Brake Actuation System (06.06)
Description
Tandem Master Cylinder
The short-stroke tandem master-cylinder controls two
separate brake circuits which are jointly activated by the
brake pedal. In the event of a major leak in one system, the
other will still function. The two systems are supplied by a
common brake fluid reservoir.
A pressure sensor attached to the master-cylinder provides
the ABS / DSC module with brake pressure information. This
information informs the system how hard the driver is
braking and is used as an aid for the ABS / DSC to achieve
accurate brake pressure control.
Brake Fluid Reservoir
The brake fluid reservoir is mo unted directly on the tandem
master cylinder and secured with a pin. Two stub pipes, on
the base of the reservoir, locate into the primary and
secondary chambers of the tandem master cylinder.
An integral fluid-level switch is incorporated in the reservoir.
If the brake fluid level is low, the brake warning lamp in the
Driver Information Module (D IM) will illuminate and ‘LOW
BRAKE FLUID’ will be displayed in the message center right.

Brake System (06.00)
Power Brake System (06.07)
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.

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

difference between the ideal and actual response within a
tolerance band. This directly influences the forces on the
tires to generate a corrective yaw moment to reduce the side
forces of the tires where appropriate
System Overview
The DSC system embraces capabilities far beyond that of
ABS, or ABS and traction control combined, while relying on
the components of these systems. It also incorporates these
additional sensors for measur ing the vehicle’s motion and
brake system pressure:
Ya w r a t e s e n s o r - located centrally on the transmission
tunnel.
Lateral acceleration sensor - integrated with the yaw rate
sensor.
Steering angle sensor - located on the upper steering
column.
Pressure transducer - located on master cylinder.
The ABS / DSC module supports data exchange with other
vehicle electronic systems via the CAN network; the module
also enables diagnostic interrogation using WDS.
The following components register driver demand and the
ABS / DSC module processes their signals as a basis for
defining an ideal response:
PCM - position of accelerator pedal.
Brake master cylinder pressure transducer - driver’s
braking effort.
Steering angle sensor - position of steering wheel.
There are many supplementary parameters also included in
the processing calculations these include the coefficient of
friction and vehicle speed. The ABS / DSC module monitors
these factors based on signals transmitted by the sensors for:
• Wheel speed
• Lateral acceleration
• Brake pressure
• Yaw rate
Using these parameters, the function of the ABS / DSC
module is to determine the current vehicle status based on
the yaw-rate signal and the slip as estimated by the ABS /
DSC module. It then maintains the vehicle response within
a tolerance of the ‘normal’ behaviour, which is easily
controlled by the driver.
In order to generate the desired yaw behaviour the ABS /
DSC module controls the selected wheels using the ABS
hydraulic system and engine control system. In the event of
engine intervention, the ABS / DSC module calculates the
torque which should be supplied by the engine to the
wheels, and relays this request signal to the PCM which
implements the torque request.
The PCM receives signals from the DSC system via the CAN
bus and reduces engine torque as follows:
• The throttle is positioned to provide the requested engine target torque. • During the transient phase of torque reduction caused by
mechanical and combustion delays, other alternative
torque reduction methods are used to provide a quicker
response.
• The ignition is retarded and / or the fuel is cut-off at the injectors at selected cylinders.
• Ignition and fuelling are reinstated when the engine torque reaches the requested value
Operation Summary
• DSC is switched ‘ON’ when the engine is started
• When the system is operating , the DSC light in the instrument cluster will flash, at the rate of twice a second
• DSC can be switched ‘OFF / ON’ by pressing the DSC switch
• The DSC light in the instru ment cluster will illuminate
continuously when the system is switched ‘Off’.
• ‘DSC OFF’ will be displayed in the message centre right to indicate the system has been switched ‘OFF’
• A malfunction in the traction control system will be indicated to the driver by the following:
• The DSC light in the instru ment cluster will illuminate
continuously
• The message ‘DSC NOT AVAILABLE’ will be displayed in the message centre right
• If vehicle speed control is engaged it will automatically disengage when traction control is operating .
Traction Control
Traction control is a function of DSC, and is operated in
association with DSC. Traction control prevents excessive
wheel-spin at standing starts, or during acceleration. Wheel-
spin is usually caused by ex cessive use of the accelerator
pedal, or slippery, loose or bumpy road surfaces. To prevent
excessive wheel-spin and mainta in vehicle stability such
situations are overcome by the intervention of the traction
control system by:
• Braking the driven-wheel when it starts to slip
• And / or adapting the engine torque to a level corresponding to the traction available on the road
surface.
Functional Description
Traction control uses the ABS electronic and mechanical /
hydraulic hardware with additional valves to control the
braking pressure at the calipe rs. An engine interface also
enables the engine to respond to torque reduction requests
from the traction control. As with ABS, the signals from the
wheel-speed sensors are supplied to the ABS module, where
they are used to calculate the wheel-slip of the individual
wheels. Traction control intervention is initiated if the slip at
one of the wheels is excessive.

Brake system (06.00)
Issue 4, November 2008 Workshop Manual 6-9-3
Engine Intervention
In the event of wheel-slip the ABS / DSC module calculates
the torque, which should be applied by the engine to reduce
the wheel-slip (this torque does not exceed driver demand).
Engine torque reduction is then requested from the PCM via
the CAN bus. The PCM, in response to these signals, reduces
engine torque by controlling the ignition and fuelling. A
traction control gearshift pattern is automatically selected
within the automatic transmission software whenever
traction control is active.
Brake Intervention
This function operates by increasing the pressure in the
brake caliper of the slipping wheel, by closing the separation
valve and the inlet valve of the non-slipping wheel and
running the modulator pump. This takes fluid from the fluid
reservoir via the non-actuated master cylinder and
pressurizes the brake caliper. The pressure is modulated at
the caliper via the inlet and outlet valves to achieve the
desired wheel-slip target to maximize traction.
