FIG. 10—Parking Brake Control Assembly

With Manual Release—Typical

power unit with mounting bracket is

riveted to the control assembly. The

vacuum actuated piston within the

unit is connected by a rod to the

upper end of the release lever (Fig. 9).

The lower end of the release lever ex-

tends out for alternate manual release
in the event of vacuum power failure

or for optional manual release at any

time.

Hoses connect the power unit and

the engine manifold to a vacuum re-

lease valve in the transmission neutral

safety switch.
The anti-skid control system con-

sists of three major components (Fig.

39).
Mechanically driven electromag-

netic sensors at each rear wheel; an

electronic control module mounted

under the glove box; a vacuum pow-

ered actuator attached to a bracket on

the inside of the right front frame rail

under the toe board.

The sensors consist of steel rings

having teeth on their outer diameters,

pressed on each axle shaft just out-

board of the wheel bearing. The teeth

rotate past corresponding teeth on the

inside diameter of stationary steel

rings mounted in the bearing retain-

ers.
Also mounted in the retainers, are

ring-shaped permanent magnets and

coils of wire. Two wires from each

sensor connect the sensors to the con-

trol module.

The control module consists of solid

state electronic components sealed in

a container. It is connected to the sen-

sors and to a solenoid on the actuator.

The actuator is similar to a vacuum

brake booster and consists of three

parts.
A chamber divided by a vacuum

suspended diaphragm; a hydraulic cyl-

inder connected to the diaphragm; and

a solenoid connected electrically to the

control module.

IN-VEHICLE ADJUSTMENTS AND REPAIRS

After any brake service work, ob-

tain a firm brake pedal before moving

the vehicle. Riding the brake pedal

(common on left foot application)

should be avoided when driving the

vehicle.

BRAKE SHOE ADJUSTMENTS—

DRUM BRAKES

The hydraulic drum brakes are

self-adjusting and require a manual

adjustment only after the brake shoes

have been relined, replaced, or when

the length of the adjusting screw has

been changed while performing some

other service operation. The manual

adjustment is performed with the

drums removed, using the tool and the

procedure detailed below.

When adjusting the rear brake

shoes,
check the parking brake cables

for proper adjustment. Make sure that

the equalizer operates freely.
To adjust the brake shoes:

1.
Use Rotunda Tool HRE 8650,

(Fig. 11) to determine the inside diam-

eter of the drum braking surface.

2.
Reverse the tool as shown in Fig.

11 and adjust the brake shoe diameter

to fit the gauge. Hold the automatic

adjusting lever out of engagement

while rotating the adjusting screw, to

prevent burring the screw slots. Make

sure the adjusting screw rotates freely.

If necessary, lubricate the adjusting

screw threads with a thin, uniform

coating of MIC-100-A.

3.
Rotate Tool HRE 8650 around

the brake shoes to be sure of the set-

ting.

4.
Apply a small quantity of high

temperature grease to the points

where the shoes contact the backing

plate, being careful not to get the lu-

bricant on the linings.

5. Install the drums. Install Tinner-

man nuts and tighten securely.

6. Install the wheels on the drums
and tighten the nuts to specification.

7.
Complete the adjustment by

applying the brakes several times with

a minimum of 50 lbs pressure on the

pedal while backing the vehicle. After

each stop the vehicle must be moved

forward.

8. After the brake shoes have been

properly adjusted, check the operation

of the brakes by making several stops

while operating in a forward direction.

WHEEL CYLINDER REPAIR-

DRUM BRAKE

Wheel cylinders should not be di-

sassembled unless they are leaking or

unless new cups and boots are to be

installed. It is not necessary to remove

the brake cylinder from the backing

plate to disassemble, inspect, or hone

and overhaul the cylinder. Removal is

necessary only when the cylinder is

damaged or scored beyond repair.procarmanuals.com

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.

Three different three-speed trans-

missions are used. The C4 Automatic,

C6 Automatic and the FMX Auto-

matic. Part 7-1 covers testing, com-
mon adjustments and repairs, and

cleaning and inspection for the three

l
AUTOMATIC TRANSMISSION TESTS

When diagnosing transmission

problems, refer to the Ford Car and

Truck Diagnosis Manual for the de-

tailed information on the items that

could be causing the problem.

The following preliminary checks

should be made before proceeding

with other diagnosis checks.

TRANSMISSION FLUID LEVEL

CHECK

1.
Make sure that the vehicle is

standing level. Then firmly apply the

parking brake.

2.
Run the engine at normal idle

speed. If the transmission fluid is cold

run the engine at fast idle speed

(about 1200 rpm) until the fluid reach-

es its normal operating temperature.

When the fluid is warm, slow the en-

gine down to normal idle speed.

3.
On a vehicle equipped with a

vacuum brake release, disconnect the

release line and plug the end of the
line;
otherwise the parking brake will

not hold the transmission in any drive

position.

4.
Shift the selector lever through

all positions, and place the lever at P.

Do not turn off the engine during the

fluid level checks.

5.
Clean all dirt from the transmis-

sion fluid dipstick cap before remov-

ing the dipstick from the filler tube.

6. Pull the dipstick out of the tube,

wipe it clean, and push it all the way

back into the tube. Be sure it is prop-

erly seated.

7.
Pull the dipstick out of the tube

again, and check the fluid level. The

fluid level should be above the ADD

mark. If necessary, add enough fluid

to the transmission through the filler

tube to bring the level between the

ADD and FULL marks on the dip-

stick. Do not overfill the transmission.

Install the dipstick, making sure it is

fully seated in the tube.
8. Connect the vacuum brake re-

lease line if so equipped, and test it

for proper operation.

FLUID AERATION CHECK

A fluid level that is too high will

cause the fluid to become aerated:

Aerated fluid will cause low control

pressure, and the aerated fluid may be

forced out the vent.

Check the transmission fluid level.

Low fluid level can affect the opera-

tion of the transmission, and may in-

dicate fluid leaks that could cause

transmission damage.

TRANSMISSION FLUID

LEAKAGE CHECKS

Check the speedometer cable con-

nection at the transmission. Replace

the rubber seal if necessary.

Leakage at the oil pan gasket often

can be stopped by tightening the at-
