Checking Brake Fluid
You can check the brake fluid without taking off
the cap.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not
over the MAX mark.
What to Add
When you do need brake fluid, use only DOT-3
brake fluid. Use new brake fluid from a sealed
container only. See Recommended Fluids
and Lubricants on page 447.
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
Look at the brake fluid
reservoir. The fluid level
should be above
MIN. If it is not have the
brake system checked
to see if there is a leak.
CAUTION:
{
With the wrong kind of fluid in the brake
system, the brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake fluid.
Notice:
•
Using the wrong fluid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of fluid.
•
If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can
be damaged. Be careful not to spill brake
fluid on your vehicle. If you do, wash it
off immediately. See Washing Your Vehicle
on page 419.
