intervals and ensures a better reaction time fo r
the brakes in wet weather.
The braki ng 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
f irst when the brakes are applied.
Due to its surface, the ceramic bra ke rotor* ab-
sorbs moisture in certa in situations. Theref ore,
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 fo r long periods of
time, low mi leage 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 malfunct ion
if you notice t hat the brake pedal travel has sud-
denly increased, then a brake circuit in t he 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 w ill
need a longer distance to stop and you w ill need
to press the brake pedal harde r.
Low brake fluid level
When the brake fl uid level is low, malfunct ions in
the brake system may occur . The brake f luid 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
- Only apply the brakes for the purpose of
cleaning the brake system whe n 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 the ir f ull
braking effect during the first 250 m i
(400 km). They must be "broken in" first.
The break-in period can be considerably lon-
ger fo r vehicles with ceram ic brake rotors* .
However, you can compensate fo r the
slightly reduced braking force by pressi ng
fi rm ly on the brake pedal. Avoid heavy brak-
ing du ring the break-in period.
- Cert ain weathe r and operating condit ions
such as driving through water, dr iving in
heavy rain or driv ing after washing your ve-
hicle can impa ir the effect iveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefully. Ap-
plyi ng the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im-
paired by dr iving for long stretches on roads
covered with salt without using the bra kes.
You can remove salt deposits from the
brake rotors and pads by carefully applying
t he brakes several times .
- If the fron t spoiler is damaged or you install
another spoi ler, make sure the fr ont wheel
brakes are vent ilated properly . Otherwise,
the brake system could overheat, which re-
duces their effectiveness .
- Fail ure of a brake circuit impairs brak ing
performance, which increases braking dis-
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
deale r or authorized Aud i Service Facility.
- If the brake booster is not working, yo u w ill
have to press much harder on the brake
pedal to compensate fo r the lack of the
booster.
Q) Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
