Braking and parking
Wear
Corrosion
Electromechanical brake servo (eBKV)
The rate of wear on the brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is
a particular problem in urban traffic and
short stretches, or with very sporty driving.
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
The electromechanical brake servo only
works when the ignition is switched on and
optimises the force of the foot by increasing
the pressure that the driver exerts on the
brake pedal.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable to
clean off the pads and disks by braking firmly
Depending on the speed, the braking force
and the environmental conditions (e.g. tem-
perature, air humidity, etc.) noises may be
produced when braking.
If the electromechanical brake servo is not
working, the brake pedal must be pressed
harder, as the braking distance increases due
to the lack of assistance from the servo
brake.
a few times at a moderately high speed

Fault in the brake system
Wet roads or road salt
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to
the nearest specialised workshop and have
the fault repaired. Drive there slowly and re-
member that you will have to apply more
pressure on the brake pedal and allow for
longer stopping distances.
WARNING
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
Any anomaly in the brake system can in-
crease the braking distance, with the re-
sulting risk of an accident.
●
New brake pads and discs must be run in
and do not have the correct friction during
the first 200 km (124 miles). This reduced
braking capacity may be offset by pressing
on the brake pedal a little harder.
At high speed and with the windscreen wip-
ers activated, the brake pads will briefly
touch the brake discs. This takes place, al-
though unnoticeable to the driver, at regular
intervals to improve the response time of the
brakes when they are wet.
Low brake fluid level

been salted, braking effectiveness may be
decreased.
●
Brakes can overheat if used excessively
on slopes. Before driving down a long steep
slope, it is advisable to reduce speed and
change down into a lower gear or range.
Therefore, using the engine brake relieves
the brakes.
Brake servo
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. The layer of salt that accumulates on the
discs and pads can be removed by gently ap-
plying the brakes a few times.
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running.
