SymptomPossible Source(s):Action(s)
SymptomDescription
Age Deterioration Cracking and crazing of the tread and side wall rubber, sometimes accompanied by carcass
deformation. An indication that the tyres have been in service for a very long time.
Neglected Cut Damage through accidental cuts or penetrations will extend in use due to continued flexing and /
or ingress of moisture and road matter.
Impact Fracture Resultant damage from impact fractures is not always visible externally and, therefore, as a safety
precaution the tyre should be removed and examined.
Casing fracture caused by severe localized impact through driving over kerbs, hitting potholes
and / or objects in the road.
A double fracture caused by crushing the side wall of the tyre between an object and the rim
flange.
In both instances, such damage can lead to sudd en and dangerous tyre deflation some time after
the impact occurred.

Hand Brake (06.05)
Description
The handbrake control lever is located on the outside of the drivers seat and brakes the rear road wheels through a cable
system and two mechanical handbrake Calipers. Handbrake pads are applied by the mechanical brake Calipers (x2), one
acting on each rear road wheel brake disc. The Calipers are bo lted to the vertical links. Return springs on each Caliper
retract the pads when the parking brake is released.
Wear in the parking brake pads is compensated for automati cally by a mechanism within the calipers. Cable stretch is
compensated by cable adjusters.
A handbrake switch is wired normally closed. The switch is he ld open whilst the handbrake is ‘off’ and closes when the
handbrake is applied. The handbrake warning lamp on the instrument panel is illuminated when the handbrake is applied.

Anti-lock Braking System (ABS) (06.09)
Brake system (06.00)
Issue 4, November 2008 Workshop Manual 6-9-1
Brake system (06.00)
Anti-lock Braking System (ABS) (06.09)
The anti-lock braking system (ABS) is a four-channel system
having independent inputs from all four-wheel speed
sensors.
The ABS module, monitors signals from the sensors to
calculate, brake slip and the acceleration / deceleration of
individual wheels. When the brake pedal is depressed, and
the ABS module detects incipient wheel lock-up from the
incoming signals, it triggers the re-circulation pump inside
the module’s hydraulic modulator, and the solenoid valves
for the wheel(s) concerned. Brake pressure, is then
modulated to increase / decrease or remain constant at the
wheel(s) concerned until whee l lock-up is eliminated. The
ABS provides self-diagnosis and any malfunction within the
system will be indicated to the dr iver by the illumination of
the brake warning light and ‘ABS FAULT’ displayed in the
message centre right. Should a fault develop within the ABS,
the brake system will operate conventionally and with the
same standard of performanc e as a vehicle not equipped
with ABS.
Dynamic Stability Control
Dynamic Stability Control (DSC ) is a closed-loop system
designed to enhance driving safety by improving vehicle
handling when the tyres are at the limits of their grip
capabilities. This is achieved through instantaneous,
electronically controlled, reduction of engine torque and
strategic application of the brakes at individual wheels.
By using the principle that by controlling the brakes
individually it is possible, to an extent, to steer the vehicle.
This principle can be used to enhance driving safety by
correcting the vehicle’s yaw moment (turning force), when
the vehicle fails to follow th e driver’s steering inputs.
Concept
Satisfactory handling is determined according to whether a
vehicle maintains a path, wh ich accurately reflects the
driver
