Brake Fluid - Chevrolet EXPRESS - 2011 Manual

The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.
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 brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
If too much brake fluid is
added, it can spill on the engine
and/or fuel operated heater parts,
if equipped. If the vehicle has a
diesel engine and a fuel operated
heater, see Fuel Operated
Heater (FOH) in the diesel
engine supplement. The fluid will
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. See Checking
Brake Fluid in this section.
Refer to the Maintenance Schedule
to determine when to check the
brake fluid. See
Check brake fluid by looking at the
brake fluid reservoir. See
.
The fluid level should be above
MIN. If it is not, have the brake
hydraulic system checked to see if
there is a leak.
