2016 AUDI S4 brake rotor

Intelligent Technology
Braking
What affects braking efficiency?
New brake pads
During the firs t 25 0 miles (400 km), new b rake
pads do not possess their full braking effect , they
have to be "broken i n" first ¢& . You can com­
pensate for this slight ly reduced braking power
by push ing harder on the brake pedal. Avoid
heavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles a re still sub ­
ject to wear, depend ing largely on ope rating con ­
ditions and driving habits¢& . On vehicles that
are either dr iven most ly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by you r authorized Aud i dea ler more of­
ten than spec ified in the
Warranty & Mainte­
nance booklet .
Failu re to have your brake pads
i n spected c an resu lt in reduced bra ke pe rform­
ance.
O n steep slopes, you sho uld use the braking ef ­
fect of the eng ine . This way, you prevent unnec­
es sary wear on t he b rake system. If yo u m ust use
your b rake s, d o not hold the brakes down cont in­
uously. Pum p th e b rakes at intervals.
Operating noise
Noises may occur when brak ing depend ing on the
speed, b raking force and outs ide cond it ions such
as tempe ra tu re and humidi ty.
Effect of water and road salt
In certain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the b raking
effect can be reduced by mo isture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake a pplica tions.
At highe r speeds and with t he windsh ield wipers
tur ned on, the br ake pads press aga inst the brake
rotors for a sho rt amoun t of time. This occur s at
regular intervals w it h out t he dr iver noticing and
p rov ides for better bra ke response time under
wet conditions.
180
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and t he b rakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few caut ious app lications of the
brake ¢& .
Corrosi on
There may be a tendency fo r dirt to build up on
the b rake pads and corrosion to form on the discs
i f the car is not driven regu larly or only for short
trips with little use of the brakes .
If the bra kes are not used frequent ly, or if corro­
s ion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ &.
Faults in th e brake system
If you shou ld notice a sudden increase in brake
pedal travel , then one of t he two brake circu its
may have failed¢& .
Low brake fluid level
Malfu nctions can occu r in the brake system if the
br ake fluid level is too low . The brake fluid leve l
is mo nitored electronica lly .
Brake booster
The bra ke booster i ncreases the press ure t hat
yo u ge nera te with the brake ped al.
It works only
whe n the eng ine is ru nning .¢ &
Brake lining wear status
Brake lining wea r may be c hecked by visua l in­
spection o f the condition of the brake pads
t hr ough t he openings in t he wheel. If necessary,
t h e wheel m ay be removed fo r thi s inspe ction
¢ page 240, Replacing wheel s.
_& WARNING
- New brake pads don't have the be st sto p­
ping power and m ust be " broken-in" du ring
the initial 250 miles (400 kilometers). You
can compensate for this by p ressing the
brake pedal more firmly. This also app lies
later w hen new pads are installed.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1 ,000 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any c ircumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
sca le
c=>page 10.
During the first few hours of driving, the eng ine's
internal friction is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).
(D Note
Extremely high eng ine speeds a re au toma ti­
cally reduced. However, these rpm limits are
programme d for a n engine well run-in, not a
new engine.
@) For the sake of the environment
D o not dr ive with u nnecessari ly high eng in e
spee ds -ups hifting ea rly saves fuel, reduces
noise and pro tec ts the envi ronme nt.
Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking.
Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem
parts do no t bottom o ut and get dama ged.
T his is espec ially true for ve hicles with low-s lung
c h ass is (sports c hass is) * and fully loaded
vehicles.
Driving through water on
roads
Note t he following to avoi d ve hicle damage w hen
driv ing through water, for examp le on flooded
roads:
- The water must not be any hig her t han the bot ­
tom of the vehicle body.
- Do not dr ive faste r than walk ing speed.
A WARNING
= -
Afte r driv ing th ro ugh water, m ud, slush, etc .,
the brakes may be slow to take effect beca use
of wet brake rotors and pa ds. Dry the brakes
f irst by braking carefully to restore the full
b raking effect.
(D Note
Ve hicle compone nts such as the engine,
transmission, suspension o r electrica l system
can be severely damaged by driving throug h
water.

Care and cleaning
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
ing the underbody or the inside of the wheel
housings.
- A fter washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice i n the winter. The brakes
must be dried first w it h a few careful brake
applications.
{U) Note
- If you wash the ve hicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in and out us ing the power folding
f u nct io n.
- T o p revent paint damage, do not wash the
vehicle in di rect sunlight. -
To red uce the risk of damage to the s urface,
do not use insect removing sponges, k itchen
sponges o r similar items .
- Matte finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Neve r use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash t he veh icle in facili ties spec ially de­
s igned for that pu rpose. This will reduce the
r isk of dirty wate r cont am ina ted with o il from
en te ring the sewe r system.

sc rewdrive r hand le to loose n or tig hten the
wheel bol ts .
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a t read pattern in­
tended for use in a specif ic direction, please note
the following:
- The direction of rotation is marked by an
arrow
on the side of the tire.
- If the spare tire has to be inst alled in the inco r­
rect direction, use the spare tire on ly tempora ­
r il y since the tire will not be a ble to ac hieve its
optimum performance characterist ics with re­
gard to aquaplan ing, no ise and wear.
- We recommend that you pay part icu lar atten­
tion to th is fact d uring wet weather and that
you adjust your speed to matc h road condi­
tions .
- Rep lace the flat tire w ith a new one and have it
installed o n your veh icle as soon as possib le to
restore the hand ling advan tages of a un id irec­
t ional tire.
Notes on wheel changing
Please re ad th e inf ormati on ¢ page 224, New
t ires or w heels
if yo u are going to use a sp are tire
which is d iffe rent from the t ires on your ve hicle.
Af ter yo u cha nge a tire :
-Check the tire pressure on the spare immedi­
ately after installation .
- Have the wheel bolt t ightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
