CHEVROLET 2009 Silverado - Manual (Page 56)

Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir.
See Engine Compartment Overview on page 5-4.
With the engine not running for at least one minute, the
maximum fluid level (A) is at the top of the reservoir
body. With the engine running, the fluid level should be
in the proper operating range (B) between the MIN
and MAX marks. 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, with the engine running, is in the proper
operating range (B) between the MIN and MAX marks.
What to Add
Use only new DOT 3 brake fluid from a sealed container.
See “Recommended Fluids and Lubricants” in the
owner manual.
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 hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.
Notice:
• Using the wrong fluid 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 fluid.
• If brake fluid is spilled on the vehicle’s painted
surfaces, the paint finish can be damaged.
Be careful not to spill brake fluid on the vehicle.
If you do, wash it off immediately. See “Washing
Your Vehicle” in the owner manual.
