Brakes
Battery Disconnect
Disconnect the battery before servicing the
hydraulic brake system. 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.
{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 Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 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.
Check the fluid level before each competitive
driving event.
Brake System Flushing & Bleeding
The J55 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
inspected carefully 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

4. Apply the brakes 25 times from100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applications.
As with all high performance brake systems,
some amount of brake squeal is normal.
Alternative Closed Course Brake Burnishing
Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
This procedure should only be run on a
track and only on dry pavement. Brake
pedal fade will occur during this track
burnish procedure and can cause brake pedal
travel and force to increase. This could
extend stopping distance until the brakes
are fully burnished. 1. Start track lapping at lower speeds and lower braking efforts for three minutes
of driving. Allow for increased braking
distances due to reduced brake output. 2. After Step 1, increase speed and braking
effort for the next six minutes of
lapping, gradually ending up at 90%
effort. Continue to allow for increased
braking distance due to reduced brake
output.
3. Cool the brakes by lapping with minimal light braking for six minutes.
Brake Cooling Kit
Prior to any track event, high speed driving
event, or competitive driving, the following
should be completed:
.Ensure all brake cooling parts are
correctly and securely installed.
.Install the rear lower control arm cooling
ducts per the instructions below also
included with the kit. After any track
event or competitive driving, remove the
rear lower control arm cooling ducts.
These parts are for track use only.
Removing the ducts helps prevent debris
from being channeled into the rear brakes
during regular use of the vehicle.
.Inspect for and remove any blockage in
the ducts.
.Inspect and replace any duct that has
damage.

other cargo. Inflate the front tires to 159 kPa
(23 psi) and the rear tires to 165 kPa (24 psi).
Drive at a maximum speed of 296 km/h
(184 mph).
Road Course target hot pressures of
220–240 kPa (32–35 psi). Value will vary
based on driving style, track, temperature,
and weather conditions.
Wheel AlignmentCaution
Using these wheel alignment settings
may cause excessive tire wear. Only use
these wheel alignment settings for racing
or competitive driving. Excessive tire wear
is not covered under the vehicle
warranty.
Caution
Do not use power tools when removing
or installing the fasteners. Damage to the
threads may occur. Use hand tools only,

and do not overtighten. Hand start the
fasteners to ensure that the threads do
not bind or cross thread.
The racing and competitive driving wheel
alignment settings should be set as
described here.
To achieve the track alignment specified
settings: 1. The upper control arm to body washers on all four corners will need to be
moved from between the body and the
control arm and relocated between the
head of the bolt and the control arm.
2. Adjust the lower control arm cam bolt position to achieve the following
specifications.
Front (per corner)
.Caster: +8.0 degrees
.Camber: -3.0 degrees
.Toe (total): 0.1 degrees toe in
Rear (per corner)
.Caster: 0 degrees
.Camber: -2.5 degrees
.Toe (total): 0.1 degrees toe in
.Thrust Angle: 0 degrees
After track use, reinstall washers between
the body and the control arms. Reset to
factory alignment settings. See your dealer.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other (Continued)

Stopping the Engine/OFF (No Indicator
Lights) :When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power (RAP)
will remain active. See Retained Accessory
Power (RAP) 0193.
If the vehicle is in R (Reverse), D (Drive),
or M (Manual Mode), the vehicle will shift
to P (Park), the ignition will turn off, and
RAP will remain active.
If the vehicle is in N (Neutral), the ignition
will return to ACC/ACCESSORY and display
the message SHIFT TO PARK in the Driver
Information Center (DIC). When the vehicle
is shifted into P (Park), the ignition will
turn off.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.
If the vehicle must be turned off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force. 2. Shift into N (Neutral). This can be done
while the vehicle is moving. After
shifting into N (Neutral), firmly apply the
brakes and steer the vehicle to a safe
location.
3. Come to a complete stop. Shift into P (Park).
4. Set the parking brake. See Electric
Parking Brake 0203. Press ENGINE
START/STOP to turn the vehicle off.
{Warning

airbags. While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over and
must be turned off while driving, press and
hold ENGINE START/STOP for more than
two seconds, or press twice within
five seconds.
ACC/ACCESSORY (Amber Indicator Light) :
This mode allows the use of some electrical
accessories when the engine is off. With the ignition off, pressing the button
one time without the brake pedal applied
will place the ignition in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to off after five minutes to
prevent battery rundown.
ON/RUN/START (Green Indicator Light) :
This
mode is for driving and starting. With the
ignition off and the brake pedal applied,
pressing the button once will place the
ignition in ON/RUN/START. Once engine

rate of launch. Tire spin may occur with the
accelerator pedal pressed and the Traction
Control System (TCS) turned off.
This launch occurs when both of these
conditions are met:
.Vehicle speed is below 10 km/h (6 mph).
.Both the + paddle and−paddle are
released at the same time.
With the accelerator fully pressed and the
engine at the rev limiter, peak performance
only occurs if the paddles are released
within a short period of time after reaching
the rev limit (i.e., a few seconds).
Applying the brakes while the tires are
spinning may result in the clutch releasing.
Standard Exit : Engine power is reapplied to
the wheels gently to support normal vehicle
operation on public roads.
This occurs when paddles are released under
any of the these conditions:
.Vehicle speed is above 10 km/h (6 mph).
.The vehicle is in R (Reverse).
.The + paddle and −paddle are not
released at the same time. If the vehicle was in Temporary Manual
Paddle Shift mode before entering Double
Paddle Declutch, the vehicle will return to D
(Drive) with automatic shifting upon exiting
Double Paddle Declutch.
{Warning
When exiting Double Paddle Declutch, the
vehicle may move rapidly. You could lose
control and cause a crash with nearby
people or objects. Be ready to release the
accelerator pedal or apply the brakes
immediately if the vehicle moves too
quickly. Do not use the Double Paddle
Declutch when people or objects are near.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake
pedal is applied during normal operation.
The system performs routine tests and turns
off within a few minutes after the vehicle is
turned off. Noise may be heard during this
time. If the brake pedal is pressed during the tests or when the electric brake boost
system is off, a noticeable change in pedal
force and travel may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
If there is a problem with ABS, this warning
light stays on. See
Antilock Brake System
(ABS) Warning Light 089.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.

Driving and Operating 203
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing and feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPBcannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. See
Electric Parking Brake
Light 089 and
Service Electric Parking Brake Light 089.
There are also parking brake-related Driver
Information Center (DIC) messages.
Before leaving the vehicle, check the red
parking brake status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake status light
flashes continuously, then the EPB is only
partially applied or there is a problem with
the EPB. A DIC message will display. Release
the EPB and try to apply it again. If the
light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the amber service parking brake warning
light is on, press the EPB switch. Continue to
hold the switch until the red parking brake
status light remains on. If the amber service
parking brake warning light is on, see your
dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or at the request of other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.

EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red parking
brake status light is off.
If the amber service parking brake warning
light is on, release the EPB by pressing and
holding the EPB switch. Continue to hold the
switch until the red parking brake status
light is off. If either light stays on after
release is attempted, see your dealer.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if the
vehicle is running, placed into gear, and an
attempt is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when (Continued)
Warning (Continued)
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 175.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.

Ride Control Systems
Traction Control/Electronic
Stability Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak/Electronic
Stability Control (ESC) system. These
systems help limit wheel spin and assist the
driver in maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the rear
wheels are spinning too much or are
beginning to lose traction. When this
happens, TCS applies the brakes to the
spinning wheel and reduces engine power
(by closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.If cruise control is being used when TCS
begins to limit wheel spin, the cruise control
will automatically disengage. Cruise control
may be reengaged when road conditions
allow. See
Cruise Control 0216.
If the driver disables TCS, cruise control will
disengage. Cruise control will also be
disabled if Performance Traction
Management (PTM) is selected, or if
StabiliTrak is turned off.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See If the
Vehicle Is Stuck 0186 and “Turning the
Systems Off and On” later in this section.
The indicator light for both systems is in the
instrument cluster. This light will:
.Flash when TCS is limiting wheel spin
.Flash when StabiliTrak/ESC is activated
.Flash when ABS is active
.Turn on and stay on when either system
is not working
If either system fails to turn on or to
activate, a message displays in the Driver
Information Center (DIC), and
=comes on
and stays on to indicate that the system is
inactive and is not assisting the driver in
maintaining control. The vehicle is safe to
drive, but driving should be adjusted
accordingly.
If
=comes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
