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

DISASSEMBLY

1.
Remove the links and the rubber

boots from the ends of the brake cyl-

inder. Remove the pistons, cups, and

return spring from the cylinder bore

(Fig. 12).

2.
Remove the bleeder screw from

the cylinder.

INSPECTION

1.
Wash all parts in clean brake

fluid. Dry with compressed air.

2.
Replace scored pistons. Always

replace the rubber cups and dust

boots.
3.
Inspect the cylinder bore for

score marks or rust. If either condi-

tion is present the cylinder bore must

be honed. However, the cylinder

should not be honed more than 0.003

inch beyond its original diameter.

4.
Check the bleeder hole to be sure

that it is open.

ASSEMBLY

1.
Apply a light coating of heavy-

duty brake fluip! to all internal parts.

2.
Thread the bleeder screw into the

cylinder and tighten securely.

3.
Insert the return spring, cups,

and pistons into their respective posi-

tions in the cylinder bore (Fig. 12).
Place a boot over each end of the cyl-

inder. Bleed the brake system.

HYDRAULIC LINE REPAIR

Steel tubing is used throughout the

brake system with the exception of the

flexible hoses at the front wheels and

at the fear axle housing brake tube

connection (Figs. 17 thru 21).

Always bleed the applicable pri-

mary or secondary brake system after

primary or secondary brake system

hose or line replacement. Centralize

the pressure differential valve after

bleeding the system.

BRAKE TUBE

REPLACEMENT

If a section of the brake tubing be-

comes damaged, the entire section

should be replaced with tubing of the

same type, size, shape and length.

Copper tubing should not be used in a

hydraulic system. When bending

brake tubing to fit underbody or rear

axle contours, be careful not to kink

or crack the tube.

All brake tubing should be double

flared properly to provide good leak-

proof connections. Clean the brake

tubing by flushing with clean brake

fluid before installation.

When connecting a tube to a hose,

tube connector, or brake cylinder,

tighten the tube fitting nut to specified

torque with Milbar tool 1112-144 or

equivalent.

BRAKE HOSE

REPLACEMENT

A flexible brake hose should be re-

placed if it shows signs of softening,

cracking, or other damage.

When installing a new front brake

hose,
position the hose to avoid con-

tact with other chassis parts. Place a

new copper gasket over the hose fit-

ting and thread the hose assembly into

the front wheel cylinder. Engage the

opposite end of the hose to the brack-

et on the frame. Install the horsesho-

e-type retaining clip, and connect the

tube to the hose with the tube fitting

nut (Figs. 17 thru 21).

A rear brake hose should be in-

stalled so that it does not touch the

muffler outlet pipe or shock absorber.

Thread the hose into the rear brake

tube connector. Engage the front end

of the hose to the bracket on the

frame. Install the horseshoe-type re-

taining clip, and connect the tube to

the hose with the tube fitting nut.procarmanuals.com

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.

MAJOR REPAIR OPERATIONS

BRAKE DRUM REFINISHING

Minor scores on a brake drum can

be removed with sandpaper. A drum

that is excessively scored or shows a

total indicator runout of over 0.007

inch should be turned down. Remove

only enough stock to eliminate the

scores and true up the drum. The refi-

nished diameter must not exceed 0.060

inch oversize.

Check the inside diameter of the

brake drum with a brake drum mi-

crometer (Tool FRE-14^1).

If the drum diameter is less than

0.030 inch oversize after refinishing^

standard lining may be installed. If

the drum diameter is 0.030—0.060

inch oversize after refinishing, oversize

lining must be installed.

After a drum is turned down, wipe

the refinished surface with a cloth

soaked in clean denatured alcohol. If

one drum is turned down, the opposite

drum on the same axle should also be

cut down to the same size.

ROTOR REFINISHING

Rotunda Disc Brake Attachment,

FRE-2249-2, is the only recommended

tool to refinish the disc brake rotors.

The step-by-step resurfacing procedure

provided with the tool must be ad-

hered to.

The finished braking surfaces of the

rotor must be flat and parallel within

0.0007 inch; lateral runout must not

exceed 0.003 inch total indicator read-

ing, and the surface finish of the brak-

ing surfaces are to be 80/15 micro

inches. The minimum limiting dimen-

sions (Figs. 11 and 12, Part 2-1) from

the inboard bearing cup to the out-

board rotor face and from the inboard

bearing cup to the inboard rotor face

must be observed when removing ma-

terial from the rotor braking surfaces.

On all models except Lincoln Con-

tinental, the limiting dimensions are to

be measured with a ball and gage bar

(Rotunda Kit FRE-70160).

BRAKE SHOE RELINING

Brake linings that are worn to with-

in 1/32 inch of the rivet head or are

less than 0.030 inch thick (bonded lin-

ing) or have been contaminated with

brake fluid, grease or oil must be re-

placed. Failure to replace worn linings

will result in a scored drum. When it
is necessary to replace linings, they

must also be replaced on the wheel on

the opposite side of the vehicle.

Inspect brake shoes for distortion,

cracks, or looseness. If this condition

exists,
the shoe must be discarded. Do

not attempt to repair a defective brake

shoe.

1.
Wash the brake shoes thoroughly

in a clean solvent. Remove all burrs

or rough spots from the shoes.

2.
Check the inside diameter of the

brake drum with a brake drum mi-

crometer (tool FRE-1431). If the di-

ameter is less than 0.030 inches over-

size,
standard lining may be installed.

If the diameter is 0.030—0.060 inches

oversize, oversize lining should be in-

stalled.

3.
Position the new lining on the

shoe.
Starting in the center, insert and

secure the rivets, working alternately

towards each end. Replacement lin-

ings are ground and no further grind-

ing is required.

4.
Check the clearance between the

shoe and lining. The lining must seat

tightly against the shoe with not more

than 0.008 inch clearance between any

two rivets.

9. Remove the rubber piston seals

from the grooves in the cylinder bores

by carefully inserting the point of a

small knife or other pointed instru-

ment under the seal and raising the

seal up far enough to be pulled out

with the fingers.

Cleaning and Inspection

Clean all metal parts with isopropyl

alcohol or a suitable solvent (Fig. 46).

Use clean, dry, compressed air to

clean out and dry the grooves and

passage ways. Be sure that the caliper
bore and component parts are com-

pletely free of any foreign material.

Check the cylinder bores and pis-

tons for damage or excessive wear.

Replace the piston if it is pitted,

scored, or the chrome plating is worn

off. Check the caliper dust boot re-

tainer for wear or damage.

Assembly

1.
Clamp the caliper in a vise and

secure it by the mounting flange on

the inboard housing.

2.
Apply a film of clean brake fluid
to new caliper piston seals and install

them in the grooves of the cylinder

bore.
The seal should be positioned at

one area in the groove and gently

worked around. Do not use the origi-

nal seals.

3.
Install the new dust boots by set-

ting the flanges squarely in the outer

grooves of the caliper bores.

4.
Coat the pistons with the speci-

fied fluid and install the pistons inPthe

cylinder bores. Spread the dust boots

over the pistons as they are installed.

Seat the dust boots in the piston

grooves.

5.
Coat the outside diameter of the

pistons with brake fluid and install

them in the cylinder bores so that the

open end of the piston and ihe boot

retaining groove face out of the bore.

To avoid cocking, locate the piston

squarely in the bore and apply a slow

steady pressure. If a piston will not

easily go all the way into the bore, re-

move it and thoroughly inspect the

cylinder bore, the piston seal and the

installation of the seal. If the piston

still will not go in with bore in good

condition and the piston seal properly

installed, use the tool shown in Fig.

45.
Rotate the piston with the tool

while pushing it inward at the same

time.

6. Carefully install four new dust

boots on the caliper housings and pis-

tons.
Be sure that each boot is fully

seated in the groove of its respective

caliper housing and piston (Fig. 46).

Do not use the original dust boots.

7.
Install the external transfer tube.

8. Install the flexible brake hose to

the caliper.

9. Install the caliper assembly on

the spindle, and install the shoe and

lining assemblies and the splash shield

as outlined in Section 2. Check the

caliper for fluid leaks under maximum

pedal pressures. Do not move the car

until a firm brake pedal is obtained.procarmanuals.com

DESCRIPTION

FRONT SUSPENSION

Each front wheel rotates
on a

spindle.
The
upper
and
lower ends
of

the spindle
are
attached
to
upper
and

lower ball joints which
are
mounted
to

an upper
and
lower
arm
respectively.

The upper
arm
pivots
on a
bushing

and shaft assembly which
is
bolted
to

the frame.
The
lower
arm
pivots
on a

bolt
in the
front crossmember (Figs.
1,

2
and 3). A
coil spring seats between

the lower (upper
on
Cougar, Fairlane,

Falcon, Montego
and
Mustang)
arm

and
the top of the
spring housing.
A

double action shock absorber
is
bolted

to
the arm and the top of the
spring

housing.
REAR SUSPENSION

FORD, MERCURY,

METEOR, THUNDERBIRD
AND

CONTINENTAL MARK
III

Each rear wheel,
hub, and
brake

drum assembly
is
bolted
to the
rear

axle shaft flange.
The
axle shaft
as-

sembly rotates
in the
rear axle hous-

ing.

The rear axle housing
is
suspended

from
the
frame
by a
coil spring
and

shock absorber
at
each side
of the ve-

hicle
and by
three arms
(one
upper

and
two
lower) which pivot
in the

frame members
(Fig.
4).

Each coil spring
is
mounted
be-

tween
a
lower seat, which
is
welded
to

the axle housing,
and an
upper seat

which
is
integral with
the
frame.
The upper
end
of
the
rear shock
ab-

sorber
is
attached
to the
spring upper

seat;
the
lower
end is
bolted
to a

bracket
on the
axle housing.

The upper suspension
arm
attaches

to
the
right side
of the
axle housing

through
an
eccentric pivot bolt
and a

bracket which
is
welded
to the top of

the housing.
The
forward
end of the

arm
is
connected
by a
pivot bolt
to

the frame crossmember.

Each lower suspension
arm
attaches

to
one end of the
axle housing

through
a
pivot bolt
and a
bracket

which
is
welded
to the
underside
of

the housing.
The
forward
end of the

arm
is
connected
by a
pivot bolt
to

the frame side member.

A track
bar is
connected between

the upper
arm
bracket
on the
axle

housing
and a
mounting bracket
on

the left frame side rail.

3 IN-VEHICLE ADJUSTMENTS AND REPAIRS

REGULATOR ADJUSTMENT HEIGHT CONTROL VALVE

The regulator may be adjusted if

the regulator pressure is under 100 psi

with the reservoir pressure at a mini-

mum of 140 psi. If the regulated pres-

sure exceeds 130 psi, the regulator

must be replaced.

To adjust the regulator, remove the

boot and reposition the sleeve and re-

tainer deeper into the body of the re-

gulator, using a deep well socket (Fig.

4).
If the regulator pressure remains

under 100 psi, replace regulator.
SILICONE FLUID

REPLACEMENT

If the height control valve time

delay does not fall within specifica-

tion, the silicone fluid must be re-

placed. Then repeat the time delay

test. If delay is still not within specifi-

cations, replace the height control

valve.

1.
Remove control valve and clean
the exterior of the valve thoroughly.

2.
Position the valve with delay

plug on top. Remove delay plug and

drain silicone fluid from the chamber.

Remove the O-ring from the chamber

(Fig. 5), and discard the O-ring.

3.
Remove the cover plate retaining

ring, using snap ring pliers. Remove

the delay cover from the valve body.

Remove the O-ring from the chamber,

and discard the O-ring.

4.
Place a new O-ring over the

delay plug and install the plug. Tor-

que the plug to 20-30 in-lbs. .

5.
Pour silicone fluid into the delay

piston chamber until fluid level is 5/16

inch below the top edge of the body.

Add or remove fluid with an eye drop-

per until the proper fluid level is

reached.

6. Hold the control valve body in a

vise with the delay chamber elevated

slightly. Carefully operate the lever to

purge trapped air from the fluid.
