The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
WARNING
■
Greater physical effort is required for braking when the engine is switch-
ed off – there is the risk of an accident.
The clutch pedal must be depressed when braking on a vehicle with man-
Under these severe conditions, the thickness of the brake pads must also be
checked by a specialist garage between services.
■
ual transmission, when the vehicle is in gear and at low revs. If you fail to
do so, the functionality of the brake servo can be impaired – there is the
risk of an accident.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times.
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
The front brakes may overheat, which can have a negative impact on the
functioning of the braking system – there is a risk of an accident.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned and dried by applying the brakes several times.
■
When leaving the vehicle, never leave persons who might, for example,
release the handbrake or take the vehicle out of gear unattended in the ve-
hicle. The vehicle might then move off – there is the risk of an accident.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
CAUTION
■
■
Observe the recommendations on the new brake pads » page 109.
Never let the brakes slip with light pressure on the pedal if braking is not
necessary. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately as you will not know how great the damage is.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 36, Brake sys-
tem.
Information for braking
Read and observe and on page 103 first.
Brake booster
If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
Before travelling a long distance down a steep gradient, reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. Any additional braking should be
completed intermittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
