Brake Master Cylnder
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 pu\
t 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 y\
our brake fluid. See “Periodic Maintenance Inspections” in the Index.

Downloaded from www.Manualslib.com manuals search engine To Check Brake Fluid
I 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
‘“IN.’’ 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
II@ (GM Part No.1052535). Use new brake fluid from a
sealed container only, and always clean the brake fluid reservo\
ir 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.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle 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 w\
hen 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 rabbing noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each time the\
tires itre
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, o\
r 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.

Downloaded from www.Manualslib.com manuals search engine 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 topquality GM brake parts in
them, as your vehicle 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 vehicle 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 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 will help keep your battery
from running down.
Contact your dealer to learn how to prepare your vehicle for longer storage
periods.

Downloaded from www.Manualslib.com manuals search engine You must weigh any accessories, trailer hitches or other equipment you a\
dd
to your vehicle. Then, subtract this extra weight from the CWR\
. This extra weight may shorten the center of gravity zone for your vehicle. Your dealer
can help you with this.
If your slide-in camper and its load weigh less than the CWR, the center of
gravity zone
for your vehicle may be larger.
Your dealer can help you make a good vehicle-camper match. He’ll also
help you determine your CWR.
After you’ve loaded your vehicle and camper, drive to a wei\
gh station and weigh on the front and rear wheels separately. This will tell you the loads on
your axles. The loads on the front and rear axles shouldn’t be more than
either
of the GAWRs. The total of the axle loads should not be more than
the GVWR.
Open your driver’s door and look at the door lock pillar for the
CertificationD‘ire label to find out your GAWR and GVWR.
11 you ve gone over ; Jr weight ratings, move or take out some things until
all the weights fall below the ratings. Of course, you should always tie down
any loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check the manu\
facturer’s instructions.
If you want more information on curb weights, cargo weights, cargo weight
rating and the correct center of gravity zone for your vehicle, your dealer
can help you. Just ask for a copy of “Consumer Information, Truck
-
Camper Loading.”
Trailer Recommendations
You must subtract your hitch loads from the CWR for your vehicle. Weigh
your vehicle with your trailer attached,
so that you won’t go over the
GVWR or the GAWR.
You’ll get the best performance if you spread out the weight of your load
the right way, and if you choose the correct hitch and trailer brakes.
For more information, see “Trailer Towing’’ in the Index.
Pickup Conversion To Chassis Cab
General Motors is aware that some vehicle owners may consider having the
pickup
box removed and a commercial or recreational body installed.
However, we recommend that conversions of this type not be done to this
pickup. Owners should be aware that, as manufactured, there are differences
between a chassis cab and a pickup with the box removed which\
may affect vehicle safety.
For further information, contact the GM Zone Office for your
area. (See the “Warranty and Owner Assistance” booklet fo\
r Zone Office.)

Downloaded from www.Manualslib.com manuals search engine If you need 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
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain\
clearance to the body and chassis.
