General information
What affects braking efficiency?
Operating condi tions and d riv ing hab it s
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat­
ing conditions and driving habits
c:> A . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the brake pads should be checked by your author­
i zed Audi dealer more often than specified in
the
Warr ant y & Maint enan ce bookle t. Failure
to have your b rake pads inspected can res ult
i n red uced brake performance.
On steep slopes, you should use the brak ing
effect of the engine. This way, you prevent un­
necessa ry wea r on the brake system.
If you
must use yo ur brakes, do not ho ld the brakes
down continuously. Pump the brakes at inter ­
va ls.
Moistu re or road salt
Unde r ce rtain conditions, for example, when
driving through wate r or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced d ue to moisture (or in
freezing conditions ice) on the brake pads . A
few careful brake app lications should dry
off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake discs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces . You the driver w ill not no­
tice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too,
you should clean
off accumulated salt coat ing
from b rake discs and pads with a few careful
applications of the brake

There may be a tendency for dirt to build up
on the brake pads and corrosion to form on

the d iscs if the car is not driven regu larly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion has formed on the discs, it is adv isable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed

Fault s in the brak e syste m
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
circuits may have fai led ¢
A.
Low brake fluid lev el
Malfunctions can occu r in the bra ke system if
the brake fluid level is too low. The brake flu id
level is monitored elect ronica lly.
Brake booster
The brake booster works with vacuum pres­
su re which is created only whe n the engine is
runn ing ¢,&. .
Brake lining we ar s tatus
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed fo r thi s in­
spection ¢

_& 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 ca use an accident!
- Before descending 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 . Th is could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
