VEHICLE WARRANTY NUMBER

The vehicle warranty number is the first line of numbers and

letters appearing on the Warranty Plates (Fig. 1). The Warranty

Plate is riveted to the left front door lock face panel. The first

number indicates the model year. The letter following the model

year number indicates the manufacturing assembly plant. The next

two numbers designate the Body Serial Code followed by a letter

expressing the Engine Code. The group of six digits remaining on

the first line indicate the Consecutive Unit Number.

VEHICLE DATA

The vehicle data appears on the second or lower line on the

Warranty Plate. The first two numbers and a letter identify the

Body Style. A letter or a number appears next indicating the

Exterior Paint Color followed by a number-letter combination

designating the Interior Trim. To the right of this code appears the

Date Code indicating the date the car was manufactured. A two-

digit number next designates the district in which the car was

ordered and may appear in conjunction with a Domestic Special

Order or Foreign Special Order number when applicable. The final

two spaces indicate the Rear Axle Ratio (numbers for regular axles,

letters for locking-types) and the Transmission type (numbers for

manual,
letters for automatic).

o'clock position on the steering wheel

rim.

3.
With the steel tape still hooked

to the brake pedal depress the brake

pedal by pressing downward on the

brake pedal effort gauge. Apply a 50

pound load to the center of the pedal

by observing the pressure gauge, and

measure the distance from the brake

pedal to the fixed reference point on

the steering wheel rim parallel to the

centerline of the steering column.

4.
The difference between the brake

pedal free height and the depressed

pedal measurement under a 50 pound

load should be within the specified

maximum pedal travel service specifi-

cation B in Fig. I.

5.
If the pedal travel is more than

the specified maximum shown in Fig.

1,
dimension C, make several sharp

reverse stops (equivalent to 50 pounds

pedal pressure) with a forward stop

before each. Move the vehicle in rev-

erse and forward for a distance of ap-

proximately ten feet; then, apply the

brakes sharply and hold the brake

pedal down until the vehicle is com-

pletely stopped. This will actuate the

brake self-adjusters. If these stops do

not bring the brake pedal travel within

specification, make several additional

forward and reverse stops as outlined

above.

6. If the second series of stops do

not bring the brake pedal travel within

specification, remove the brake drums

and check the brake adjusters to make

sure they are functioning. Check the

brake linings for wear or damage. Re-

pair or replace all worn or damaged

parts and non-functioning adjusters.

Adjust the brake lining outside diame-

ter to the approximate inside diameter

of the brake drum with Rotunda Tool

HRE-8650 (Fig. 12, Part 2-2).

7.
If all the brake adjusters, brake

drums and linings are functional and

the brake travel is not within specifi-

cations, check the pedal linkage for

missing or worn bushings, or loose at-

tachments. Bleed the brakes and cen-

tralize the differential valve.

POWER BRAKE

FUNCTIONAL TEST

1.
Check the hydraulic brake sys-

tem for leaks or insufficient fluid.

2.
With the transmission in neutral,

stop the engine and apply the parking

brake. Depress the brake pedal several

times to exhaust all vacuum in the

system.

3.
With the engine shut off and all

vacuum in the system exhausted, dep-

ress the pedal, and hold it in the ap-

plied position. Start the engine If theprocarmanuals.com

vacuum system is operating, the pedal

will tend to fall away under foot pres-

sure and less pressure will be required

to hold the pedal in the applied posi-

tion. If no action is felt, the vacuum

booster system is not functioning.

If the brake pedal movement feels

spongy, bleed the hydraulic system to

remove air from the system. Refer to

Hydraulic System Bleeding, Part 1,

Section 2.

VACUUM TESTS—VACUUM

RELEASE PARKING BRAKES

Visually check the operation of the

brake linkage as the brake pedal is

depressed. Then, check the operation

of the brake linkage when the manual

release lever is activiated. These

checks should indicate whether the

manual parking brake control linkage

is operating properly or requires re-

pair or adjustment due to inability of

the parking brake to hold against

moderate vehicle movement. Perform

tests of the parking brake system and

controls after making certain the link-

age and manual controls operate

properly.

When testing a parking brake vacu-

um release system, a minimum of 10

inches of vacuum (Hg.) should be

available at all points where vacuum is

applied. This can be checked with a

Rotunda Fuel Pump Tester Gauge

(ARE345) and two Distributor Tester

hose adapters (Marked Q) connected

together with a coupling. This allows

the Fuel Pump Tester Gauge hose to
be adapted to any other vacuum hose

or rubber connector in the vacuum

systems.

Failure to maintain 10 inches of

vacuum (Hg.) during vacuum system

tests could be caused by a loose hose

connection, resulting in a vacuum

leak. When checking for vacuum be-

tween two points, trace the hose along

the entire routing to be sure it is not

crossed with another hose and con-

nected to the wrong connection.

All of the vacuum parking brake

control checks are to be performed

with the engine running at idle speed.

Leaks in the parking brake hoses or

a disconnected or improperly con-

nected hose can usually be found by

listening for a hissing sound along the

hose routings. Under no circumstances

should air pressure be applied to the

vacuum system as the actuator dia-

phragm in the parking brake vacuum

motor may be damaged.

1.
Start the engine and run it at

idle speed. With the transmission shift

control in neutral, depress the parking

brake pedal to apply the parking

brake. Move the transmission shift

control to D range and observe the

parking brake pedal to see that the

pedal moves upward and the parking

brake releases. If the parking brake

releases, the parking brake vacuum

control is working properly.

2.
If the parking brake does not re-

lease, test for vacuum at the steering

column neutral switch port in the

junction block, vacuum lines and the

parking brake release vacuum motor.

Use the Rotunda Vacuum and Fuel
Pump Tester 345. This can be accom-

plished by removing the hose from

each component and attaching it to

the vacuum gauge. Connect two dis-

tributor tester vacuum hose adapters

together with a coupling as a connec-

tor to attach the gauge. A minimum

of ten inches of vacuum is required to

actuate the parking brake vacuum

motor. Do not remove any of the vac-

uum hoses from the junction block

unless the junction block is being re-

placed, as the plastic nipples are thin

and very brittle and damage may re-

sult. If a minimum reading is not

present when checking each of the

aforementioned components, they

must be replaced.

ROAD TEST

A road test should be conducted

only when the operator is sure the

brakes will stop the vehicle.

If the road test reveals one or more

problem conditions, correct all mal-

functions of the vacuum system, brake

booster and hydraulic system prior to

removing brake drums, brake calipers,

brake shoes and linings or backing

plates.

ANTI-SKID CONTROL

SYSTEM TESTS

No adjustments or repairs are to be

performed on the skid control system.

Damaged or worn parts are to be re-

placed.

Refer to Ford Car and Truck Diag-

nosis Manual for Testing procedures.

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

assem-

bly remains
in the
original unit.

If
a
check
of the

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).

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.
