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-

brake adjustment then connect the

parking brake cable to the parking

brake lever (Fig. 8).

4.
Install the shoe guide (anchor

pin) plate on the anchor pin when so

equipped.

5.
Place the cable eye over the an-

chor pin with the crimped side toward

the backing plate.

6. Install the primary shoe to an-

chor spring (Fig. 15).

H1391-A

FIG. 75—Retracting Spring

Installation

7.
Install the cable guide on the

secondary shoe web with the flanged

hole fitted into the hole in the second-

ary shoe web. Thread the cable

around the cable guide groove (Fig.

8).

It
is
imperative that
the
cable
be

positioned
in
this groove
and not be-

tween
the
guide
and the
shoe
web.

8.
Install the secondary shoe to an-

chor spring with the tool shown in

Fig. 15.

Be certain that
the
cable
eye is not

cocked
or
binding
on the
anchor
pin

when installed.
All
parts should
be
flat

on
the
anchor
pin.
Remove
the
brake

cylinder clamp.

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
the
automatic
ad-

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.
10.
Place the adjusting socket on

the screw and install this assembly be-

tween the shoe ends with the adjusting

screw toothed wheel nearest the sec-

ondary shoe.

11.
Hook the cable hook into the

hole in the adjusting lever. The adjust-

ing levers are stamped with an R or L

to indicate their installation on right

or left brake assembly (Fig. 16).

12.
Position the hooked end of the

ADJUSTING LEVER

IDENTIFICATION LINES

H1143-C

FIG. 16—Adjusting Screw
and

Lever Identification

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.

so that the plunger rests against the

inner side of the wheel rim adjacent to

the lower ball joint.

4.
Grasp the tire at the top and

bottom and slowly move the tire in

and out (Fig. 19). Note the reading

(radial play) on the dial indicator. If

the reading exceeds specifications

(Part 3-13), replace the lower ball

joint.

Cougar, Fairlane, Falcon,

Montego, Mustang

1.
Raise the vehicle on a frame

contact hoist or by floor jacks placed

beneath the underbody until the wheel

falls to the full down position.

2.
Ask an assistant to grasp the

lower edge of the tire and move the

wheel in and out.

3.
As the wheel is being moved in

and out, observe the lower end of the

spindle and the lower arm.

4.
Any movement between the

lower end of the spindle and the lower

arm indicates ball joint wear and loss

of preload. If any such movement is

observed, replace the lower arm.

During the foregoing check, the

upper ball joint will be unloaded and

may move. Disregard all such move-

ment of the upper ball joint. Also, do

not mistake loose wheel bearings for a

worn ball joint.

POWER STEERING GEAR

CLEANING

Disassembly and assembly of the

steering gear and. the sub-assemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost
importance. The bench, tools, and

parts must be kept clean at all times.

Thoroughly clean the exterior of the

unit with a suitable solvent and, when

necessary drain as much of the hy-

draulic fluid as possible. Handle all

parts very carefully to avoid nicks,

burrs,
scratches and dirt, which could

make the parts unfit for use.

Do not clean, wash or soak seals in

cleaning solvent.

INSPECTION

1.
Check the sector shaft contact

surface in the cover for wear. If worn,

replace the cover.

2.
Inspect the input shaft bearing

for cracked races and the balls for

looseness, wear, pitting, end play or

other damage. Check the fit of the

bearing on the input shaft. Replace

the bearing, if required.

3.
Inspect the valve housing for

wear, scoring or burrs.

4.
Inspect the tube seats in the

pressure and return ports in the valve

body for nicks, etc. If necessary, re-

move and replace.

5.
Check the sector shaft contact

surface in the housing for wear. If

worn, replace the bushing or the hous-

ing.

6. Check all fluid passages for ob-

struction or leakage.

7.
Inspect the steering gear housing

for cracks, stripped threads, and mat-

ing surfaces for burrs. Inspect the pis-

ton bore of the housing for scoring or

wear. If necessary, replace the hous-

ing.

8. Check the input shaft bearing

after installation to be sure that it ro-

tates freely.

9. If the valve spool is not free in

the valve housing, check for burrs at

the outward edges of the working

lands in the housing and remove with

a hard stone. Check the valve spool

for burrs and if burrs are found, stone

the valve in a radial direction only.

Check for freedom of the valve again.

10.
Check the piston rack teeth and

sector shaft teeth for nicks and burrs.

dure under Pinion Location.

REMOVABLE CARRIER

TYPE AXLE

The shim location for the removable

carrier type axle is between the pinion

retainer and the carrier (Fig. 13).

When adjusting this type carrier re-

ducing shim thickness will move the

pinion toward the ring gear; increas-

ing shim thickness will move the pi-

nion away from the ring gear (Fig.

13).

place the companion flange and check

the runout. If necessary, rotate the

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

flange, it will be necessary to replace

the ring and pinion gear, and repeat

the above checks until runout is within

Two separate adjustments affect pin-

They are pinion location and backlash

Individual differences in matching

the pinion for correct contact with the

ring gear.

When adjusting either type axle,

shim thickness should be increased or

reduced only as indicated by the tooth

The shim location for the integral

cone (Fig. 12). When adjusting this

type axle, increasing shim thickness

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

ADJUSTMENTS (ALL AXLES)

On a Light-Duty (WER) Axle, it is

necessary to remove the rear axle

shafts prior to performing the adjust-

ment procedures. Refer to Rear Axle

Shaft Wheel Bearing and Oil Seal Re-

placement—Light-Duty (WER), Axle,

Part 4-4, Section 2.

To secure a more uniform control

of differential side bearing preload in

service repairs, a dial indicator set-up

such as shown in Fig. 12 is used.

In both types of axle (Fig. 11 and

12),
the ring gear is moved away from

or toward the pinion as described in

the following procedure.

1.
Remove the adjusting nut locks,

loosen the differential bearing cap

bolts,
then torque the bolts to 15 ft-lbs

on integral carrier type axle; 20 ft-lbs

on removable carrier type axles before

making adjustments.

2.
The left adjusting nut is on the

ring gear side of the carrier. The right

nut is on the pinion side. Loosen the

right nut until it is away from the cup.

Tighten the left nut until the ring gear

is just forced into the pinion with

0.000 backlash then rotate the pinion

several revolutions to be sure no bind-

ing is evident. (Recheck the right nutprocarmanuals.com

CLEANING AND INSPECTION

INSPECTION BEFORE

DISASSEMBLY OF CARRIER

(ALL AXLES)

The differential case or carrier

should be inspected before any parts

are removed from it. These inspec-

tions can help to find the cause of the

trouble and to determine the correc-

tions needed.

Mount the carrier in the holding

fixture shown in Fig. 15. Wipe the lu-

bricant from the internal working

parts,
and visually inspect the parts

for wear or damage.

Tool-T57L-500-A

FIG. 15
— Bench
Fixture for

Carrier Overhaul—Typical

Rotate the gears to see if there is

any roughness which would indicate

damaged bearings or chipped gears.

Check the gear teeth for scoring or

signs of abnormal wear.

Set up a dial indicator (Fig. 16) and

check the backlash at several points

around the ring gear. Backlash should

be within specifications.
If no obvious defect is noted, check

the gear tooth contact.

To check the gear tooth contact,

paint the gear teeth with the special

compound furnished with each service

ring gear and pinion. A mixture that

is too wet will run and smear. Too dry

a mixture cannot be pressed out from

between the teeth.

As shown in Fig. 17, rotate the ring

gear (use a box wrench on the ring

gear attaching bolts for a lever) five

complete revolutions in both directions

or until a clear tooth contact pattern

is obtained.

7—Checking Gear Tooth

Contact—Typical

Certain types of gear tooth contact

patterns on the ring gear indicate in-

correct adjustment. Noise caused by

incorrect adjustment can often be cor-

rected by readjusting the gears. Ac-

ceptable patterns and the necessary

corrections are explained under Tooth

Contact Pattern Check in Section I.

Gear tooth runout can sometimes

be detected by an erratic pattern on

the teeth. However, a dial indicator

should be used to measure the runout

of the back face of the ring gear as

shown in Fig. 18. If this runout ex-

ceeds specifications, disassemble the

carrier and replace necessary parts as

indicated in Part 4-2, Section 4 and

Part 4-3, Section 4.
1699-A

FIG. 18 -Checking Ring Gear

Runout—Typical

Loosen the differential bearing cap

bolts,
and then torque them to 25 ft-

lbs.
Remove the adjusting nut locks.

Carefully loosen one of the adjusting

nuts to determine if any differential

bearing preload remains. If any pre-

load remains, the differential bearings

may be re-used, provided they are not

pitted or damaged.

INSPECTION AFTER

DISASSEMBLY OF CARRIER

(ALL AXLES)

Thoroughly clean all parts. Syn-

thetic seals must not he cleaned, soak-

ed or washed in cleaning solvents.

Always use clean solvent when clean-

ing hearings. Oil the bearings im-

mediately after cleaning to prevent rust-

ing. Inspect the parts for defects.

Clean the inside of the carrier before

rebuilding it. When a scored gear set

is replaced, the axle housing should he

washed thoroughly and steam cleaned.

This can onl\ be done effectively if the

axle shafts and shaft seals are re-

moved from the housing. Inspect indi-

vidual parts as outlined below.

GEARS

Examine the pinion and ring gear

teeth for scoring or excessive wear.

Extreme care must he taken not to

damage the pilot hearing surface of

the pinion.procarmanuals.com
