Brakes
Brake Fluid
The brake master
cylinder reservoir is lled
with DOT-3 brake uid.
SeeEngine Compartment
Overview on page 5-14for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down:
The brake uid level goes down because of normal
brake lining wear. When new linings are installed,
the uid level goes back up.
A uid leak in the brake hydraulic system can also
cause a low uid level. Have the brake hydraulic
system xed, since a leak means that sooner
or later the brakes will not work well.Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings are worn,
there will be too much uid when new brake linings are
installed. Add or remove brake uid, as necessary, only
when work is done on the brake hydraulic system.
{CAUTION:
If too much brake uid is added, it can spill on
the engine and burn, if the engine is hot enough.
You or others could be burned, and the vehicle
could be damaged. Add brake uid 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 uid. SeeScheduled Maintenance
on page 6-4.
5-44

Checking Brake Fluid
Check brake uid by looking at the brake uid reservoir.
SeeEngine Compartment Overview on page 5-14.
The uid 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 uid from a sealed
container. SeeRecommended Fluids and Lubricants
on page 6-12.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This helps keep
dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake uid.
Notice:
Using the wrong uid 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 uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-95.

Brake Wear (Except ZR1)
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 rmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
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 rst 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 Only)
The ZR1 model does 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.
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.Front

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.
SeeDIC Warnings and Messages on page 3-54.Some driving conditions or climates can cause a brake
squeal when the brakes are rst 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 conrm 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. SeeService
Publications Ordering Information on page 7-15.
5-47

Brake Rotor Protector
{CAUTION:
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.
5-48

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/retailer.
Brake Pedal Travel
See your dealer/retailer 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.
