continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over safely,
and park the vehicle right away.
If there is no sign of steam, idle the engine
for three minutes while parked. If the
warning is still displayed, turn off the
engine until it cools down.
Washer Fluid
What to Use
When the vehicle needs windshield washer
fluid, be sure to read the manufacturer
instructions before use. If the vehicle will be
operating in an area where the temperature
may fall below freezing, use a fluid that has
sufficient protection against freezing.
Adding Washer Fluid
1. Open the hood. SeeHood017.
2. Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip.
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
.When using concentrated washer fluid,
follow the manufacturer instructions
for adding water.
.Fill the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid expansion if
freezing occurs, which could damage
the tank if it is completely full.
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched warning
sound when the brake linings are worn and
new linings are needed. The sound can come
and go or can be heard all the time when
the vehicle is moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning sound means
that soon the brakes will not work well.
That could lead to a crash. When the
brake wear warning sound is heard, have
the vehicle serviced.
Caution
Continuing to drive with worn-out brake
linings could result in costly brake
repairs.
Properly torqued wheel nuts are necessary
to help prevent brake pulsation. When tires
are rotated, inspect brake linings for wear
and evenly tighten wheel nuts in the proper
sequence to torque specifications. See
Capacities and Specifications 0325.

17272984) - 2024 - CRC - 2/20/23
Vehicle Care 263
Brake linings should be replaced as complete
axle sets.
Brake Squeal and Brake Dust
Some driving conditions or climates can
cause a brake squeal when the brakes are
first applied, clearing up following several
applies. This does not mean something is
wrong with the brakes.
Vehicles equipped with high performance
brake systems provide superior fade
resistance but will produce increased brake
squeal and brake dust on the wheels and
calipers as compared to standard brake
linings. This is normal.
To help reduce squeal, the 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 for brakes
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 (Z06/Z07/E-Ray with
J57 Carbon Ceramic Rotors)
Vehicles with the J57 brake option have
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

Vehicle Care 265
How to Reset the Brake Pad Life System
The system will automatically detect when
significantly worn brake pads are replaced.
When the ignition is turned on after new
pads and wear sensors are installed, a
message will display. Follow the prompts to
reset the system.
The brake pad life system can also be
manually reset:1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 099.
2. Select the Brake Pad Life menu.
3. Select front or rear pads as appropriate.
4. Select YES on the confirmation message. Repeat for the pads on the other axle if
they were also replaced.
How to Disable the Brake Pad Life
System
The brake pad life system can be turned off.
This may be necessary if aftermarket brake
pads without wear sensors are installed.
When the system is turned off, the front
and rear brake pad life percentages will not
display. However, the built-in wear
indicators that make a high-pitched warning sound when the brake pads are worn can
still determine when the pads should be
replaced. See
Brakes0262.
To turn off the brake pad life system: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 099.
2. Select the Brake Pad Life menu.
3. Select DISABLE.
To turn the brake pad life system back on,
follow the above steps but select ENABLE in
Step 2.
Electronic Brake Pad Sensor System
(Z06/Z07/E-Ray with J57 Carbon Ceramic
Brake Rotors)
The brake pads have electronic brake pad
wear sensors, when the brake pads need to
be replaced, a message displays in the
Driver Information Center (DIC) which says
“Service Brakes Worn”.
When the message displays, install new
brake pads and brake pad wear sensors on
the vehicle.
When the ignition is turned on after new
brake pads and brake pad wear sensors are
installed, the message should no longer
display. The brake pad sensor system can only be
reset by replacing the brake pads and brake
pad wear sensors.
Brake Fluid
The brake master cylinder reservoir is filled
with GM approved DOT 4 brake fluid as
indicated on the reservoir cap. See
Underhood Compartment Overview
0235 for
the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum marks
on the brake fluid reservoir.
There are only two reasons why the brake
fluid level in the reservoir may go down:
.Normal brake lining wear. When new
linings are installed, the fluid level goes
back up.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
266 Vehicle Care
.A fluid leak in the brake hydraulic system.
Have the brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid reservoir cap
and the area around the cap before
removing it.
Do not top off the brake fluid. Adding fluid
does not correct a leak. If fluid is added
when the linings are worn, there will be too
much fluid when new brake linings are
installed. Add or remove fluid, as necessary,
only when work is done on the brake
hydraulic system.
Caution
If too much brake fluid is added, the
brake fluid can spill and cause vehicle
damage, including damage to electrical
components and surfaces. Add brake fluid
only when work is done on the brake
hydraulic system.
When the brake fluid falls to a low level,
the brake warning light comes on. See Brake
System Warning Light 092. Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Replace brake fluid at the specified intervals
to prevent increased stopping distance. See
Maintenance Schedule
0316.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0320.
{Warning
The wrong or contaminated brake fluid
could result in damage to the brake
system. This could result in the loss of
braking leading to a possible injury.
Always use the proper GM approved
brake fluid.
Caution
If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Immediately wash off any
painted surface.
