162 Driving and Operating
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
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 the system diagnosing 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 and Bleeding
The J55, J56, and J57 brake systems require
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. To avoid
inadvertently setting a leak 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 brake system performance. 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

164 Driving and Operating
Antilock Brake System (ABS). Drive for at
least 1 km (0.6 mi) between applications.
Depending on conditions, some increase
in brake pedal travel and brake pedal
force may be experienced.
3. Cool down: Drive at 100 km/h (60 mph) for approximately 15 km (10 mi) without
using the brakes.
4. Apply the brakes 25 times from 100 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.
Brake Burnishing Procedure for Z06 and
E-Ray with Available J57 Carbon Ceramic
Brakes
This brake burnish procedure should only be
run on Z06 and E-Ray vehicles with J57
factory equipped brake systems.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances regarding motor vehicle
operation. 1. Using the friction bubble in the Cluster
Performance menu, apply the brakes 25
times starting at 100 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 1.6 km
(1.0 mi) between applications. This first
step may be skipped if there are more
than 320 km (200 mi) on the brake pads.
2. Apply the brakes 20 times starting at 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a
hard brake application. Drive for at least
1.6 km (1.0 mi) between applications.
3. Apply the brakes 12 times starting at 100 km/h (60 mph) to 8 km/h (5 mph)
while decelerating at 0.8 g. This is a
hard brake application. Accelerate as
rapidly as possible without activating
traction control between applications.
4. Cool down: Drive at 100 km/h (60 mph) for approximately 15 km (10 mi) without
using the brakes.
As with all high performance brake systems,
some amount of brake squeal is normal. Alternative Closed Course Brake Burnishing
Procedure for J55 (Stingray with Z51), J56
(Z06 Standard), and J57 (Z06 and E-Ray
Carbon Ceramic) Brakes
This brake burnish procedure should be run
on vehicles with the Z51 with J55, Z06 with
J56, or Z06 and E-Ray with J57 factory
equipped brake systems.
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.

wheel is exposed to the heat. Rolling the
car back and forth in a small space is
better than sitting still with hot brakes.
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
vehicle occupants could drown. Do not(Continued)
Warning (Continued)
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Caution
Driving through deep puddles or standing
water can cause water to come in
through the engine air intake and
damage the engine. If deep puddles or
standing water cannot be avoided,
proceed with caution and do not exceed
8 km/h (5 mph). Do not drive through
water that may come close to or cover
the vehicle’s underbody.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
SeeTires 0279.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.When driving downhill in D (Drive), the
vehicle may automatically downshift to
assist with speed control.
.A lower gear may also be selected to
provide further speed control.

178 Driving and Operating
Ignition Positions
The vehicle has an electronic keyless ignition
with pushbutton start.
The remote key must be in the vehicle for
the system to operate. If the pushbutton
start is not working, the vehicle may be
near a strong radio antenna signal causing
interference to the Keyless Access system.
SeeRemote Key Operation 07.
To shift out of P (Park), the vehicle must be
turned on and the brake pedal must be
applied. 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

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 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 0192. Press ENGINE
START/STOP to turn the vehicle off.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
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.
Accessory (Amber Indicator Light) : This
mode allows the use of some electrical
accessories when the engine is off.

17272984) - 2024 - CRC - 2/20/23
Driving and Operating 191
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:
.Accelerator pedal is fully released
.Vehicle speed is above 10 km/h (6 mph)
.Vehicle is in R (Reverse)
.Paddles are released separately
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.
Rapid Exit : This is intended for use at a
closed course race track and not on public
roads. Engine power is reapplied to the
wheels quickly to support spirited driving.
The rate of launch is dependent on how
much the accelerator pedal is pressed when
the paddles are released. The further the
accelerator pedal is pressed, the greater the
rate of launch. Tire spin may occur if the
Traction Control System (TCS) is turned off
while performing a Rapid Exit. Rapid Exit
launch occurs when all of the following
conditions are met:
.Vehicle speed is below 10 km/h (6 mph)
.Vehicle is in D (Drive) or
M (Manual Mode)
.Both paddles 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).
Manual Launch : While the vehicle is in
Double Paddle Declutch, Manual Launch can
be activated to gain more precise control
over the engine speed to prepare for a
Standard or Rapid Exit. To activate this
feature, first enter Double Paddle Declutch,
then release and repull either the + paddle
or −paddle while keeping the opposite
paddle held. The Performance Transmission
Active Light will illuminate in the gauge
cluster to indicate that Manual Launch has
been activated. See Performance
Transmission Active 093. When Manual
Launch is active, the engine will respond
differently when the accelerator pedal is
pressed compared to normal Double Paddle
Declutch. The accelerator pedal must be
pressed further to increase the engine rpm
and a lower engine rpm limit will be
applied. This feature also provides faster engine response during a Rapid Exit if any
of the Performance Traction Management
(PTM) modes or Electronic Stability Control
(ESC) Off has been selected. To exit Manual
Launch, release both the + paddle and
−
paddle. The vehicle will also exit Double
Paddle Declutch and the engine will
reconnect to the wheels. A Standard Exit or
Rapid Exit will be performed based on the
same conditions listed previously.
{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.
Drive Systems
All-Wheel Drive
If equipped with E-Ray, advanced electric
All-Wheel Drive (eAWD) delivers power to all
four wheels and adjusts automatically to the
driving conditions. The eAWD system
continuously varies the drive power to the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
192 Driving and Operating
front and rear wheels to maximize driving
efficiency and improve driving dynamics.
Your vehicle has exceptional driving
capability, but care must always be taken to
adjust driving style to the traffic and road
conditions.
The vehicle eAWD settings may be
customized for the driver mode selected. See
Driver Mode Control0196 for more
information.
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 093.
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.
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 EPB
cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
Driving and Operating 193
The system has a red parking brake status
light and an amber service parking brake
warning light. SeeElectric Parking Brake
Light 092 and
Service Electric Parking Brake Light 092.
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 accessory mode.
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
