Brakes
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.
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
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.
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:
a
a
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 Pedal Travel Replacing Brake System Parts
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 make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then -- very carefully -- make
a few moderate brake stops about every
1,000 miles
(1 600 h), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
pumping the brake pedal repeatedly while the engine is
running with the shift lever in
PARK (P).
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 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.

Used Replacement Wheels
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.
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.

Do this until the vehicle is held by the parking
brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK

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.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and servlces which should be
performed at least twice a year (for instance, each spring
and fall). You should let your
GM retailer’s service
department or other
qualified service center do these jobs.
Make sure
any necessary repairs are completed at once.
Proper procedures to perform these services may be
found
in a GM service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near
the exhaust system.
Look for broken, damaged, missing or
out-of-position parts
as well as open seams, holes, loose connections or other conditions
whch could cause a heat
build-up in the floor pan or could let exhaust fumes into
the vehicle.
See “Engine Exhaust” in the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace
as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damaged 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. The
parking brake is self-adjusting and no manual adjustment is required. You may need
to have your
brakes inspected more often
if your driving habits or
conditions result
in frequent braking.
