Technology
by pressing firmly on the brake pedal. Avoid
heavy braking during the break-in period.
Wear
Brake pad wear is largely dependent on the
way the vehicle is driven and on operating
conditions. This is especially true if you are
driving frequently in the city and on curves or
with a sporty driving style.
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi-
tions such as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight
condensation or after washing your car, the
braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be "dried" first with a few careful
brake applications.
At higher speeds and with the windshield wip-
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This action which is not felt by the driver hap-
pens at regular intervals and facilitates a bet-
ter reaction time for the brakes in wet weath-
er.
The braking effect can also be reduced if you
are driving on salted roads and you do not ap-
ply 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 ap-
plied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake ro-
tors and 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
Q
&..
Brake system malfunction
if you notice that the brake pedal travel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in-
creased pressure on the brake pedal will be
necessary.
Low brake fluid level
When the brake fluid level is low, malfunc-
tions in the brake system may occur. The
brake fluid level is electronically monitored .
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A
WARNING
-
- You should 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 descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving 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 diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa-
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
