Ferrari Service Network.
Brake pads
The brake pads are fitted with a wear
indicator that is connected to the brake
warning light. When this warning light
comes on or, in any case, whenever braking
no longer appears to be regular, the pad
thickness and the condition of the braking
surfaces must be checked.
The minimum thickness allowed for the
pads is 3 mm (thickness of the friction
material only).
The brake failure warning light will come
on to indicate excessive wear of the brake
pads, which must be replaced immediately.
If you have the brake pads replaced
at an unauthorised workshop
Ferrari is relieved of all responsibility for
damage caused to persons or things.
In order to allow the pads to bed in following
replacement, avoid sudden and sharp braking
until they have fully adapted (after about 300
km).
ABS and EBD systems
The vehicle is equipped with ABS (Anti-
Lock Braking System) and EBD (Electronic
Brake-Force Distribution) systems which,
by means of the ECU and the ABS sensors,
enhance the performance of the braking
system.
In the event of an emergency stop or
braking on slippery surfaces (e.g., where
there is snow, ice, etc.), the ABS together
with the conventional braking system
allow applying the maximum braking
force without the wheels locking and
consequently losing control of the vehicle.
The system is based on an electronic
control unit that processes the signals
coming from 4 sensors integrated in the
circuits of the 4 wheels.
When a wheel tends to lock, the sensor
warns the ECU which, in its turn, signals
to the electro-hydraulic unit to intervene
and modulate the pressure on the brake
calipers. The driver will perceive a 'pulsing'
sensation coming from the brake pedal,
which is normal.
In the event of a failure, the system will
be deactivated, but this will not affect the
efficiency of the conventional braking
system.
The failure is indicated by the relative
warning light on the instrument panel
coming on. In this case it is advisable
to contact the nearest workshop of the
6 - Technical Information
Ferrari Service Network who will
immediately identify the fault thanks to
the self-diagnostic function with which the
system is equipped.
The system performance in terms of active
safety must not allow the driver to take
unnecessary and unjustified risks.
The driving style shall always be suited to
weather conditions, range of visibility and
road traffic conditions.
The maximum deceleration obtainable is
however always dependent on the tyre grip
on the road. Obviously, when there is snow
or ice on the road, grip is greatly reduced
and therefore the braking distance is
greater even if the ABS system is active.
The vehicles must be fitted with wheel
rims, tyres and brake lining of the type
and make approved for this model by the
Manufacturer.
Although this device greatly contributes
to the vehicle's safety, it is still essential to
drive with particular care when the road is
wet or there is snow or ice.
The vehicle is equipped with an EBD
(Electronic Brake-force Distribution)
system.
If the warning light comes on when the
engine is running, it indicates a malfunction
of the EBD system. In this case, sharp
braking could lead to the rear wheels
locking too early and the vehicle may skid.
