CST system
CST is Ferrari’s acronym for Stability and
Traction Control. The CST is composed of
two main systems:
VDC
Vehicle Dynamics Control,
through the braking system;
ASR Vehicle Dynamics Control,
through the engine torque;
as well as the always active secondary
systems such as ABS, EBD, etc.
In order to have optimal control in different
driving and grip conditions, four different
setting levels have been designed.
Level 1 : ensures stability and maximum
traction on any type of roadway,
both in low-grip (“Low Grip”
position) and in very low grip
(ICE position) conditions, by
means of the engine and brake
control.
Level 2 : ensures stability and maximum
traction only in medium- to
high-grip conditions (SPORT
position), optimising engine and
brake control.
Level 3
: enhances the racing features of
the vehicle, ensuring (but not
in all conditions) a good level
of stability (RACE position) by
reducing engine control to a
minimum and making best use of
the brake control.
Level 4
: CST off (position )
Stability is not ensured, however,
all the other auxiliary systems,
such as the EBD and ABS, that
are always enabled in the other
positions, remain active (see page
133 ).
The driver will easily perceive enhanced
driving comfort (engine load limiting and
torque feedback), driving will be extremely
smooth, without jerks which could be
annoying and prevent the driver from fully
appreciating the potential of the vehicle.
Moreover, the several settings available
(depending on the level of grip) allow
driving at higher speeds, stability and easy
control, in any condition.
Braking system
The hydraulically-controlled braking
system is composed of ventilated disc
brakes on the four wheels, a “tandem”
vacuum brake servo and a hydraulic
control unit fitted with solenoid valves
and scavenge pump, which intervenes, if
the wheels lock, by adjusting the caliper
pressure (ABS).
The hydraulic circuits have crossed
branching and are independent for the
front and rear brakes. If one of the circuits
is faulty, emergency braking is always
possible with one circuit efficient.
The vacuum brake servo supplies the
hydraulic ECU with brake fluid at the
pressure required for system operation.
In the case of ABS activation, the solenoid
valves in the hydraulic ECU will activate,
with suitable adjusting cycles, in order to
prevent the wheels from locking.
Brake fluid tank
Positioned in the front compartment, it is
shared with the clutch system in vehicles
with mechanical gearbox.
Free play of the brake pedal
The maximum free play of the brake pedal
should be 8÷10 mm.
If it becomes excessive, or if one wheel
brakes more than the others, or if the
pedal feels spongy with reduced braking
efficiency, a complete inspection of the
