Brake Fluid
Your brake master cylinder
reservoir is filled with
DOT-3 brake fluid. See
Engine Compartment
Overview on page 5-12 for
the location of the reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluid
level goes back up. The other reason is that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes will not work well, or will not work
at all.
So, it is not a good idea to top off your brake fluid. Adding
brake fluid will not correct a leak. If you add fluid when
your linings are worn, then you will have too much fluid
when you get new brake linings. You should add or
remove brake fluid, as necessary, only when work is
done on the brake hydraulic system.
{ CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is
hot enough. You or others could be burned, and
your 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 your brake fluid. See Scheduled Maintenance
on page 6-4.
