1998 CADILLAC DEVILLE brake

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle 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).
r
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.
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.

The braking system on a modem 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 an ACDelco Freedom@ battery.
You never have to add water to one
of these. When it’s
time for a new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.
--‘-icle ~~~ Storage
lr’ you’re not going to drive your vehicle for 25 days
or more, remove 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 Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks
air, replace it (except some aluminum
wheels, which can sometimes be’repaired). See your
dealer
if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
Each
new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
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, wheel
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.
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.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse?
An electrical overload will
cause the lamps to go on and
off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse
is a registered trademark of Little Fuse ,
Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools.
If the overload,
is caused by some electrical problem, be sure to have
it fmed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the cifcuit breaker opens and closes, protecting the circuit until the problem
is fixed or goes away.
MaxiFusesLRelay Center
The MaxiFuses and relays are located next to the engine
compartment fuse b1oc.k on the driver’s side
of the
engine.
To access the compartment fuse block, remove
the shroud cover.
If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the identical size
and rating.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one that has the same amperage. Pick some feature
of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
