intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Due to its surface, the ceramic brake rotor* ab
sorbs moisture in certain situations. Therefore,
there will temporarily be less braking force than
when the brakes are dry. You can compensate for
this by pressing the brake pedal harder.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and
pads ¢.&. .
Brake system malfunction
If you notice that the brake pedal travel has sud
denly increased, then a brake circuit in the dual
circuit brake system may have malfunctioned. Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder .
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap
ply to the brake pedal. It only works when the en
gine is running.
A WARNING

cleaning the brake system when road and

traffic conditions permit. You must not en
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km) . They must be "broken in" first.
The break-in period can be considerably lon
ger for vehicles with ceramic brake rotors*.
However, you can compensate for the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak
ing during the break-in period.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your ve
hicle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly. Otherwise,
the brake system could overheat, which re
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility.
- If the brake booster is not working, you will
have to press much harder on the brake
pedal to compensate for the lack of the
booster .

pedal lightly when braking is not actually
