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.
