per splash shield or the bleeder screw

fitting.

4.
Front wheel bearing end play is

critical and must be within specifica-

tions.

5.
Be sure the vehicle is centered on

the hoist before servicing any front

end components, to avoid bending or

damaging the rotor splash shield on

full right or left wheel turns.

6. The proportioning valve should

not be disassembled or adjustments

attempted on it.

7.
Riding of the brake pedal (com-

mon on left foot applications) should

be avoided during vehicle operation.

8. The wheel and tire must be re-

moved ' separately from the brake

rotor, unlike drum brakes where the
wheel, tire and drum are removed as a

unit.

9. On floating caliper type disc

brakes whenever the caliper is re-

moved the caliper locating pins should

be inspected for wear or damage.

10.
On floating caliper type disc

brakes, the caliper assembly must be

removed from the spindle prior to re-

moval of the shoe and lining assem-

blies.

11.
On floating caliper type disc

brakes the calipers must not be inter-

changed from one side to the other.

When the caliper is installed on its

proper anchor plate and spindle, the

bleeder screw will point to the rear of

the vehicle (Fig. 22). If a caliper is in-

stalled on the wrong side of the vehi-

cle,
it is not possible to bleed the sys-

tem properly.

12.
Do not attempt to clean or re-

store oil or grease soaked brake lin-

ings.
When contaminated linings are

found, brake linings must be replaced

in complete axle sets.

DRUM BRAKES

1.
Remove the wheel from the

drum, and remove the drum as out-

lined in Part 2-2, Section 2.

2.
Brush all dust from the backing

plates and interior of the brake

drums.

3.
Inspect the brake shoes for ex-

cessive lining wear or shoe damage. If

the lining is worn within 1/32 inch of

the rivet heads or if the shoes are

damaged, they must be replaced. Re-

place any lining that had been con-

taminated with oil, grease or brake
fluid. Replace lining in axle sets. Prior

to replacement of lining, the drum di-

ameter should be checked to deter-

mine if oversize linings must be in-

stalled.

4.
Check the condition of brake

shoes,
retracting springs, hold-down

springs, and drum for signs of over-

heating. If the shoes have a slight blue

coloring, indicating overheating, re-

placement of the retracting and hold-.

down springs is strongly recommended.

Overheated springs lose their pull and

could cause the new lining i:o wear

prematurely, if they are not replaced.

5. If the vehicle has 30,000 or more

miles of operation on the brake linings

or signs of overheating are present

when relining brakes, the wheel cylin-

ders should be disassembled and in-

spected for wear and entrance of dirt

into the cylinder. The cylinder cups

should be replaced, thus avoiding fu-

ture problems.

6. Inspect all other brake parts and

replace any that are worn or dam-

aged.

7.
Inspect the brake drum and, if

necessary, refinish. Refer to Part 2-2,

Section 4 for refinishing.

BRAKE BOOSTER

Check the booster operation as

noted in Part 2-1, Section 1, Power

Brake Functional Test. If the brake

booster is damaged or defective, re-

place it with a new booster. The brake

booster is serviced only as an assem-

DRIVESHAFT BALANCING

(SINGLE UNIVERSAL JOINT)

If rotating
the
driveshaft
180 de-

grees does
not
eliminate vibration,
the

driveshaft
may be
balanced using
the

following procedure:

1.
Place
the
vehicle
on a
twin post

hoist
so
that
the
rear
of the
vehicle
is

supported
on the
rear axle housing

with
the
wheels free
to
rotate.

2.
With
the
driveshaft rotating
at a

speedometer speed
of
40-50
mph,
carefully bring
a
crayon
or
colored

pencil
up
until
it
just barely contacts

the rearward
end of
driveshaft
(Fig.

6).
The
mark made
by the
crayon
or

pencil will indicate
the
heavy side
of

the shaft. Care should
be
exercised

when working near
the
balance

weights
to
prevent injury
to the
hands.

3.
Install
two
Whittek type hose

clamps
on the
driveshaft
so
that
the

heads
are
located
180
degrees from

the crayon marking
(Fig. 7).
Tighten

the clamps.
4.
Run the
vehicle
up to
65-70
mph

speedometer speed.
If no
vibration
is

felt, lower
the
vehicle
and
road test.
If

unbalance still exists rotate
the
clamp

heads approximately
45
degrees away

from each other
and
test
for
vibration

(Fig.
8).

5.
Continue
to
rotate
the
clamp

heads apart
in
smaller amounts until

vibration
is
eliminated.
To
prevent

overheating,
do not run the
vehicle

on
the
hoist
for an
extended period.
