Vehicles without ABS are equipped with brake
pressure reduction valves for the rear wheel
brakes. They are located in the corresponding
brake circuits at the brake master cylinder.
Vehicles with ABS do not need brake pressure
reduction valves because they are equipped with
electronic brake distribution (EBD).
The handbrake is cable operated on the rear
brakes.
On vehicles with a petrol engine the necessary
vacuum for the brake booster is generated by the
intake manifold.
On vehicles with a diesel engine, a vacuum pump
driven by the engine provides the necessary
vacuum for the brake booster.

DESCRIPTION AND OPERATION
Brake Booster
Emergency brake assistant (EBA) EBA operates purely mechanically, and is
completely integral with the brakeservo.

effect is not achieved.
The EBA recognises from the driver's manner of
braking that an emergency situation is occurring,
and automatically applies full braking power.
This occurs in a matter of milliseconds, which is
faster than the driver could do it.
Furthermore, it was observed that after the first
heavy application of the brake pedal, the driver
releases the pressure on the pedal too early.
The EBA ensures that the ABS effect still continues
when the pedal pressure would normally lie below
the ABS range of control. The system is available
j as an option depending on market and vehicle
variant.
Function
In normal braking situations, the brake servo with
EBA operates in the same way as a conventional
brake servo unit. This means that the driver can
always modulate the brakes.
If an activation threshold defined by a characteristic
curve is exceeded during braking, the EBA
operates.
Determination of the activation threshold is based
on the pedal movement parameters, which are a
function of the pressure on the brake pedal and
the speed of movement of the pedal.
Depending on driving manner, EBA results in a The characteristic curve

The balls are now locked, and the ball sleeve can
no longer be moved in the closing direction of the

The EBA is now active, the brake pressure is
increased up to the wheel locking limit, and the

pressure point without effort.
The brake pressure remains at the ABS control
limit until the EBA is completely released again.
