What To Add; Brake Wear - Chevrolet 2008 Cobalt Owner's Manual

What to Add

When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container
only. See Recommended Fluids and Lubricants on
page 6-12.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This helps keep
dirt from entering the reservoir.
CAUTION:
{
With the wrong kind of fluid in the brake or
clutch hydraulic system, the brakes or clutch
might not work well. This could cause a crash.
Always use the proper brake fluid.
5-32
Notice:
•
Using the wrong fluid can badly damage brake
or clutch hydraulic system parts. For example,
just a few drops of mineral-based oil, such
as engine oil, in the brake or clutch hydraulic
system can damage brake or clutch hydraulic
system parts so badly that they will have
to be replaced. Do not let someone put in the
wrong kind of fluid.
•
If you spill brake fluid on your vehicle's painted
surfaces, the paint finish can be damaged. Be
careful not to spill brake fluid on your vehicle.
If you do, wash it off immediately. See Washing
Your Vehicle on page 5-99.

Brake Wear

Your vehicle has front disc brakes and could have rear
drum brakes or rear 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 your vehicle
is moving, except when you are pushing on the
brake pedal firmly.
