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 Schedple to
determine when to check
yoqr drake
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 brakl
fluid reservoir cap before removing it.
NOTICE:
Don’t let someone put in the
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 Geo 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).

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.
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 Geo 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 Geo has a Delco Freedoms
battery.
You never have to add water to
one
of these. When it’s time for a new
battery, we recommend a Delco
Freedoma battery. Get one that has the
catalog 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

Maintenance Schedule
Section C: Periodic Maintenance Inspections (cont.)
INSPECTION
OR SERVICE
Rear Axle (All) and
Front Axle (Four-
Wheel Drive) Service
Brake System
Inspection
Clutch System Service
WHAT SHOULD BE DONE
Check the gear lubricant level and add if needed. See “Rear Axle” and “Four-Wheel Drive” in
the Index. A fluid loss may indicate a problem. Check the system(s), and repair the system(s) if
needed. Refer to “Scheduled Maintenance Services,” earlier in
this part, to determine when to
change the lubricant.
Inspect the complete system. Inspect brake lines and hoses for proper hookup, 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.
NOTE: A low brake fluid level can indicate worn disc brake pads which may need to be serv-
iced. Also,
if the brake system warning light stays on or comes on, something may be wrong
with either the regular or rear wheel anti-lock brake system, or both systems. See “Brake System
Warning Light” in the Index.
Check clutch pedal free travel and adjust
as necessary. See “Clutch Adjustment” in the Index. ..
