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.
The ZR1 and ZO6 also have an
electronic brake pad wear sensor
system. When pads are worn, the
CHANGE BRAKE PADS message
displays in the Driver Information
Center. See
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 and ZO6 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
