Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid.
won't work at all. So, it isn't a good idea to "top off'
your brake fluid. Adding brake fluid won't correct a
leak. If you add fluid when your linings are worn, then
you'll 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.
A
CAUTION:
If you
have too much brake fluid,
it
can spill on
the engine. The fluid will burn if the engine is hat
,..ough. You
or
others could be burned,
and
you1
vehicle could be damaged. Add brake fluid only
when work i s done on the brake hydraulic
system.
There are only two reasons why the brake fluid level in
your master cylinder 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 won't work well, or
When your brake fluid falls to a low level, your brake
warning light will come on. See "Brake System Warning
Light" in the Index.
When your brake fluid falls to a low level, your brake
warning light will come on and a chime will sound.
