REMOVAL AND INSTALLATION
FRONT BRAKE DRUM
REMOVAL
1.
Raise the vehicle until the wheel
and tire clear the floor. Remove the
wheel cover or hub cap, and remove
the wheel and tire from the drum.
2.
Remove the grease cap from the
hub.
Remove the cotter pin, nut lock,
adjusting nut, and flat washer from
the spindle. Remove the outer bearing
cone and roller assembly.
3.
Pull the drum off the wheel
spindle.
4.
If the drum will not come off,
pry the rubber cover from the brake
backing plate. Insert a narrow screw-
driver through the slot and disengage
the adjusting lever from the adjusting
screw. While holding the adjusting
lever away from the screw, back off
the adjusting screw with the brake ad-
justing tool (Fig. 13). Be very careful
not to burr, chip, or damage the
notches in the adjusting screw; other-
wise the self-adjusting mechanism will
not function properly.
INSTALLATION
1.
If the drum is being replaced, re-
move the protective coating from the
new drum with carburetor degreaser.
Then, use sandpaper to insure that no
residue remains. Wipe the drum with
a cloth soaked with denatured alcohol.
Install new bearings and grease seal.
Pack the wheel bearings, install the
inner bearing cone and roller assembly

*>.
After removing the rear brake
secondary shoe, disassemble the park-
ing brake lever from the shoe by re-
moving the retaining clip and spring
washer (Fig. 8).
INSTALLATION
1.
Before installing the rear brake
shoes,
assemble the parking brake
lever to the secondary shoe and secure
with the spring washer and retaining
clip.
2.
Apply a light coating of high-
temperature grease at the points
where the brake shoes contact the
backing plate.
3.

backing plate and secure the assembly
with the hold down springs. On the
rear brake, install the parking brake
link and spring, back off the parkingprocarmanuals.com

that the tabs on the shoe flanges seat
fully against the caliper bridges (Fig.
25).
2.
Install the caliper splash shield
and secure the shield to the caliper
with two retaining bolts (Fig. 4).
3.
Pump the brake pedal several
times until a firm pedal is obtained
and the shoe and lining assemblies are
properly seated.
4.
Install the wheel and tire assem-
bly on the hub and rotor assembly.
5.
Check and refill the master cyl-
inder reservoir with specified brake
fluid as required.
6. Road test the car.
It should not be necessary to bleed
the system after a shoe and lining re-
placement.
FRONT WHEEL HUB AND
ROTOR ASSEMBLY-
DISC BRAKES
REMOVAL
1.
Remove the wheel and tire from
the hub (Figs. 23 and 24). Be careful
to avoid damage or interference with
the bleeder screw fitting. On Lincoln
Continental models be careful to avoid
damage to the caliper splash shield or
transfer tube.
2.
Remove the caliper assembly
from the spindle and the rotor. If the
caliper does not require servicing, it is
not necessary to disconnect the brake
hose or remove the caliper from the
vehicle. Position the caliper out of the
way, and support it with a wire to
avoid damaging the caliper or stretch-
ing the hose. Insert a clean cardboard
spacer between the linings to prevent
the piston from coming out of the cyl-
inder bore while the caliper is re-
moved.
Handle the rotor and caliper assem-
blies in such a way as to avoid defor-
mation of the rotor and nicking,
scratching or contamination of the
brake linings.
3.
Remove the grease cap from the
hub.
Remove the cotter pin, nut lock,
adjusting nut, and flat washer from
the spindle. Remove the outer bearing
cone and roller assembly.
4.
Remove the hub and rotor as-
sembly from the spindle.
INSTALLATION
1.
If the rotor is being replaced, re-
move the protective coating from the
new rotor with carburetor degreaser.
Pack a new set of bearings with speci-
fied grease (M-1C75B), and install the
inner bearing cone and roller assembly
in the inner cup. Pack grease lightly
between the lips of a new grease seal
and install the seal (Figs. 23 and 24).
If the original rotor is being in-
stalled, make sure that the grease in
the hub is clean and adequate, that
the inner bearing and grease seal are
lubricated and in good condition, and
that the rotor braking surfaces are
clean.
2.
Install the hub and rotor assem-
bly on the spindle.
3.
Lubricate and install the outer
wheel bearing, washer and adjusting
nut.
4.
Adjust the wheel bearings to
specification, and then install the nut
lock, cotter pin, and grease cap. The
wheel bearing adjustment is especially
important with disc brakes.
5. Mount the caliper assembly on
the spindle following the Disc Brake
Caliper Assembly Installation proce-
dure in this section.
DISC BRAKE ROTOR
SPLASH SHIELD
REMOVAL
1.
Remove the caliper and the hub
and rotor assembly as outlined under

(it is not necessary to disconnect hy-
draulic connections).
2.
Remove the three bolts that at-
tach the splash shield to the spindle,
and remove the shield (Figs. 23 and
24).
3.
Remove and discard the splash
shield to spindle gasket.
INSTALLATION
1.
Install a new splash shield to
spindle gasket.
2.
If the shield is bent, straighten it
out before installation. Position the
shield to the mounting bracket, install
the attaching bolts, nuts and torque
them to specification.
3.
Install the hub and rotor assem-
bly and the caliper as outlined under

subsequent transmission failure. Refer
to Linkage Adjustments in Part 7-2,
7-3 or 7-4 for detailed manual linkage
adjustment procedures.
CONTROL PRESSURE
CHECK
When the vacuum diaphragm unit is
operating properly and the downshift
linkage is adjusted properly, all the
transmission shifts (automatic and
kickdown) should occur within the
road speed limits specified in Part 7-5.
If the shifts do not occur within
limits or the transmission slips during
shift point, the following procedure is
suggested to determine engine, trans-
mission, linkage, vacuum diaphragm
unit or valve body problems.
1.
Using the automatic transmis-
sion tester (Fig. 4), attach the tachom-
eter to the engine and the vacuum
gauge to the transmission vacuum line
at the vacuum unit (Fig. 5).

2.
Attach the pressure gauge to the
control pressure outlet at the trans-
mission (Figs. '., and 7).
3.
Firmly apply the parking brake
and start the engine.
On a vehicle equipped with a vacu-
um brake release, apply the service
brakes. The parking brake can not be
used because the brake automatically

releases when the transmission selec-
tor lever is moved to a drive position.
4.
Adjust the engine idle speed lo
the specified rpm. If the engine idle
speed cannot be brought within limits
by adjustment at the carburetor idle
adjustment screw, check the throttle
and downshift linkage for a binding
condition. If the linkage is satisfacto-
ry, check for vacuum leaks in the
transmission diaphragm unit (Fig. 8
or 9) and its connecting tubes and
hoses.
Check all other vacuum oper-
ated units (such as the power brake)
for vacuum leaks.
