Warning
To avoid personal injury and/
or vehicle damage, always
disconnect the battery
before performing service
work on the hydraulic brake
system. Bleeding the brake
system with the battery
connected can lead to
excessive pressurization of
the system during automatic
diagnostic tests or diagnosis
of a leak or air in the braking
system. A Diagnostic
Trouble Code (DTC) may set
and vehicle speed may be
limited.
Brake Cooling (V-Series
Blackwing)
Prior to any track event, high
speed driving event,
or competitive driving,
complete the following:
1. Ensure all the brake
cooling parts are correctly
secured and installed.
2. Inspect and replace any
deflectors that have
damage.
3. Inspect for blockage in the
front brake cooling duct
prior to every event.
If improved brake cooling is
desired, install the ball joint
protector front shields,
remove both upper and lower
rear rotor shields, and install
the rear lower control arm
cooling deflectors, per the
instructions included with the
brake cooling kit. These parts
are for track use only. After
track events reinstall original
front and rear rotor shields,
and remove rear lower control
arm cooling deflectors.
