224 DRIVING AND OPERATING
A message will display in the Driver
Information Center (DIC) when the
brake pads show excessive wear.
Brake Fluid
Replace existing brake fluid with a
qualified DOT 4 high performance
brake fluid from a sealed container.
Brake fluid with a dry boiling point
>310 °C (590 °F) is qualified. If high
performance brake fluid is used,
replace it with GM approved brake
fluid before driving on public roads.
If high performance brake fluid is in
the vehicle and the age of the brake
fluid is over a month old or unknown,
replace the brake fluid before track
events and competitive driving. Do
not use silicone or DOT 5 brake fluids.
It is critical to disconnect the battery
before bleeding the system, replacing
the pads, or any other work. The
battery must be disconnected to
prevent the brake master cylinder
from pressurizing the hydraulic
system during its automated self
diagnostic tests that can possibly
occur when a door is opened or the
remote key is present.Check the fluid level before each
competitive driving event.
Brake System Flushing & Bleeding
The J56 brake system requires specific
processes for bleeding and fluid
flushing. These can be found in the
service manual.
Properly bleeding the brake system is
required for proper operation of the
hydraulic brake system.
Brake Leak Detection
The hydraulic braking system has
advanced diagnostic capability to help
detect hydraulic leaks, trapped air,
and other performance issues. These
diagnostics are active when the
hydraulic system is powered. In order
to avoid inadvertently setting a leak
Diagnostic Trouble Code (DTC),
disconnect the battery before
servicing the brake system.
If the vehicle sets a DTC related to a
brake system leak, the Brake System
Warning Light will come on and
vehicle speed may be limited to 100
kph (62 mph). Any time a leak DTC is
set, the vehicle should be inspectedcarefully for evidence of a leak and
should be repaired immediately. See
your dealer.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
The Brake Fade Warning Assist
system is designed for use with the
factory-installed brake pads or GM
approved replacement pads. If the
brake pads on the vehicle need to be
replaced, use GM approved brake
pads. If this is not done, the brake
fade warning system may not function
properly.
Stage 1 :
The DIC displays a “Reduce
Braking to Avoid Overheating”
message, a chime sounds and brake
pedal effort and travel is increased.
When the message displays, the driver
should back up braking points and
reduce brake usage in order to reduce
brake temperature. This will allow for
continued lapping with no speed
limitations.

350 VEHICLE CARE
brake dust on the wheels and calipers
as compared to standard brake linings.
This is normal.
To help reduce squeal, high
performance brake pads are treated
with an anti-squeal paste that may
need to be reapplied periodically as
part of normal vehicle maintenance.
The anti-squeal paste will dissipate
over time. Also, the use of wheel
cleaners or power washers directly on
the brake calipers may remove the
anti-squeal paste from the brake pads.
It may be necessary to reapply the
anti-squeal paste if it is removed
during cleaning.
If brake squeal is excessive, the
anti-squeal paste should be reapplied.
The anti-squeal paste should always
be reapplied whenever the brake pads
are removed or replaced. See your
dealer for service.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if
there is a rapid increase in pedal
travel. This could be a sign that brake
service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement parts.
If this is not done, the brakes may not
work properly. The braking
performance can change in many
ways if the wrong brake parts are
installed or if parts are improperly
installed.
The Brake Fade Warning Assist
system is designed for use with the
factory-installed brake pads or GM
approved replacement pads. If the
brake pads on the vehicle need to be
replaced, use GM-approved brake
pads. If this is not done, the brake
fade warning system may not function
properly.
High Performance Brake Lining
Car Wash and Extended
Parking Care
If equipped with high performance
brake components, binding or
clunking may be noticeable after
extended parking or in cold weather
when the brakes have been wet, such
as when driving in the rain or after a
car wash. The clunking is normal forbrakes with high performance brake
linings and does not affect the
operation of the brakes. When driving,
normal braking will allow for the
brakes to feel smooth and the
clunking to go away. If the vehicle is
washed before overnight parking or
long term storage, drive it and apply
the brakes several times to thoroughly
dry the brakes.
Brake Rotor Wear (V-Series
Blackwing With J57 Carbon
Ceramic Rotors)
The V-Series Blackwing with J57 has
carbon ceramic brake rotors. The
rotors should be visually inspected
whenever the brake pads are replaced.
Carbon ceramic brake rotors also need
to be weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear-out
mass printed on the rotor. The rotor
can be reused if the weight of the
rotor is above the mass limit. Carbon
ceramic brake rotors inspection and
weighing methods can be found in the
service manual.

VEHICLE CARE 403
Caution
To avoid surface damage on wheels
and wheel trim, do not use strong
soaps, chemicals, abrasive polishes,
cleaners, or brushes. Use only GM
approved cleaners. Do not drive the
vehicle through an automatic car
wash that uses silicon carbide tire/
wheel cleaning brushes. Damage
could occur and the repairs would
not be covered by the vehicle
warranty.
Brake System
Visually inspect brake lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake
pads for wear and rotors for surface
condition. Inspect brake linings/shoes
for wear or cracks. Inspect all other
brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic. Applying
silicone grease on weatherstrips with a
clean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
Every six months, use plain water to
flush any corrosive materials from the
underbody. Take care to thoroughly
clean any areas where mud and other
debris can collect.
Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced.
Sheet Metal Damage
If the vehicle is damaged and requires
sheet metal repair or replacement,
make sure the body repair shop
applies anti-corrosion material to
parts repaired or replaced to restore
corrosion protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and
attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See
“Finish Care”previously in
this section.
