battery must be disconnected to
prevent the brake master cylinder
from pressurizing the hydraulic
system during its automated self
diagnostic tests that may occur when
a door is opened or the remote key is
present.

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.
