brake OLDSMOBILE SILHOUETTE 1997 Workshop Manual

What to Add
When
you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 1 1 @ (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.
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
-=-1 crash. Always use the proper brake fluid.
I 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.

Brake Wear
Your Oldsmobile has front disc brakes and rear
drum 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 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: 1
Continuing to drive with worn-out brake pads
could result in costly brake repair.
1
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 br.
c~ k es.
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.
Your rear drum brakes don’t have wear indicators,
but if
you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected.
Also, the rear brake drums
should be removed and inspected each time the tires
are removed for rotation or changing. When you
have the front brakes replaced, have the rear brakes
inspected, too.
Brake linings should always be replaced
as complete
axle sets.

Brake Pedal Travel
See your retailer 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.
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.
Vehicles we design and test have top-quality
GM brake
parts in them, as your Oldsmobile does
when it is new.
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
genuine
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 Oldsmobile 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 retailer to learn how to prepare your
vehicle for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the
same way as the one it replaces.
11 yo^- -1eed 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
Oldsmobile 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.
Used Replacement Wheels
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.

Starter Switch Check
A CAUTION:
When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
I. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake (see “Parking
Brake”
in the Index if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately
if it starts.
3. Try to start the engine in each gear. The starter
should work only
in PARK (P) or NEUTRAL (N). 1.f
the starter works in any other position, your vehicle
needs service.
Irake-Transaxle Shift Interlock (BTSI) Check
When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1.
2.
3.
Before you start, be sure you have enough room
around the vehicle. It should be parked on a
level surface.
Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately if
the vehicle begins to move.
With the engine off, turn the
key to the RUN
position, but don’t start
the engine. Without
applying
the regular brake, try to move the shift
lever out of PARK
(P) with normal effort. If the shift
lever moves out of
PARK (P), your vehicle’s BTST
needs service.

Steering Column Park Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to
LOCK in each shift lever position.
The key should turn to LOCK only when the shift
lever is in PARK
(P).
0 The key should come out only in LOCK.
Parking Brake and Automatic Transaxle PARK (P)
Mechanism Check
When you are doing this check, your vehicle
could begin to move. You
or others could be
injured and property could be damaged. Make
sure there is room in front
of your vehicle in case
it begins
to roll. Be ready to apply the regular
’ brake at once should the vehicle begin to move. Park on
a fairly
steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set
the parking brake.
To check the parking brake’s holding ability: With
the engine running
and transaxle in NEUTRAL (N),
slowly remove foot pressure from the regular brake
pedal.
Do this until the vehicle is held by the parking
brake only.
0 To check the PARK (P) mechanism’s holding ability:
With the engine running, shift
to PARK (P). Then
release all brakes.
Underbody Flushing Service
At least every spring, use plain water
to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.

Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and
for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses
for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition.
Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment.
You may need to have
your brakes inspected more often
if your driving habits
or conditions result in frequent braking.
