Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, be sure to read the
manufacturer's 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
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. SeeEngine
Compartment Overview on
page 10‑8 for reservoir location. Notice
.When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water.
.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.
Also, water does not clean as
well as washer fluid.
.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.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
Brakes
Brake Wear (Except ZR1, Z06,
and Grand Sport)
This vehicle has disc brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time 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.

Black plate (35,1)Chevrolet Corvette Owner Manual - 2012
Vehicle Care 10-35
Notice:Continuing to drive with
worn-out brake pads could result
in costly brake repair.
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 Wear (ZR1, Z06, and
Grand Sport Only)
The ZR1, Z06, and Grand Sport
models do not have built-in brake
pad wear indicators and periodic
visual inspection of the brake pads
is required to determine when to
replace the brake pads. Notice:
Continuing to drive with
worn-out brake pads could result
in costly brake repair.
.Make sure that the brakes have
been given sufficient time to cool
and then set the park brake.
Rear
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 2 mm of pad
thickness. New pads are 10 mm
thick.
.In addition, brake pad inspection
is required any time the tires are
removed.

Black plate (36,1)Chevrolet Corvette Owner Manual - 2012
10-36 Vehicle Care
The ZR1, Z06, and Grand Sport
models also have 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, and Z06 and
Grand Sport models may 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 13‑18. 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.

Black plate (37,1)Chevrolet Corvette Owner Manual - 2012
Vehicle Care 10-37
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.
Replacing Brake System Parts
The braking system on a vehicle
is complex. Its many parts have to
be of top quality and work well
together if the vehicle is to have
really good braking. The vehicle
was designed and tested with
top-quality brake parts. When
parts of the braking system are
replaced—for example, when the
brake linings wear down and new
ones are installed —be sure to get
new approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
if someone puts in brake linings
that are wrong for the vehicle, the
balance between the front and rear
brakes can change —for the worse.
The braking performance expected
can change in many other ways if
the wrong replacement brake parts
are installed.

10-38 Vehicle Care
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid.
SeeEngine Compartment Overview
on page 10‑8 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
.The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.
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 brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{WARNING
If too much brake fluid is added,
it can spill on the engine and
burn, if the engine is hot enough. (Continued)
WARNING (Continued)
You or others could be burned,
and the vehicle could be
damaged. Add brake fluid only
when work is done on the brake
hydraulic system. See “Checking
Brake Fluid” in this section.
Refer to the Maintenance Schedule
to determine when to check the
brake fluid. See Maintenance
Schedule on page 11‑3.

Black plate (39,1)Chevrolet Corvette Owner Manual - 2012
Vehicle Care 10-39
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. SeeEngine
Compartment Overview on
page 10‑8.
The fluid level should be above the
MIN mark on the reservoir. If it is
not, have the brake hydraulic
system checked to see if there is
a leak.
After work is done on the brake
hydraulic system, make sure the
level is between the MIN and MAX
marks. What to Add
Use only new DOT 3 brake
fluid from a sealed container.
See
Recommended Fluids and
Lubricants on page 11‑12.
Always clean the brake fluid
reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{WARNING
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well.
This could cause a crash.
Always use the proper brake fluid. Notice
.Using the wrong fluid
can badly damage brake
hydraulic system parts.
For example, just a few
drops of mineral-based oil,
such as engine oil, in the
brake hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.

Tire Designations
Tire Size
The following is an example
of a typical passenger vehicle
tire size.
(A) Passenger (P‐Metric) Tire:
The United States version
of a metric tire sizing system.
The letter P as the first
character in the tire size
means a passenger vehicle
tire engineered to standards
set by the U.S. Tire and Rim
Association.
(B) Tire Width
:The three‐digit
number indicates the tire
section width in millimeters
from sidewall to sidewall. (C) Aspect Ratio
:A two‐digit
number that indicates the tire
height‐to‐width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:
A letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or
bias ply construction; and the
letter B means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:
These characters represent
the load index and speed rating
of the tire. The load index
represents the load carrying capacity a tire is certified to
carry. The speed rating is the
maximum speed a tire is
certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
