Buick LaCrosse: Brake Fluid
The brake master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 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.
When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light.
What to Add
Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants.
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.
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.
