GMC 2010 Tahoe, Owner'S Manual

Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir.
See
Engine Compartment Overview on page 6 ‑ 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.
{
WARNING:
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.
