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 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.
