brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications .
At h igher speeds and with the w indshield w ipers
turned on, the brake pads press against the brake rotors for a sho rt amount of time. This occurs at
regular intervals without the driver noticing and
prov ides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likew ise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢,&. .
Due to their surface characteristics, ceram ic
brake rotors* absorb moisture in such conditions.
This can cause a temporary reduction in braking
force compared to dry brakes . You can compen ­
sate for this by press ing the brake pedal harder .
Corrosion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to form on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed¢& .
Fa ul ts i n the brake sys te m
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed¢&.
Low brak e flu id l eve l
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
monitored e lectronically.
Brake boo ste r
The brake booster increases the pressure that you
genera te with the brake pedal.

Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 218, Replacing wheels .
A WARNING ...__
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the initial 250 miles (400 kilometers) . The
break-in per iod can be cons iderably longer
for vehi cles w ith ceramic b rake rotors*. You
can compensate for this by p ress ing the
b rake peda l more fi rmly. This a lso applies
later when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
-
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance.
- Under certain cl imatic and operat ing condi­
tions such as passing t hrough water, dr iv ing
in heavy rain or after washing the veh icle,
the effect iveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fu lly apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.
