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.

Brake Booster
The brake booster comprises a chamber divided by a diap hragm plate and is secured to the brake pedal housing.
As the brake pedal is pressed, a poppet valve opens allowing at mospheric pressure into the drivers side of the diaphragm.
Atmospheric pressure builds up on the drivers side of the diaphragm and pushes against the partial vacuum on the other
side. This additional force boosts the a pplied brake pedal force up to 6.5 times.
When the brake pedal is released, the poppet valve closes. The pressure on the diaphragm reduces and the compression
spring returns the diaphragm to the release position.
Emergency Brake Assist
In an emergency braking situation, a driver presses down on the brake pedal much faster than in normal braking
conditions, but often without sufficient force. The initial appli cation of the brake pedal is a reflex reaction. After the initial
application, many drivers do not brake ha rd enough because of concerns that they might cause the vehicle to skid. To aid
the driver, the panic brake assist (PBA) intervenes in bringing the vehicle to a halt, sooner and in a controlled manner, in
emergency braking situation. The PBA system monitors the speed of brake pedal activation, and at a calibrated pedal
activation speed, the PBA provides maximum brake force and makes full use of the ABS.
PBA is controlled by the ABS/DSC module, which monitors a travel sensor attached to the internal vacuum diaphragm of
the brake booster. The sensor determines the position of th e diaphragm and the speed of the diaphragm movement. If the
sensor's signal indicates an emergency braking situation, the
ABS/DSC module will open an electric solenoid on the brake booster. The solenoid directs atmospheric pressure into the
rear of the brake booster, causing the booster diaphragm to mo ve forward to fully apply the brakes. PBA takes full benefit
of ABS to stop the vehicle in a controlled manner and in the shortest distance possible. When the brake pedal is released
the ABS/DSC module instantly releases the brakes.

Use the AMDS to bleed the brakes if you are bleeding the
brake system after you replaced a major component, for
example: a modulator or a mast er cylinder or when filling
from empty.
If you are bleeding a caliper, you can use a manual brake-
bleed procedure.

WA R N I N G
BRAKE FLUID THAT CONTAINS WATER CAN AFFECT THE PERFORMANCE OF THE BRAKES AND CAUSE CORROSION IN THE BRAKE SYSTEM.
IF YOU KEEP BRAKE FLUID IN OPEN CONTAINERS, IT WILL ABSORB WATER VAPOUR.
USE ONLY BRAKE FLUID FROM NEW CONTAINERS
WHEN YOU TOP-UP THE BRAKE FLUID RESERVOIR..
When you bleed a brake caliper, always bleed the inner bleed screw first, followed by the outer bleed screw, then bleed the inne r bleed screw again.

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
