Braking and parking
At high speed and with the windscreen wipers
activ at
ed, the brake pads will briefly touch
the brake discs. This takes place, although
unnoticeable to the driver, at regular intervals
to improve the response time of the brakes
when they are wet.
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 winter. The
layer of salt that accumulates on the discs
and pads can be removed by gently apply-
ing the brakes a few times.
Corrosion
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.
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
a few times at a moderately high speed ››› .
F ault in the br
ake system
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 st
opping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
Any anomaly in the brake system can in-
cr ease the br
aking distance, with the re-
sulting risk of an accident.
