drained and flushed
at the recommended service intervals.
Cover all electrical terminals carefully to make
absolutely certain that no fluid enters the
terminals and plugs.FLUID LEVEL CHECK / TOP UP
WARNING: Clean reservoir body and filler
cap before removing cap. Use only fluid
from a sealed container.
1.Park vehicle on level ground.
2.Check level is between 'MIN' and 'MAX' marks.
3.If level is below 'MIN' mark top up fluid level to
'MAX' mark on reservoir, using correct fluid.
See
LUBRICANTS, FLUIDS AND CAPACITIES,
Information, Recommended Lubricants and
Fluids
Do not fill reservoir above maximum line

REPAIR FRONT BRAKE CALIPERS
Service repair no - 70.55.03
Service repair no - 70.55.16
Service tool:
LRT-70-500 - Piston clamp
Before starting repair refer to general brake service
practice.
See General Brake Service Practice
Remove caliper
1.Loosen front wheel retaining nuts, raise front of
vehicle, lower onto axle stands, remove wheels.
2.Expose flexible brake hose by moving coiled
protective covering.
3.Using a recognised hose clamp, clamp hose to
prevent loss of brake fluid.
4.Disconnect rigid brake pipe from flexible hose,
seal exposed ends to prevent ingress of dirt.
5.Remove split [cotter] pin, retaining pins and
springs, withdraw pads. If refitting pads, identify
them for assembly to original locations.
6.Loosen bolts and remove caliper.
Repair
Do not separate caliper halves
7.Clean outer surfaces of caliper using aerosol
brake cleaner.
8.Using special tool LRT-70-500, clamp pistons in
inboard half of caliper. Gently, keeping fingers
clear, and withCAUTION,apply air pressure to
fluid inlet port to expel pistons. It is unlikely that
pistons will expel at same time, regulate rate
with a suitable piece of wood between
appropriate piston and caliper.
9.Finally remove pistons, identifying them with
their respective bores.
10.Remove wiper seal retainer by inserting a blunt
screwdriver between retainer and seal. Pry
retainer carefully from mouth of bore.
11.Taking care not to damage seal grooves, extract
wiper seal and fluid seal.
12.Clean bores, pistons and seal grooves using
clean brake fluid only. If caliper or pistons are
corroded, or their condition is not perfect, new
parts must be fitted.
