your brake system fixed, since a leak means that
sooner or later your brakes won’t work well, or 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.
I ’
A CAUTION:
When your brake fluid falls to a low level, your brake
warning light will come on. A chime will sound if you
try
to drive with this warning light on. See “Brake
System Warning Light” in the Index.
What to Add
When you do need brake fluid, use only
DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing
it.
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. 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:
a
a 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.
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
Your Aurora has four-wheel disc 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).
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
