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.

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

1 TESTING
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.

PUMP FLOW TEST
1.
Depending on the equipment
present on the vehicle (air condition-
ing, power brakes, standard transmis-
sion),
one of the following options
may be used to connect the pump
pressure and return hoses to the test
tool (T56L-3361O-D and T68L-
33610-A):
a. Disconnect the pressure and re-
turn lines at the power steering pump
(Fig. 2). Obtain a power steering re-
turn hose from stock and connect the
end with the fitting to the output fit-
ting of the tool using the
5/8-18
SAE
female, 1/4 N.P. thread male fitting
provided. The end of the stock hose
(without the fitting) should be con-
nected to the return tube of the pump.
Connect the pressure hose from the
tool to the outlet fitting of the pump.
b.
Disconnect the pressure line at
the pump and connect the pressure
line from the test tool to the outlet fit-
ting of the pump. Disconnect the re-
turn line at the gear and connect it to
the output fitting of the tool, using the
5/8-18
SAE female, 1/4 N.P. thread
male fitting provided.

type of equipment is used, follow the
installation and inspection instructions
provided by the equipment manufactu-
rer.
CASTER
Check the caster angle at each front
wheel.
The caster is the forward or rear-
ward tilt of the top of the wheel
spindle (Fig. 12). If the spindle tilts to
the rear, caster is positive. If the
spindle tilts to the front, caster is neg-
ative. The correct caster angle, or tilt,
is specified in Part 3-13.
On Mustang, Cougar, Fairlane,
Falcon and Montego vehicles, the
maximum caster difference for check-
ing purposes must not exceed one de-
gree.
If setting is necessary, then the
maximum difference must not exceed
1/2 degree. On all other vehicles, the
maximum caster difference must never
exceed 1/2 degree.
CAMBER
Check the camber angle at each
front wheel.
Camber is the amount the front
wheels are tilted at the top (Fig. 12).
If a wheel tilts outward, camber is
positive. If a wheel tilts inward, cam-
ber is negative. The correct camber
angle, or outward (positive) tilt is
specified in Part 3-13.
On Mustang, Cougar, Fairlane,
Falcon and Montego vehicles, the
maximum camber difference for
checking purposes must not exceed
one degree. If setting is necessary,
then the maximum difference must
not exceed 1/2 degree. On all other
vehicles, the maximum camber differ-
ence must never exceed 1/2 degree.
TOE-IN
Alignment height spacers should not
be used to check and adjust toe-in.
Toe-in should only be checked and ad-
justed after the caster and camber
have been adjusted to specifications.
Check the toe-in with the front
wheels in the straight-ahead position.
Run the engine so that the power
steering control valve will be in the
center (neutral) position (if so
equipped). Measure the distance be-
tween the extreme front and also be-
tween the extreme rear of both front
wheels. The difference between these
two distances is the toe-in or toe-out.
Correct toe-in, or inward pointing
of both front wheels at the front is
specified in Part 3-13.
FRONT WHEEL
TURNING ANGLE
When the inside wheel is turned 20
degrees, the turning angle of the out-
side wheel should be as specified in
Part 3-13. The turning angle cannot
be adjusted directly, because it is a re-
sult of the combination of caster,
camber, and toe-in adjustments and
should, therefore, be measured only
after these adjustments have been
made. If the turning angle does not
measure to specifications, check the
spindle or other suspension parts for a
bent condition.

Slowly turn the steering wheel to
the left stop, lubricant should rise
within the lower cover bolt hole; then
slowly turn the steering wheel to the
right stop, lubricant should rise within
the filler plug hole. If lubricant does
not rise in both the cover bolt hole
and the filler plug hole, add lubricant
until it comes out both holes during
this check.
6. Install the lower (upper on
Mustang and Cougar) cover- to-
housing attaching bolt and the filler
plug.
CLEANING
AND
INSPECTION
FRONT
END
GENERAL
INSPECTION
Do not check and adjust front
wheel alignment without first making
the following inspection for front-end
damage, or wear.
1.
Check for specified air pressures
in all four tires.
2.
Raise the front of the vehicle off
the floor. Shake each front wheel
grasping the upper and lower surfaces
of the tire. Check the front suspension
ball joints and mountings for loose-
ness,
wear, and damage. Check the
brake backing plate mountings. Tor-
que all loose nuts and bolts to specifi-
cation. Replace all worn parts as out-
lined in Part 3-2.
3.
Check the steering gear mount-
ings and all steering linkage connec-
tions for looseness. Torque all mount-
ings to specifications. If any of the
linkage is worn or bent, replace the
parts as outlined in Part 3-5.
4.
Check the front wheel bearings.
If any in-and-out free play is noticed,
adjust the bearings to specifications.
Replace worn or damaged bearings as
outlined in Part 3-12.
5.
Spin each front wheel with a
wheel spinner, and check and balance
each wheel as required.
6. Check the action of the shock
absorbers. If the shock absorbers are
not in good condition, the vehicle may
not settle in a normal, level position,
and front wheel alignment may be af-
fected.
WHEEL INSPECTION
Wheel hub nuts should be inspected
and tightened to specification at pre-
delivery. Loose wheel hub nuts may
cause shimmy and vibration. Elongat-
ed stud holes in the wheels may also
result from loose hub nuts.
Keep the wheels and hubs clean.
Stones wedged between the wheel and
drum and lumps of mud or grease can
unbalance a wheel and tire.
Check for damage that would affect
the runout of the wheels. Wobble or
shimmy caused by a damaged wheel
will eventually damage the wheel bear-
ings.
Inspect the wheel rims for dents
that could permit air to leak from the
tires.

1.
Raise the vehicle and place floor
jacks beneath the lower arms.
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 upper end of the
spindle and the upper arm.
4.
Any movement between the
upper end of the spindle and the upper
arm indicates ball joint wear and loss
of preload. If any such movement is
observed, replace the upper ball joint.
During
the
foregoing
check,
the
lower ball joint will
be
unloaded

The following procedure should be
followed when cleaning the relief valve
which is a part of the pump valve as-
sembly.
1.
Using a punch or rod of suitable
diameter, apply an even pressure in a
straight line to the tip of the relief
valve pin (Fig. 20). Depress the valve
two or three times to exhaust the oil
which is trapped in the assembly. Do
not hammer on the valve pin or hous-
ing.
2.
Submerge the assembly in a con-
tainer of clean solvent. Again applying
an even pressure to the tip of the relief
valve pin, (a sudden strong force could
push the pin through the relief valve
spool) move the valve in and out sev-
eral times, thereby thoroughly flushing
the assembly. Pressure created within
the valve bore when the valve is moved
inward should force the cleaning fluid
out through the sensing orifice. If this
does not occur, the sensing orifice
should be cleaned with a piece of wire.
The valve must move freely and even-
ly. If the pin is bent or damaged, or if
the valve binds, the pump valve must
be replaced.
INSPECTION
The following describes the compo-
nents of the power steering pump
which must be replaced regardless of
condition and how to determine when
other components should be replaced.
The outlet fitting hex nut may be
reused if the corners of the hex are
not rounded. The housing bolts may
be reused if the threads are not dam-
aged.
All gaskets and seals must be re-
placed with new components except
the rotor shaft seal which should be
reused unless it was leaking.
The reservoir assembly may be
reused if the reservoir seal and gasket
areas are not damaged (dents, scratch-
es,
etc.). The soldered joints of the re-
turn and fill tubes must not be loose
or bent. Be sure to check for a broken
baffle.
The housing or housing assembly
may be reused if there is no damage
(scratches, etc.) at reservoir gasket,
outlet fitting or cover seal areas.
If the outlet fitting is damaged, the
pump housing must be replaced. The
pressure plate springs may be reused
providing they are not bent, broken or
have not taken a set.
Do not reuse the retainer end plate
if it is burred or damaged. The upper
pressure plate may be reused if there
is no scoring on the wear surface. It is
acceptable to polish the phosphate
coating.
The rotor and cam assembly can be
reused if there is no wear other than
the removal of the phosphate coating
on the cam contour. Do not disas-
semble the rotor and cam assembly.
Push the rotor part way out the cam
insert taking care not to let the slip-
pers and springs fall out. Check the
cam ID for scoring and burning.
Check the rotor faces and OD for
scoring and chipping. Do not attempt
to repair or refinish the lower and
upper pressure plates, cam or rotor
assembly. When wear or burning is
encountered, replace, them with new
components.
Install a new rotor and cam assem-
bly if the slippers are worn. Replace
the springs if they are bent or broken.
Polishing the phosphate coating of the
slipper sealing surface is permissable.
The rotor shaft can be reused if the
front and rear thrust faces, the bush-
ing diameter and the shaft seal diame-
ter are not excessively worn or scored.
The housing plate and bushing as-
sembly may be reused if all of the
threaded holes are not damaged
beyond repair and the bushing diame-
ter is not scored or worn .0005 inch
over the maximum dimension of .6897
inch. Threaded holes can be repaired
by drilling out the damaged threads
and installing a helicoil insert. If the
bushing is scored or excessively worn,
a new plate and bushing assembly
must be installed.
With Tool T69P-3D608-A (using a
dial indicator) check the squareness of
the fixed dowel pin in the plate (Fig.
21).
The pin must be square with the
adjacent surface within .001 inch per
inch through a 180 degree arch.
A bent or broken dowel pin can be
replaced as follows:
1.
Hold the plate assembly in a
horizontal position and grip at least
an inch of the dowel pin in a vise. Tap
the plate with a plastic or a rubber
hammer to pull the pin from the
plate.
2.
Insert the support guide (Tool
T69P-3D608-B) over a dowel pin (Fig.
22) and press the pin into the plate to
a height of 1.68 inch (See Fig. 23).
The support guide tool will serve as a
stop guide. Be careful not to bend the
new dowel pin during installation.
3.
Again use Tool T69P-3D608-A
(with a dial indicaator) to check the
dowel pin squareness as outlined
above.

3.
Inspect the rotor, rollers, cam
ring, pressure plate, cover, and bush-
ing in the pressure plate for wear or
scoring. If damaged, replacement of
the pump (less housing) is required.
4.
Make sure the inner faces of the
cover and the housing are free of
paint, nicks, or burrs. Check all fluid
passages for restrictions.
5.
Inspect the valving surfaces
(areas where the rotor and rollers con-
tact) for wear or scoring. Replace the
pressure plate or the cover if worn or
scored. Inspect the bushing in the
pressure plate for wear or scoring, and
replace the plate if necessary.
6. Inspect the control valve for
scores, nicks, or burred edges. Re-
place the valve if damaged. Do not dis-
assemble the valve. Check the valve
for free movement in the housing
bore.
7.
Inspect the tube seat in the hous-
ing. If damaged, remove it with an
E-Z-Out and install a new seat.
SHOCK ABSORBER CHECKS
All vehicles are equipped with hy-
draulic shock absorbers of the direct-
acting type and are nonadjustable and
nonrefillable. They cannot be repaired.
Before replacing a shock absorber,
check the action of the shock absor-
bers as follows:
ON VEHICLE TESTS
1.
Check the shock absorber to be
sure it is securely and properly in-
stalled. Check the shock absorber in-
sulators for damage and wear.
Replace any defective insulators and
tighten attachments to the specified
torque (on a shock absorber which in-
corporates integral insulators, replace
the shock absorbers).
2.
Inspect the shock absorber for
evidence of fluid leakage. A light film
of fluid is permissible. Be sure any
fluid observed is not from sources
other than the shock absorber.
Replace the shock absorber if leak-
age is severe.
3.
Disconnect the lower end of the
shock absorber. Extend and compress
the shock absorber as fast as possible,
using as much travel as possible.
Action should become smooth and
uniform throughout each stroke.
Higher resistance on extension than
on compression is a normal condition.
Faint swish noises are also normal.
Remove the shock absorber for a
bench test if action is erratic. If the
action is smooth, but the shock absor-
bers are suspected of being weak fol-
low step 4:
4.
Repeat step 3 on the mating
shock absorber installed on the oppo-
site side of the vehicle, and compare
results of both tests. If the action is
similar, it is unlikely that either shock
absorber is defective. Reconnect both
shock absorbers.
Replace the shock absorber having
the lower resistance. Ensure that the
part number of the replacement is the
same as that of the original shock ab-
sorber. The replacement shock absor-
ber resistance will appear to be higher
than either original due to initial fric-
tion of the rod seal.
BENCH TEST
With the shock absorber right side
up (as installed in vehicle), extend it
fully. Then turn the shock absorber
upside down and fully compress it.
Repeat this procedure at least three
times to ensure that any entrapped air
has been expelled. Now place the
shock absorber right side up in a vise,
and hand stroke the shock absorber as
described in On Vehicle Tests, step 3.
If action is not now smooth and uni-
form, install a new shock absorber.procarmanuals.com
