When  you are driving  at higher  speeds wit h 
the  windshield  wipers  on,  the  brake pads will  briefly  touch  the  brake d iscs in  regular  inter
vals so as to  improve  reaction  t ime when  brak
ing on wet  surfaces. You, the  driver,  will  not 
notice  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  brake discs and  pads with  a few  careful 
applications  of  the  brake  ¢ & . 
Cor ro sion 
There may be a tendency  for  dirt  to  build  up 
on the  brake pads and corrosion  to  form  on 
the  discs  if  the  car is not  dr iven regularly  or 
only  for  sho rt  trips  with  little  use of  the 
b rakes . 
If  the  brakes are not  used frequently,  or  if  cor rosion  has formed  on the  discs, it  is advisable 
to  clean 
off the  pads and discs by b rak ing 
fi rm ly a few  times  from  a mode rately  h igh 
speed ¢.& . 
Faults  in the  brake system 
If  you should  notice  a sudden increase in 
brake peda l travel,  t hen one of  the  two  brake 
circu its  may have  failed¢& . 
Low brake flu id le vel 
Malfunct ions can occur in the  brake system  if 
the  brake fl uid  level is too  low . T he brake fluid 
level  is monitored  electronically . 
Brake booste r 
The brake booster  increases the  pressure t hat 
you  generate  w ith  the  bra ke pedal.  It  on ly op
erates while  the  eng ine  is  running¢ &. 
Brake lining  wear  statu s 
Brake  lining  wea r may be c hecked by vis ual  in
spection  of  the  condition  of  the brake pads 
through  the  openings  in  the  whee l. If  neces 
sary, the  whee l may be removed  for  this  in
spection ¢

A WARNING 
-You should  perform  braking  maneuvers 
for  the  purpose  of  cleaning  the  brake 
system  only  if  road conditions  permit. 
Othe r road use rs must  not  be put  at  risk  -
you  may  ca use an accident! 
- Before descend ing a steep  grade,  reduce 
speed a nd s hift  transmission  into  a lower 
gea r o r l ower  dr iving  range.  Do  not  ride 
the  br akes or  ho ld t he pedal down  too 
long  o r too  often.  This could  cause  the 
brakes to  get  hot  and diminish  braking 
efficiency . 
- Do not  " ride the  brakes"  by rest ing you r 
foot  on the  pedal when you do not  intend 
to  brake. This may ca use the  brakes to 
overheat,  premature  wear  and  increased 
stopping  distance . 
- Under certain  cl imatic  and ope rat ing 
conditions  such as passing thro ugh wa
ter , dr iv ing  in heavy rain o r after  washing 
the  vehicle , the  effectiveness  of  the 
brakes can be  reduced . In  winte r, ice can 
accumu late  on the  bra ke pads, lin ings, 
d iscs a nd drum s. Carefu lly app ly bra ke s 
for  a test.  Brakes w ill dry  and ice co at
ings w ill be cleaned 
off after  a few  care
fu l brake applicat ions. 
- Driving  for  an exten ded period  o f time  o n 
salt -cove red roads without  using your 
brakes can a lso affect  braking  efficiency . 
C lean 
off accum ulated  salt  coating  from 
brake discs and  pads with  a few  careful 
brake applications. 
- I f you  damage the  front  spoiler,  o r if you 
install  a different  spoiler,  be sure the  air 
f low to  the  front  brakes is not  obstruct
ed. Otherw ise the  brak e system  could 
overheat  reducing  the  effectiveness  of 
the  entire  brake system. 
- Failure of  one b rake circuit  will  impai r 
the  braking  capab ility  result ing  in an  in
creased s topping  distance.  Avoid driving 
the  vehicle  a nd have  it  towed  to  the ne ar
est a uthorized  Audi  dea le r or  qu alified 
wo rkshop.
