Driving and Operating 161
Check the oil level often during track events
and competitive driving. See“Checking the
Engine Oil" in Engine Oil (5.5L LT6 Engine)
0 246 or
Engine Oil (6.2L LT2 Engine) 0249.
Engine Cooling
If reduced performance is experienced during
track events or competitive driving, turning
off the A/C will help to improve engine
performance.
Maintain a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable water to
optimize engine performance.
For vehicles with the optional Grille Screen
Guards (VWE), remove them for track events
when the ambient temperature reaches
32° C (90° F) or higher. See your dealer for
complete procedure.
If equipped, remove the front license plate
and bracket (if installed) and remove the
front aero covers before track use. See your
dealer for complete procedure.
Fuel
Unleaded gasoline, rated at 93 octane or
higher, is required.
Caution
Some high octane fuels contain additives
and compounds that may damage the
vehicle and void the vehicle warranty. See
Prohibited Fuels 0227.
Dual Clutch Transmission (DCT) Fluid
The transmission fluid and external canister
filter should be changed after every 24 hours
of track use. Change the fluid and external
canister filter as soon as possible if
prompted by the transmission fluid life
monitor that remaining fluid life is low.
With the transmission at factory fluid fill,
there is no additional fluid needed for track
usage. Any transmission level set or change
should be performed at your dealer.
Front Hybrid Drive Unit Fluid (E-Ray)
If equipped, the front hybrid drive unit fluid
should be changed after every 15 hours of
track use. This procedure can be complex,
see your dealer.

17272984) - 2024 - CRC - 2/20/23
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

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
Driving and Operating 163
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 Driver Information Center (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.
Stage 2 : The Driver Information Center
(DIC) displays a “Brakes Overheated Service
Now” message, a chime sounds, and brake
pedal effort and travel is further increased.
This code indicates that the brake fluid
temperature is excessive and is about to
boil. The system limits vehicle speed to
100KPH/62MPH. The driver should
immediately start a cool down lap if on the
track. If this message displays, the vehicle
needs to be serviced. The brake system
needs to cool down, and the brake fluid
must be immediately flushed with DOT4 for
street use, or to a qualified DOT4 race fluid
for track use. Boiled brake fluid is
compromised and must be replaced. Brake Burnishing
Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In
0177.
Caution
Brake pedal fade will occur during any
track burnish procedure and can cause
brake pedal travel and force to increase.
This could extend stopping distance until
the brakes are fully burnished.
New brake pads must be burnished before
racing or other competitive driving.
When this procedure is performed as
instructed, it will not damage the brakes.
The brake pads will smoke and produce an odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
Brake Burnishing Procedure for J55 (Stingray
with Z51) and J56 (Z06 Standard) Brakes
This brake burnish procedure should only be
performed on vehicles with the Z06 with
J56, or Z51 with J55 factory equipped brake
systems.
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. See Instrument Cluster 081. This is
a medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Apply the brakes 25 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 without activating the

17272984) - 2024 - CRC - 2/20/23
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.

Shock Spring Seat Adjustment
The front shocks, on vehicles without
hydraulic front lift and rear shocks, have
threaded spring seats that allow adjustment
of the preload on the coil springs. The
vehicle corner weights can be adjusted for
track use. If the vehicle trim height is
modified, it should be returned to normal
trim height before street use.
The spring seat can be adjusted
approximately 20 mm (0.8 in) up or down
from the nominal position. Each complete
turn of the spring seat will change the
vehicle height approximately 1.5 mm
(0.06 in). When adjusting the seat to the
upper limit, lift the dust boot and ensure
the seat does not thread off the center
support tube (stop adjustment when threads no longer visible). When adjusting the seat
to the lower limit, leave approximately
10 mm (0.4 in) of thread visible for the
lower lock nut to have full thread
engagement.
The following procedure can be complex and
should only be performed by trained
personnel. See your dealer.
To adjust the lower spring seat:
1. Raise the vehicle so the tires are completely off the ground.
