Brake Fluid - Buick Enclave Owner's Manual

10-24 Vehicle Care

Brake Fluid

The brake master cylinder reservoir
is filled with DOT 3 brake fluid as
indicated on the reservoir cap.
See Engine Compartment Overview
on page 10 6 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.
WARNING
If 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.
I n f o r ma t i o n P r o v i d e d b y :
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5 22.
What to Add
Use only new DOT 3 brake
fluid from a sealed container.
See Recommended Fluids and
Lubricants on page 11 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.
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.
