Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the
brake fluid level in your master cylinder
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.
Refer to the Maintenance Schedule to
determine when to check your brake
fluid. See
Periodic Maintenance
Inspections
in the Index.
To Check Brake Fluid
You can check the brake fluid without
taking
off the cap. Just look at the
windows on the brake fluid reservoir.
The fluid levels should be above
MIN. If
they aren’t, have your brake system
checked to see
if there is a leak.
After work is done on the brake
hydraulic system, make sure the levels
are above
MIN and below the top of
each window.
What to Add
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco
Supreme
11s (GM Part No.1052535).
Use new brake fluid from a sealed
container only, and always clean the
brake fluid reservoir cap before
removing it.

wrong kind of fluid. 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.
Brake fluid can damage paint, so
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).
I NOTICE:
I
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.
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 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 make a brake stop, your
disc brakes adjust for wear.
If your brake pedal goes down farther
than normal, your rear drum brakes
may need adjustment. Adjust them by
backing up and firmly applying the
brakes a few times.
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 179

Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,
CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 1OW-
30), see the Index under Engine Oil.
2. Chassis Lubrication - Lubricate the
transmission shift linkage, parking
brake cable guides, underbody contact points and linkage. Lubricate the front
suspension and steering linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions
in this
manual. See
Tires, Inspection G.
Rotation in the Index. Check the
tires for uneven wear or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Inspection - Inspect the drive belt
for cracks, fraying, wear and proper
tension. Replace as needed.
5. Cooling System Service‘: - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to
GM Specification
6038-M. Keep coolant at the proper
mixture as specified. See
CooZant in
the
Index. This provides proper
freeze and boil protection, corrosion
inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps. Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
4. Engine Accessory Drive Belt
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
6. Transmission Service - Change
both the fluid and filter every 15,000
miles
(25 000 lun) if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police
If you do not use your vehicle under

14. Differential (Axle) Service-Check
rear/front differential fluid level and
add as needed. Check constant
velocity joints and axle seals for
leaking.
Locking Rear Differential -Drain
fluid at first engine oil change and
refill. Check fluid level and add as
needed at subsequent oil changes. In
dusty areas, or trailer towing
applications, drain fluid at every
15,000 miles (25 000 ltm) and refill.
More frequent lubrication may be
required during heavy-duty or off-
road use. A fluid loss in this system
may indicate
a problem. Have it
inspected and repaired at once.
15. Brake Systems Inspection-When
the engine oil is changed, inspect
the lines and hoses for proper
hookup, binding, leaks, craclts,
chafing, etc. Check the parking
brake adjustment and the fluid level
in the master cylinder. A low brake
fluid level can indicate worn disc
brake pads which may need to be
serviced.
A fluid loss in this system may indicate a problem. See
the
Index under Brake System Warning
Light. When the wheels are
removed for rotation, inspect disc
brake pads for wear and rotors for
surface condition. Also inspect
drum brake linings for wear and
craclts. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc. at the
same time.
You may need to have your brakes
inspected more often
if your driving
habits or conditions result in
frequent braking.
16. Transfer Case Fluid Change -In
heavy or frequent trailer towing
applications, drain fluid and refill
every
30,000 miles (50 000 ltm).

WHAT TO DO
CAUTION: 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 ther\
e 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: With the engine running and transmission in N (Neutral), slowly
remove foot pressure
from the regular brake pedal. Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism's holding ability: Shift to P (Park). Then release all brakes.
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.
Check rear/front differential fluid level and add as needed. Check constant velocity joints and
axle seals for leaking.
Check transfer case fluid level. Check vent hose at transfer case for ltinlts and proper installation.
More frequent lubrication may be required on heavy-duty off-road use.
A fluid loss may indicate a
problem. Have it inspected and repaired
at once.
