ROD

ADJUSTMENT

The push
rod is
provided with
an

adjustment screw
to
maintain
the cor-

rect relationship between
the
booster

control valve plunger
and the
master

cylinder.
If the
plunger
is too
long
it

will prevent
the
master cylinder piston

from completely releasing hydraulic

pressure
and can
cause
the
brakes
to

drag.
If the
plunger
is too
short
it
will

result
in
excess pedal travel
and an

undesirable clunk
in the
booster area.

The adjustment screw
is set to the

correct height
at the
time
of
original

assembly
of the
power unit. Under

normal service
the
adjustment screw

does
not
require
any
further attention

providing
the
original push
rod
assem-

bly remains
in the
original unit.

If
a
check
of the
push
rod
adjust-

ment
is
necessary,
the
push
rod
length

may
be
verified with
a
push
rod
length

gauge
and
measured with
the
engine

running

1.
Disconnect the master cylinder

from the booster assembly and secure

away from the booster without discon-

necting the brake tubes.

2.
Reinstall the air filter assembly

on the booster if it was removed with

the master cylinder (Fig. 8).

3.
Install and tighten the master

cylinder retaining nuts to retain the

air filter assembly securely against the

booster body and to seal the booster

bellows against air leaks.

4.
Place the gauge against the

master cylinder mounting surface of

the air filter assembly.

5.
Adjust the push rod screw to

provide a slight tension against the

inner edge of the adjustment gauge

slot. (Approximately 5 pounds of ten-

sion against the push rod is required

to assure that the push rod is firmly

seated in the booster assembly.)

6. Remove the retaining nuts from

the booster master cylinder mounting

studs.

7.
Install the master cylinder on the

brake booster and tighten the retain-

ing nuts to the specified torque.

The push rod length verification of

the Bendix power brake booster

assemblies is accomplished as follows:

1.
Disconnect the master cylinder

from the booster assembly and secure

away from the booster without discon-

necting the brake tubes.

2.
Adjust the push rod screw to

provide a slight tension against the

inner edge of the adjustment gauge

slot. (Approximately 5 pounds of ten-
sion against the push rod is required

to assure that the push rod is firmly

seated in the booster assembly.) See

Figure 8.

3.
Install the master cylinder on the

brake booster and tighten the retain-

ing nuts to the specified torque.

Do not set up side forces on the

push rod as it may break the valve

plunger.

This is an approximate adjustment

only. To verify the adjustment, look

through the make-up (rear) port of the

master cylinder when installing the

master cylinder to the booster. The

master cylinder piston should not

move more than 0.015 inch as it con-

tacts the push rod. No movement

(exact contact) is ideal.

HYDRAULIC SYSTEM BLEEDING

AND CENTRALIZING OF THE

DIFFERENTIAL VALVE

When any part of the hydraulic sys-

tem has been disconnected for repair

or replacement, air may enter the sys-

tem and cause spongy pedal action.

Bleed the hydraulic system after it has

been properly connected, to be sure

that all air is expelled.

MANUAL BLEEDING

The Lincoln Continental hydraulic

brake system is to be bled only with

pressure bleeding equipment.

and rear) hydraulic brake systems are

individual systems and are bled separ-

ately. Bleed the longest line first on

the individual system being serviced.

During the complete bleeding opera-

tion,
DO NOT allow the reservoir to

run dry. Keep the master cylinder res-

ervoirs filled with Ford Fluid—Extra

Heavy Duty — Part Number C6AZ-

19542-A (ESA-M6C 25-A). The extra

heavy duty brake fluid is colored blue

for identification purposes. Do not

mix low temperature brake fluids with

the specified fluid during the bleeding

operations. Never re-use brake fluid

which has been drained from the hy-

draulic systems.

1.
If the master cylinder is

equipped with a bleed screw, loosen

the bleed screw. Push the brake pedal

down slowly through its full travel.

Close the bleeder fitting and return

the pedal to the fully released posi-

tion. Repeat this operation until fluid

is free of air bubbles, then tighten the

bleeder screw. Do not use the second-

ary piston stop screw, located on the

bottom of the master cylinder to bleed

the brake system. Loosening or re-

moving this screw could result in dam-

age to the secondary piston or stop

screw.

2.
To bleed the secondary (rear)

brake system, position a suitable 3/8

inch box wrench (Fig. 9) on the bleed-

er fitting on the brake wheel cylinder.

Attach a rubber drain tube to the

bleeder fitting. The end of the tube

should fit snugly around the bleeder

fitting.

9. Apply high-temperature grease

(MIC-100-A) to the threads and the

socket end of the adjusting screw.

Turn the adjusting screw into the ad-

justing pivot nut to the limit of the

threads and then back off 1/2 turn.

Interchanging
the
brake shoe
ad-

justing screw assemblies from
one
side

of
the
vehicle
to the
other would cause

the brake shoes
to
retract rather than

expand each time

justing mechanism operated.
To pre-

vent installation on the wrong side of

the vehicle, the socket end of the ad-

justing screw is stamped with an R or

L (Fig. 16). The adjusting pivot nuts

can be distinguished by the number of

grooves machined around the body of

the nut. Two grooves on the nut indi-

cate a right thread; one groove indi-

cates a left thread.

adjuster spring completely into the

large hole in the primary shoe web.

The last coil of the spring should be at

the edge of the hole. Connect the loop

end of the spring to the adjuster lever

hole.

13.
Pull the adjuster lever, cable

and automatic adjuster spring down

and toward the rear to engage the

pivot hook in the large hole in the sec-

ondary shoe web (Fig. 8).

14.
After installation, check the ac-

tion of the adjuster by pulling the sec-

tion of the cable between the cable

guide and the anchor pin toward the

secondary shoe web far enough to lift

the lever past a tooth on the adjusting

screw wheel. The lever should snap

into position behind the next tooth,

and release of the cable should cause

the adjuster spring to return the lever

to its original position. This return ac-

tion of the lever will turn the adjusting

screw.one tooth.

If pulling the cable does not pro-

duce the action described, or if the

lever action is sluggish instead of posi-

tive and sharp, check the position of

the lever on the adjusting screw

toothed wheel. With the brake in a

vertical position (anchor at the top),

the lever should contact the adjusting

wheel 3/16 inch (plus or minus 1/32

inch) above the centerline of the

screw. If the contact point is below

this centerline, the lever will not lock

on the teeth in the adjusting screw

wheel, and the screw will not be turned
as the lever is actuated by the cable.

To determine the cause of this con-

dition:

a. Check the cable end fittings. The

cable should completely fill or extend

slightly beyond the crimped section of

the fittings. If it does not meet this

specification, possible damage is indi-

cated and the cable assembly should

be replaced.

b.
Check the cable length. On

Ford, Mercury, Meteor, Thunderbird,

Continental Mark III, and Lincoln

Continental models, the cable should

measure 11 1/8 inches (plus or minus

1/64 inch) from the end of the cable

anchor to the end of the cable hook.

On Fairlane, Montego, Falcon,

Mustang, and Cougar models the

cable should measure 8 13/32 inches

on 9 inch brakes or 9 3/4 inches on

10 inch brakes from the end of the

cable anchor to the end of the cable

hook.

c. Check the cable guide for dam-

age.
The cable groove should be paral-

lel to the shoe web, and the body of

the guide should lie flat against the

web.
Replace the guide if it shows

damage.

d. Check the pivot hook on the

lever. The hook surfaces should be

square with the body of the lever for

proper pivoting. Replace the lever if

the hook shows damage.

e. See that the adjusting; screw

socket is properly seated in the notch

in the shoe web.

POWER STEERING-

PRELIMINARY TESTS

The following preliminary checks

should always be made before per-

forming any operations.

AIR BLEEDING

Air in the power steering system

(shown by bubbles in the fluid) should

be bled. After making sure that the

reservoir is filled to specification (the

fluid must be at normal operating

temperature when the check is made),

turn the steering wheel through its full

travel three or four times. Do not hold

the wheels against their stops. Re-

check the fluid level.

CHECK FLUID LEVEL

Run the engine until the fluid is at

normal operating temperature. Then

turn the steering wheel all the way to

the left and right several times, and

shut off the engine.

Check the fluid level in the power

steering reservoir. The level must show

on the cross hatching between the bot-

tom of the dipstick and the full mark

(Fig. 1). If the level is low, add

enough automatic transmission fluid

C1AZ-19582-A to raise the level to

the F mark on the dipstick. Do not

overfill the reservoir.

CHECK PUMP BELT

If the pump belt is broken, glazed,

or worn, replace it with a new belt.

Use only the specified type of belt.

Refer to Part 3-13 for belt adjustment

procedure.

CHECK FOR FLUID

LEAKS

With the engine idling, turn the

steering wheel from stop to stop sever-

al times. Check all possible leakage

points. Tighten all loose fittings, and

replace any damaged lines or defective

seats.

CHECK TURNING EFFORT

With the front wheels properly al-

igned and tire pressures correct, check

the effort required to turn the steering

wheel.

HOISTING INSTRUCTIONS

Damage to steering linkage compo-

nents and front suspension struts may

occur if care is not exercised when po-

sitioning the hoist adapters of 2 post

hoists prior to lifting the vehicle.

If a 2 post hoist is used to lift the

vehicle, place the adapters under the

lower arms or the No. 1 crossmember.

Do not allow the adapters to contact

the steering linkage. If the adapters

are placed under the crossmember, a

1.
Position a support between the

upper arm and frame side rail as

shown in Figs. 8 and 9; then, raise the

vehicle and position safety stands.

2.
Remove the wheel and tire.

3.
Remove the cotter pin and nut

from the upper ball joint stud.

4.
Position the ball joint remover

tool as shown in Fig. 10. The tool

should seat firmly against the ends of

both studs, and not against the lower

stud nut. It may be necessary to re-

move the lower ball joint cotter pin if

it prevents the tool from seating on

the lower stud.

5.
Turn the tool with a wrench until

both studs are under tension, and

then, with a hammer, tap the spindle

Angle Adjustment

1.
Position the magnetized Tool

T68P-4602-A on a U-joint bearing

cap as shown in Fig. 15.

2.
With the tool suspended straight

down and the adjusting screw to the

left, adjust the dial on the tool until

the left-hand edge of the bubble is ex-

actly on the zero line.

3.
Position the vee magnet on the

drive shaft away from welds and bal-

ance weights (Fig. 15).

4.
Position the magnetized tool

(T68P-4602-A) on the vee magnet

with the adjusting screw to the left in

the same relative position as it was on

the bearing cap (Fig. 16).

5.
Read the position of the bubbles

left-hand edge on the scale to deter-

mine the drive shaft pinion angle. The

reading should be 3 1/2 degrees plus 1
degree on Ford, Mercury or Meteor

models, 7 1/4 degrees plus 3/4 degree

on Thunderbird or Continental Mark

III models.

Adjustment

If the pinion angle is not within

specifications, adjust the pinion angle

as follows:

The upper arm-to-axle housing bolt

and two eccentric washers form an ad-

justing cam mechanism (Fig. 17)

which will tilt the axle housing to the

required angle.

1.
Loosen the upper arm pivot bolt

nuts.

2.
If the angle is less than specifica-

tions,
rotate the adjusting cam for-

ward and recheck the angle. If the

angle is more than specification, ro-

tate the adjusting cam rearward and

recheck the angle.

3.
When the axle housing is adjust-

ed in such a way that the drive shaft

angle reading is within specification,

install new pivot bolt nuts and torque

to specification (Fig. 17).

4.
Lower the vehicle and road test

for proper axle operation.

REMOVAL AND INSTALLATION

HOISTING INSTRUCTIONS

Damage to steering linkage compo-

nents and front suspension struts may

occur if care is not exercised when po-

sitioning the hoist adapters of 2 post

hoists prior to lifting the vehicle.

If a 2 post hoist is used to lift the

vehicle, place the adapters under the

lower arms or the No. 1 crossmember.

Do not allow the adapters to contact

the steering linkage. If the adapters

are placed under the crossmember, a

piece of wood (2 x 4 x 16 inches)

should be placed on the hoist channel

between the adapters. This will pre-

vent the adapters from damaging the

front suspension struts.
