Brakes, 4-Wheel Disc; Electric Power-Assisted Steering (Epas); Drift Control; Selectable-Effort - Ford Mustang 2012 User Manual

Large 4-wheel Disc Brakes
• Dual-piston front brake calipers provide excellent
pedal feel with low effort
• Mustang GT vented front discs are 13.2" in diameter
• Front discs are 1.42" thick and ventilated to help
air cooling and provide consistent fade-free
stopping power
• Mustang V6 vented front discs are 12.4" in diameter
• V6 and GT use single-piston rear calipers clamping
down on 11.8" vented discs that are 0.75" thick
• Disc brakes provide low-effort stopping power and
are more resistant to fade than drum brakes
NOTE: See page 19 for
Boss 302-specific brake
system features.

Active Nibble Control
What Is Nibble?
• Steering nibble is undesirable rotational vibration
that can be felt through the steering wheel – mostly
when the vehicle is traveling straight
• Nibbles are often caused by the presence of an
out-of-balance front wheel/tire, or "brake shudder,"
often caused by unequal wear of the brake rotors
How Active Nibble Control Works
• Torque sensors located in the electric motor
sense nibble vibrations
• The electric motor then applies a counter-
rotational force to cancel out the vibrations
• This counter-rotational force helps reduce
unwanted vibrations in the steering wheel
Key Benefits
• EPAS system sensors continuously monitor
steering wheel inputs
• When sensors detect steering wheel rotational
vibrations — or nibbles — EPAS counteracts the
nibbles and seamlessly cancels them out
• Helps reduce the amount of minor steering
corrections caused by the steering nibbles
and helps provide a more comfortable
driving experience

Electric Power-Assisted Steering (EPAS) with
Driver-selectable Effort, Drift Control and
Active Nibble Control
Key Benefits
• Class-exclusive
• EPAS is a sophisticated electric speed-sensitive
steering assist system
• Offers light, responsive steering around town and
for parking
• At higher speeds, EPAS delivers less steering assist
for more confident control
• EPAS replaces the hydraulic gear system that pulled
power (and efficiency) from the engine via a belt
• Helps improve fuel economy and eliminate hydraulic
noises common with hydraulic systems
Driver-selectable Effort Power-assisted
• New feature to Mustang for 2012, standard on
all models
• Offers customer choice of three settings
– Comfort Mode provides the least amount of road
– Sport Mode provides the most road force felt
– Standard Mode is a balance between the Comfort
• Steering effort is locked in Sport Mode when
AdvanceTrac Sport Mode is on; learn more about
AdvanceTrac Sport Mode on page 16
• Settings are accessed and programmed via the
Message Center

Drift Control

• An automatic system that uses EPAS to help
continuously correct for road irregularities and
improve overall steering feel
• System is continually "learning" and adapting to
steering conditions and compensates for changes
that can cause the vehicle to pull left or right
– Assists the steering effort to help the driver
– Helps driver avoid unwanted lane changes
• Reduces steering effort required when driving on
crowned roads or in heavy side winds
