2020 MERCEDES-BENZ AMG GT COUPE brake pads

R
allow the engine toreach a maximum engine
speed of 4,500 rpm on lybrief ly.
R drive theve hicle in drive program A.
R change gear before there v counter needle is
Ô ofthewa yto there d area of there v coun‐
te r.
R do not shift down a gear manually in order to
brake.
R avoidoverstra ining theve hicle, e.g. driving at
full thro ttle.
R do not depress the accelera tor pedal past
th e pressure point (kickdown).
R only increase the engine speed gradually and
accelera tetheve hicle tofull speed af ter
1, 500 km.
This also applies when the engine or parts of the
driv etra in ha vebeen replaced.
Please also obser vethefo llowing running-in
no tes:
R in cer tain driving and driving saf ety sy stems,
th e sensors adjust automatically while a cer‐
ta in dis tance is being driven af terth eve hicle
has been delivered or af terre pairs. Full sys‐ te
m ef fectiveness is not reached until the
end of this teach-in process.
R brakepads, brake discs and tyres that are
either new or ha vebeen replaced only ach‐
ie ve optimum braking ef fect and grip af ter
se veral hundred kilom etre s of driving. Com‐
pensate forth ere duced braking ef fect by
applying greaterfo rc eto the brake pedal. Note
s on engine output and engine torq ue %
The actual (maximum) values that can be
achie vedfo r engine output and engine tor‐
qu e may deviate from the certified values
within the count ry-specific guidelines for
permissible tolerances (basis: UN-ECE No.
85 or country -specific guidelines).
Fa ctors that can influence this are, forex am‐
ple:
R sea le vel
R fuel grade
R outside temp erature
R operating temp erature of the engine Unti
lth e engine has reached its operating tem‐
perature, thefo llowing engine operating temp er‐
ature warning lamp is lit: Engine output and engine
torque ha vebeen
re duced. Take this into account foryo ur driving
st yle.
When the engine operating temp erature warning
lamp goes out, full engine output and engine tor‐
qu e are available. Note
s on driving &
WARNING Risk of accident due to
objects in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tr avel or block a depressed pedal.
This jeopardises the operating and road
saf ety of theve hicle. Driving and parking
103

Therefore, obser
vethefo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerably orresult in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts R
avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page315).
Note s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wate r:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at most, otherwise
wate r can enter theve hicle interior or engine
compartment.
R Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention toth
e traf fic conditions until braking po wer has
been fully restored. Fu
nction of rear axle steering The
rear axle steering is an electromechanical
auxiliary steering on there ar axle which adjusts
th esteering of there ar wheels according tothe
position of the front wheels, depending on the
speed. This results in greater manoeuvrability
and impr ovedstabilit y.
Re ar axle steering has thefo llowing characteris‐
tics:
R reduced steering ef fort and turning circle
re sulting in reduced parking ef fort
R impr oved driving stabilit y,e.g. when corner‐
ing
R more direct steering resulting in impr oved
handling of theve hicle
Obser vethe no tes on snow chains
(/ page 315) and on activating snow chain
mode. 106
Driving and pa rking

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.
