What to Add
When you do need brake fluid, use only DOT
-
3 brake
fluid. Refer to “Recommended Fluids and Lubricants”
in the Index. Use new brake fluid from a sealed
container only.
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.
CAUTION:
With the wrong kind of fluid in your brake
system, your 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:
D 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 your brake system can damage brake
system parts so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
D 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 “Appearance Care” in the Index.
Brake Wear
If you have four
-
wheel drive, your vehicle has
four
-
wheel disc brakes. If not, your vehicle has front
disc brakes and rear drum brakes.
Disc brake pads have built
-
in wear indicators that make a
high
-
pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
