Brake sy
stem Note
s onthe brake sy stem
The brake sy stem of your vehicle is designed for
heavy loads. Therefore, there may be noise when
braking. The loads in the entire brake sy stem
which occur when driving on a racetrack are sig‐
nificantly grea terth an those during normal oper‐
ation.
The increased brake forc es and temp eratures
when driving on a racetrack inhe rently lead to
inc reased wear of the brake sy stem.
Check the condition and geometry of the brake
co ver plate before using theve hicle on a race‐
trac k.
Obser vethe information on the cooling of com‐
ponents which are subject tostra in when oper‐
ated on a racetrack (/ page 109).
Braking with ABS
Re peated hard braking within the ABS control
ra nge causes higher temp eratures in the brake
sy stem than controlled braking shortly before
th e ABS control limit. Brakepad
wear
The inner and outer brakepads may also suf fer
"tapered wear". This could lead topoor pedal
fe el. Therefore, you must also check the condi‐
tion of the brakepads before and af ter use on a
ra cetrack as part of astandard check forwe ar.
Brake discs
Obse rveth e information on the cooling of com‐
ponents which are subject tostra in in racetrack
ope ration (/ page 109).
Depending on theve hicle's equipment, the AMG
ceramic high-per form ance composite braking
sy stem is fitted in your vehicle. The assessment
of we ar must therefore be car ried out using a
special measurement procedure. The brakes are
measured using the cur rent condition of the
ceramic composite material as a criteria for
assessing thewe ar ins tead of assessing the
re sidual thickness.
Depending on the type of brake disc, thefo llow‐
ing are combinations used tomeasu rethewe ar
of the brake discs:
R Carbon-ceramic brake disc -
Visual assessment of the brake disc for
mechanical dama ge
- Wear measurement using the indicator
fi eld me thod; alternatively using the Pro‐
ceq Carbo teq®
measu ring device (e.g. in
th e AMG Performance Center or at AMG
Tr ackda ys)
R Grey cast iron brake disc
- Visual check
- Crack test
- Wearthickness test
The ventilation holes on gr eycast iron friction
ri ngs of standard brake discs in particular could
become bloc kedby brake dust. Therefore, check
th eve ntilation holes be fore using theve hicle on
a ra cetrack and clean them if necessar y.If nec‐
essar y,also clean the drilled holes.
Brake fluid
Che ckthefo llowing properties of the brake fluid
before each use on a racetrack:
R Boiling point
R Fill le vel 11 0
Driving and pa rking

When driving on a
racetrac k,make sure that the
brake fluid is not more than 12 months old.
Brake callipers, brake hoses and brake lines
Check thefo llowing for dama geeach time
before driving theve hicle on a racetrack:
R The du stboots on the brake callipers
R The brake hoses and brake lines
Re place them if necessar y.
Brake cooling
Special air deflectors and channels are fitted to
th e front and rear axles so that the brakes are
cooled suf ficiently. They supply the brake disks
with cooling air. Check that they are in per fect
condition and cor rectly fitted ea chtime be fore
driving theve hicle on a racetrac k.Excessi ve
we ar can be caused bydriving overke rbs, for
ins tance. Forth is reason, regularly check they
are all comple teand fitted securely.
In addition, check that the air guide plates are
seated securely and clean before and af ter driv‐
ing theve hicle on a racetrac k. Obser

ponents which are subject tostra in in when driv‐
