Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
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 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.
CAU-ION:
-
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.
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Add
When you do need brake fluid, use only DOT-3
brake fluid
-- such as Delco Supreme ll@ (GM Part
No. 12377967). 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.
’ A CAUTION:
I -
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:

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.

Your Cadillac 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).
c
The brake wear warning sound means that soon
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.
Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts
are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in
the proper sequence to
GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection’, in the Maintenance
Schedule booklet under Part C “Periodic Maintenance
Inspections”.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Downloaded from www.Manualslib.com manuals search engine 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 have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved
GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example, if someone puts in brake 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.
Battery
Every new Cadillac has a Delco Freedom@ battery. You
never have to add water to one
of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take off the black, negative
(-) cable from
the battery.
This will help keep your battery from
running down.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips
on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature” in the Index.

Downloaded from www.Manualslib.com manuals search engine If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment
parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your
Cadillac model.
---
~ Using the wrong replacement wheels, wneel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or
tire chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how far it’s been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new
GM original equipment wheel.
