VEHICLE CARE
This is a medium brake application.

between applying the brakes.

discs is needed, repeat this
procedure with 0.7g applications.
As with all high performance brake
systems, some amount of brake squeal
is normal.
Brake Pad Life System (If
Equipped)
When to Change Brake Pads
If equipped, this system estimates the
remaining life of the front and rear
brake pads. Brake Pad Life is displayed
in the Driver Information Center
(DIC), along with a percentage for
each axle. The system must be reset
every time the brake pads are
changed.
When the system has determined that
the brake pads need to be replaced, a
message displays, which may include
mileage remaining.
Brake pads should always be replaced
as complete axle sets.
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)
or
Driver Information Center (DIC)
(Uplevel)
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
To turn off the brake pad life system:
1. Display Brake Pad Life on the DIC.
See
Driver Information Center (DIC)
or
Driver Information Center (DIC)
(Uplevel)
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.
