CENTRALIZING THE

PRESSURE DIFFERENTIAL

VALVE

After a failure of the primary (front

brake) or secondary (rear brake) sys-

tem has been repaired and bled, the

dual-brake warning light will usually

continue to be illuminated due to the

pressure differential valve remaining in

the off-center position.

To centralize the pressure differen-

tial valve and turn off the warning
light after a repair operation, a pres-

sure differential or unbalance condi-

tion must be created in the opposite

brake system from the one that was

repaired or bled last.

1.
Turn the ignition switch to the

ACC or ON position. Loosen the dif-

ferential valve assembly brake tube

nut at the outlet port on the opposite

side of the brake system that was

wheel balanced, repaired and/or bled

last. Depress the brake pedal slowly to

build line pressure until the pressure
differential valve is moved to a cen-

tralized position and the brake warn-

ing light goes out; then, immediately

tighten the outlet port tube nut.

2.
Check the fluid level in the mas-

ter cylinder reservoirs and fill them to

within 1/4 inch of the top with the

specified brake fluid, if necessary.

3.
Turn the ignition switch to the

OFF position.

4.
Before driving the vehicle, check

the operation of the brakes and be

sure that a firm pedal is obtained.

CLEANING AND INSPECTION

DISC BRAKES

1.
Remove the wheel and tire and

the shoe and lining assemblies as out-

lined in Part 2-2, Section 2.

2.
On all models except Lincoln

Continental, make thickness measure-

ments with a micrometer across the

thinnest section of the shoe and lining.

If the assembly has worn to a thick-

ness of 0.230-inch (shoe and lining to-

gether) or 0.030-inch (lining material

only) at any one of three measuring

locations or if there is more than

0.125 taper from end to end or if lin-

ing shows evidence of brake fluid con-

tamination, replace all (4) shoe and

lining assemblies on both front wheels.

On Lincoln Continental brakes

make three thickness measurements

with a micrometer across the middle

section of the shoe and lining. Take

one reading at each side and one in

the center. If the assembly has worn

to a thickness of 0.231 inch (shoe and

lining together) or 0.066 inch (lining

material only) at any one of the three

measuring locations, replace all (4)

shoe and lining assemblies on both

front wheels.

3.
Check the caliper to spindle at-

taching bolts torque. Torque them to

specification, if required.

4.
To check rotor runout, first

eliminate the wheel bearing end play

by tightening the adjusting nut. After

tightening the nut, check to see that

the rotor can still be rotated.

5.
Clamp a dial indicator to the

caliper housing so that the stylus con-

tact the rotor at a point approximate-

ly 1 inch from the outer edge. Rotate

the rotor and take an indicator read-

ing. If the reading exceeds 0.003 inch

total lateral runout on the indicator,

replace or resurface the disc brake

rotor. The following requirement must

be met when resurfacing disc brake

rotors:
Rotunda Disc Brake Attachment

FRE-2249-2 is the only approved tool

to be used to refinish the disc brake

rotors.
The step-by-step resurfacing

procedure provided with the tool must

be adhered to.

The finished braking surface of the

rotor must be flat and parallel within

0.0007 inch; lateral runout must not

exceed 0.003 inch total indicator

reading, braking surface are to be 80/15

micro inches.

On all models except Lincoln Con-

tinental the minimum limiting dimen-

sion from the inboard bearing cup to

the inboard rotor face and the mini-

mum rotor thickness dimension, must

be observed when removing material

from the rotor braking surfaces. A

ball and gage bar (Rotunda Kit FRE

70160) is to be used when checking

minimum dimensions (Fig. 11).

On Lincoln Continental models the

minimum limiting dimension (Fig. 12)

from the inboard bearing cup to the
inboard rotor face (dimension B)

and the outboard rotor surface and

the inboard bearing cup (dimension

A),
must be observed when remov-

ing material from the rotor braking

surfaces.

When the runout check is finished

be sure to adjust the bearings as out-

lined in Group 3, in order to prevent

bearing failure.

6. Check the rotor for scoring. Mi-

nor scores can be removed with a

fine emery cloth. If the rotor is ex-

cessively scored, refinish it as out-

lined in step 5 or replace the rotor,

if required.

7.
Visually check the caliper. If the

caliper housing is leaking it should be

replaced. If a seal is leaking the cali-

per must be disassembled and new

.seals installed. If a piston is seazed

in the bore a new caliper housing is

required.

On Lincoln Continental models the

two halves of the caliper assembly

should never be separated. Damage or

failure of one requires replacement of

both as a unit.

Check the brake hoses for signs of

cracking, leaks or abrasion. Replace

them if necessary.

DISC BRAKE SERVICE

PRECAUTIONS

1.
Grease or any other foreign ma-

terial must be kept off the caliper as-

sembly, surfaces of the rotor and ex-

ternal surfaces of the hub during serv-

ice operations. Handling of the rotor

and caliper assemblies should be done

in a way to avoid deformation of the

brake rotor and nicking or scratching

of brake linings.

2.
If a caliper piston is removed for

any reason, the piston seal must be re-

placed.

3.
During removal and installation

of a wheel assembly, exercise care not

to interfere with and damage the cali-procarmanuals.com

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.

ment. In the absence of such equip-

ment, portable equipment may be

used and the work may be performed

on a level floor. The floor area should

be level within 1/4 inch from front to

rear of the vehicle and within 1/8 inch

from side to side. Alignment height

spacers (Figs. 4, 8 and 9) are used to

check caster and camber. The spacers

should be omitted when checking toe-

in.

1.
Check the runout of each front

wheel and tire using a dial indicator

against the rim outer band. If the ru-

nout exceeds 1/8 inch, correction may

be made by rotating the wheel on the

drum. When the minimum runout has

been obtained, mark the point of

greatest runout so the wheels can be

positioned as shown in Fig. 10 when

checking the front end alignment.

Hold a piece of chalk against the

wheel rim or the tire sidewall while

spinning the wheels. The chalk will

mark the rim or tire at the point of

greatest runout.

2.
Drive the vehicle in a straight

line far enough to establish the

straight ahead position of the front

wheels, and then mark the steering

wheel hub and the steering column

collar (Fig. ll).Do not adjust the

steering wheel spoke position at this

time. If the front wheels are turned at

any time during the inspection, align

the marks to bring the wheels back to

the straight-ahead position.

3.
With the vehicle in position for

the front end alignment inspection and

adjustment, install the suspension

alignment spacers as follows to esta-

blish the curb height.

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.

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.

FLUSHING THE POWER

STEERING SYSTEM—ALL EXCEPT

LINCOLN CONTINENTAL AND

CONTINENTAL MARK III

Should it be necessary to replace an

inoperative power steering pump, the

need for flushing the steering system

is required when installing the new

pump.
1.
Remove the power steering pump

and remove the pulley as outlined in

Part 3-10.

2.
Install the pulley on a new

pump. Install the pump and connect

only the pressure hose to the pump

(Part 3-10).

3.
Place the fluid return line in a

suitable container and plug the reser-

voir return pipe.

4.
Fill the reservoir with lubricant

(C1AZ-19582-A).

5.
Disconnect the coil wire to pre-

vent the engine from starting and raise

the front wheels off the ground.

6. While approximately two quarts

of steering gear fluid are being poured

into the reservoir, turn the engine over

using the ignition key, at the same

time cycle the steering wheel from

stop to stop.

7.
As soon as all of the lubricant

has been poured in, turn off the igni-

tion key, and attach the coil wire.

8. Remove the plug from the reser-

voir return pipe, and attach the return

hose to the reservoir.

9. Check the reservoir fluid level; if

low, add fluid to the proper level. Do

not overfill.

10.
Lower the vehicle.

11.
Start the engine and cycle the

steering from stop to stop to expel

any trapped air from the system.

RELIEF VALVE PLUNGER

G1607-A

FIG.
20—Cleaning Pump Relief Valveprocarmanuals.com

03-01-10
Suspension — Steering, Wheels And Tires — General Service

03-01-10

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

TILT STEERING COLUMNS

The steering column
is of the col-

lapsible type
to
lessen
the
possibility

of injury
to the
driver
of the
vehicle

should
he
become involved
in an
acci-

dent.
The
lower
end of the
steering

column tube
at the
bellows area will

collapse approximately
six
inches

upon
a
hard impact.

The shift tube
and the
steering shaft

are provided with plastic dowels
and

will shear
and
allow them
to
collapse

in proportion
to the
outer tube upon

impact.

Once
the
steering column
has
been

collapsed,
a
complete
new
column
must
be
installed.

The tilt column features nine driv-

ing positions (four
up and
four down

from
a
center position).
The
.column

also features
a
turn signal switch with

a lane-changer position turn indicating

position
and
emergency warning flash-

er control.

TILT-AWAY STEERING COLUMNS

The tilt-away steering column
fea-

tures nine driving positions (four
up

and four down from
a
center position)

and
a
tilt-away position that
is
auto-

matically accomplished
on
Mustang

and Cougar models when
the
ignition

key
is
turned
to the
OFF
position
and

the left door
is
opened.
On
Thunder-

bird models,
the
tilt-away occurs when
the shift lever
is
placed
in
PARK
and

the driverns door
is
opened.

a
dial indi-

cator with
1.000
inch minimum travel,
and
a
cup-shaped dial indicator adapt-

er tool
(Fig. 6). To
fabricate
the

checking tool, modify
a

assembly
by
removing
two
bearing

cups that are opposite each other, and

cuttting
or
grinding
off
one
of
the uni-

versal joint bearing flanges (Fig. 6).

5.
Install
the
cup-shaped adapter
on

the dial indicator stem. Install
the
dial

indicator
on the
pinion retainer
or pi-

nion nose bumper bracket. Position

the indicator
to
allow
an
indication
at

the ends
of the

6. Turn
the
companion flange
so

that
the
dial indicator cup-type adapt-

er rests
on the
machined surface
of

the bearing
cup (Fig. 6).
Rotate
the

companion flange side-to-side slightly

to obtain
a
reading indicating that
the

bearing
cup
surface
is
perpendicular
to

the indicator cup-type adapter. This

will
be the
point
at
which
the
dial
in-

dicator
cup is
closest
to the
center
of

companion flange rotation.
It is
also

the point
at
which
the
dial indicator

hand will reverse direction
as
the com-

panion flange
is
turning.
Set the
dial

indicator
to
zero.
