9-8 Driving and Operating
If the vehicle is used for racing or
other competitive driving, the rear
axle fluid temperatures may be
higher than would occur in normal
driving. We recommend that the
rear axle fluid be drained and
refilled with new fluid after every
24 hours of racing or competitive
driving. SeeRecommended Fluids
and Lubricants on page 11‑6 for
what fluid to use.
ZR1 Brake Burnish Procedure
Notice: These procedures are
specific to the ZR1 with ceramic
brake rotors. These procedures
should not be run on other
Corvette models as damage
may result.
Notice: The new vehicle break‐in
period should be completed
before performing the brake
burnish procedure or damage
may occur to the powertrain/
engine. See New Vehicle Break-In
on page 9‑18. When performed as instructed,
these procedures will not damage
the brakes. During the burnishing
procedure, the brake pads will
smoke and produce an odor.
The braking force and pedal travel
may increase. After the procedure
is complete, the brake pads may
appear white at the rotor contact.
Street High Performance Brake
Burnishing Procedure
Run this procedure in a safe
manner and in compliance with all
local and state ordinances/laws
regarding motor vehicle operation.
Run this procedure only on dry
pavement.
1. From a stop, accelerate as
rapidly as possible without
activating traction control to
a speed of 97 kph (60 mph).
2. Use enough pedal force to completely stop the vehicle in
4 to 5 seconds. If ABS activates,
braking is too hard. 3. Repeat steps 1 and 2, 5 times.
This should take about
10 minutes.
4. After completing the 50 stops, cool the brakes by driving
for 8 km (5 miles) at 97 kph
(60 mph).
As with all high performance brake
systems, some amount of brake
squeal is normal.
Racing/Track Brake Burnish
Procedure
To prepare the ZR1 brake system
for track events and racing, the
Street High Performance Brake
Burnish as described previously
should be completed.
In addition to completing the Street
High Performance Brake Burnishing
Procedure, the following additional
procedure needs to be completed to
make the ZR1 brake system ready
for track events and racing.
This procedure should only be
run on a track and only on dry
pavement.

Front
.Brake pads can be visually
inspected through the wheel by
inspecting the outer brake pads
at each wheel.
.Brake pads should be replaced
when worn to two mm of pad
thickness. New pads are 10 mm
thick.
.In addition, brake pad inspection
is required any time the tires are
removed.
The ZR1 also has an electronic
brake pad wear sensor system.
When pads are worn, the CHANGE
BRAKE PADS message displays
in the Driver Information Center.
SeeBrake System Messages on
page 5‑36.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Brake linings should always be
replaced as complete axle sets. Brake Rotor Wear
ZR1 models have ceramic brake
rotors. Rotors should be visually
inspected whenever the brake pads
are replaced. 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. Rotor
inspection and weighing methods
can be found in the service manual.
See
Service Publications Ordering
Information on page 13‑15.

10-40 Vehicle Care
Brake Rotor Protector
{WARNING
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
Notice: Rotors may be chipped
if hard contact is made with the
wheel during wheel installation
or removal. Always use the rotor
protectors. Be sure to carefully
follow wheel removal and
installation instructions.
A rotor protector should always be
installed before any wheel removal.
The protector can be installed by
feeding it through the wheel spokes
and slipping it over the outer edge
of the rotor. Leave the protector in
place, over the rotor edge, until
the wheel is re‐installed. Rotor
protectors are available through
your dealer.
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 might
be required.
Brake Adjustment
Every brake stop, the disc brakes
automatically adjust for wear.

Vehicle Care 10-79
{WARNING
Rust or dirt on a wheel, or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
you change a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
you can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if you need to, to get all
the rust or dirt off.Tightening Wheel Lug Nuts
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
If you do, the wheel nuts might
come loose and the wheel could
fall off, causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts. Notice:
Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence as shown.
