constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads
If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes, when brak-
ing for the first time. You must brake harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. This
way the brake discs will become warm, drying
more quickly, which will protect them against
corrosion.
Limited braking performance on salted
roads
G Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in
the braking effect, resulting in a signifi-
cantly longer braking distance, which could
lead to an accident.
To avoid this danger, you should:
occasionally brake carefully, without put-
R
ting other road users at risk, when you
are driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
maintain a greater distance to the vehicle
R
ahead and drive with particular care.
carefully apply the brakes at the end of a
R
trip and immediately after commencing a
new trip, so that salt residues are
removed from the brake disc.
New brake pads/linings
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle that have been approved
for Mercedes-Benz vehicles or which corre-
spond to an equivalent quality standard.
Brake pads/linings which have not been
approved for Mercedes-Benz or which are not
of an equivalent quality could affect your vehi-
cle's operating safety.
G Risk of accident
New brake pads/linings only reach their
optimum braking effect after several hun-
dred kilometres of driving. Before this opti-
mum braking effect is reached, you should
compensate for the reduced braking effect
by applying greater pressure when braking.
This also applies after the brake discs or the
brake pads/linings have been replaced.
High-performance brake system for
AMG vehicles
The high-performance brake system is
designed for heavy loads. Braking can there-
fore cause noises. This will depend on:
speed
R
braking force
R
environmental conditions, such as temper-
R
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
