c How to Add Fluid:
Refer to the Maintenance Schedule to
determine
what kind oftransmission
fluiil to use. See the Index under Fluids.
G Lubricants.
If the fluid level is low, add only enough
of the proper fluid to bring. the level up
to the COLD area.for a cold-check or
the-HQT
area for a-.hot ‘check. It
doesn’t take much fluid, generally legs
than a pint. Don’t overfill. We
recommend
you use only fluid IabeIed
DEXRON@-JIE, because fluids with that
label are made especially
for your
automatic transmission.. Damage caused
by fluid other than DEXXO-Nq-IIE is not
covtir,ed by your-new vehicle warranty.
After adding fluid, recheck the fluid
level as described under How to Check.
When the correct fluid level is obtained,
push

To check the fluid, look at the area
between the
ECM and the battery.

Brake Master Cylinder
Your brake master cylinder is filled with
DOT-3 brake fluid.
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 Iealring
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 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.

systems are disabled when your brake
flu.id falls to
it low level. See thedndex
under
Brake System Warning Light;
To Add Brake Fluid:
Lift the cap and pour in fluid to the
MAX mark on the master cylinder. Do
not oveffiI1.
&%at to Add:
When you do need brake fluid, use-
)nly
DOT-3 brake fluid-such as
lelcrr Supreme 1P (GM Part No.
.052535). Use new brake fluid from a
'eded. container only.
NOTlCE
Replacing Brake System Parts
The braking system on a modern
vehicle is
complex. Its many parts have
to be
of top quality -and work well
together if the vehicle is to haye really
good braking. Vehicles we design and
test have top-quality GM brake-parts in
the&, as
your Corvette does when it is
new. When you replace parts of your
braking 'system-for example, when
your brakelinings wear down and you
have to have new ones put in-be sure
you get new genuine GM replacement
parts. If.you don't, your brakes may no
longer work properly. For example, if
someone.puts
in b.r&e linings that are
wrong for your vehicle, .the balance
between your
front and rear brakes can
change, for the worse. The braking
performance
you've come to expect can
change in many other ways if.-someone
puts
in the wrong replacement brake
parts.
