How to Turn Off 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 Brakes 3236.
To turn off the brake pad life system:
1. Place the vehicle in P (Park).
2. From the infotainment home screen, select
Vehicle Status >Maintenance >Brake Pad
Life. See Vehicle Status 3103.
3. Touch TURN OFF.
To turn the brake pad life system back on,
fo
llow the previously listed steps and touch
TURN ON in the last step.
Brake Fluid
The brake master cylinder reservoir is filled
wi
th GM approved DOT 4brake fluid as
indicated on the reservoir cap. See Engine
Compartment Overview 3226 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.
•
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.
{ Warning
I
f too much brake fluid 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
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 395.
