1996 CHEVROLET EXPRESS brakes

Downloaded from www.Manualslib.com manuals search engine 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.
Free movement
or Drake calipers and properly torqued
wheel nuts
are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, 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 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.

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 top-quality
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 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.

While parked, and with the parking brake set, try to turn
the 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 Transmission
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.
0 To check the parking brake: With the engine running
and transmission
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.

Downloaded from www.Manualslib.com manuals search engine Rear Axle Service
Check the gear lubricant level in the rear axle and add if
needed. See “Rear Axle”
in the Index. A fluid loss may
indicate a problem. Check the axle and repair
it if needed.
Drive Axle Service
Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
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.
