brakes OLDSMOBILE SILHOUETTE 1997 Owner's Manual

Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets
you check your
electrical connection at the same time.
During your trip, check occasionally to
be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help
you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to
go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to
the left, just move that hand
to
the left. To move the trailer to the right, move your
hand to
the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well
in advance.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a different turn signal flasher.
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if
the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when
they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear befure you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000 lbs.
(454 kg), you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (D)
(or, as
you need to, a lower gear). This will minimize
heat build-up and extend the life of your transaxle.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a
hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK
(P) yet.
Have someone place chocks under
the trailer wheels.
When
the wheel chocks are in place, release the
regular brakes
until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift
to PARK (P).
Release the regular brakes.

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule
for more
on this. Things that are especially important
in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belts, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.

NOTICE:
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.

Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
6-26
ProCarManuals.com

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.
I A CAUTION: I
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.

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.

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.
