Brake system
Notes on the brake system
The brake system of your vehicle is designed for
heavy loads. Therefore, there may be noise when
braking. The loads in the entire brake system
which occur when driving on a racetrack are sig‐
nificantly greater than those during normal oper‐
ation.
The increased brake forces and temperatures
when driving on a racetrack inherently lead to
increased wear of the brake system.
Check the condition and geometry of the brake
cover plate before using the vehicle on a race‐
track.
Observe the information on the cooling of com‐
ponents which are subject to loads when oper‐
ated on a racetrack (
page 110).

Braking with ABS
Repeated hard braking within the ABS control
range causes higher temperatures in the brake
system than controlled braking shortly before
the ABS control limit.
Brakepad wear
The inner and outer brakepads may also suffer
"tapered wear". This could lead to poor pedal
feel. Therefore, you must also check the condi‐
tion of the brakepads before and after use on a
racetrack as part of a standard check for wear.
Brake discs
Observe the information on the cooling of com‐
ponents which are subject to strain in racetrack
operation (
page 110).

Depending on the vehicle's equipment, the AMG
ceramic high-performance composite braking
system is installed in your vehicle. The assess‐
ment of wear must therefore be carried out
using a special measurement procedure. The
brakes are measured using the current condition
of the ceramic composite material as a criteria
for assessing the wear instead of assessing the
residual thickness.
Depending on the type of brake disc, the follow‐
ing are combinations used to measure the wear
of the brake discs:
Carbon-ceramic brake disc:

Visual assessment of the brake disc for

mechanical damage
Wear measurement using the indicator

field method; alternatively using the Pro‐
ceq Carboteq
®
measuring device (e.g. in
the AMG Performance Center or at AMG
Trackdays)
Gray cast iron brake disc:

Crack test

Wear thickness test

The ventilation holes on gray cast iron friction
rings of standard brake discs in particular could
become blocked by brake dust. Therefore, check
the ventilation holes before using the vehicle on
a racetrack and clean them if necessary. If nec‐
essary, also clean the drilled holes.
Brake fluid
Check the following properties of the brake fluid
before each use on a racetrack:
Boiling point
R
Fill level
