Foot Brake - Volvo V70 Owner's Manual

General
The car is equipped with two brake circuits. If
one brake circuit is damaged then this will
mean that the brakes engage at a deeper level
and harder pressure on the pedal is needed to
produce the normal braking effect.
The driver's brake pedal pressure is reinforced
by a brake servo.
WARNING
The brake servo only works when the engine
is running.
If the brake is used when the engine is switched
off then the pedal will feel stiff and more force
must be used to brake the car.
In very hilly terrain or when driving with a heavy
load the brakes can be relieved by using engine
braking. Engine braking is most efficiently used
if the same gear is used downhill as up.
For more general information on heavy loads
on the car, see page 275.
Anti-lock braking system
The car is equipped with ABS (Anti-lock
Braking System) which prevents the wheels
from locking during braking. This means the
ability to steer is maintained and it is easier to
swerve to avoid a hazard for example. Vibration
may be felt in the brake pedal when this is
engaged and this is normal.
A short test of the ABS system is made auto-
matically after the engine has been started
when the driver releases the brake pedal. A
further automatic test of the ABS system may
be made when the car reaches 40 km/h. The
test may be experienced as pulses in the brake
pedal.
Cleaning the brake discs
Coatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimised by cleaning the brake linings.
Manual cleaning is advisable with wet road
surfaces, prior to long-stay parking and after
the car has been washed. Carry this out by
braking gently during a short period while en
route.
Emergency Brake Assistance
Emergency Brake Assistance EBA (Emergency
Brake Assistance) helps to increase brake
force and so reduce braking distance. The EBA
system detects the driver's braking style and
increases brake force as necessary. The brake
force can be reinforced up to the level when the
ABS system is engaged. The EBA function is
interrupted when the pressure on the brake
pedal is reduced.

NOTE
When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.
Symbols in the combined instrument
panel
Symbol Specification
Constant glow – Check the
brake fluid level. If the level is
low, fill with brake fluid and
check for the cause of the brake
fluid loss.
Constant glow for 2 seconds
when the engine is started –
There was a fault in the brake
system's ABS function when
the engine was last running.
