mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that havebeena pproved by
Mercedes-Benz
Rbrake pads/lining sthat hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/lining scan
compromise the safety of your vehicle.
Alway sreplace al lbrake disks and brake pads/
linings on an axl eatthe sam etime. Always
install new brake pads/lining swhenr eplacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connectio nismatched.
The use of brake disks other than those
approved by Mercedes-Benz can chang ethe
track width and is subject to approval ,ifappli-
cable.
Shock-typ eloads whe nhandling the brake
discs, such as whe nchanging wheels ,can lead
to areduction in comfortw hend riving with light-
weigh tbrake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that yo uonly use
brake fluid that has bee nspeciall yapproved for

equivalent quality could affect your vehicle's
operating safety.
High-performance and ceramic brakes
(Mercedes AMG vehicles)
The AMG brake systems are designe dfor heavy
loads. Thism ay leadtonoisew henb raking. This
will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
ture and humidity
The wear of individua lcomponents of the brake
system, such as the brake pads/lining sorbrake
discs, depends on the individua ldriving style
and operating conditions.
For this reason, it is impossible to state amile-
ag ethat will be valid under al lcircumstances. An aggressive driving styl
ewilll ea dtoh ighw ear.
You can obtain more information on this from a
qualified specialist workshop.
New and replaced brake pads and discs only
reach thei roptimum braking effect afte rseveral
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Kee pthis in mind ,and adap tyou rd riving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingl yhighb rake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake statu smessages in the multifunction
display. Especiall yfor hig hperformance driving,
it is important to maintain and hav ethe brake
system checked regularly.
