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
rod
assem-

bly remains
in the
original unit.

If
a
check
of the
push
rod
adjust-

ment
is
necessary,
the
push

length

may
be
verified with
a
push

1.
Disconnect the master cylinder

from the booster assembly and secure

away from the booster without discon-

necting the brake tubes.

2.
Reinstall the air filter assembly

on the booster if it was removed with

the master cylinder (Fig. 8).

3.
Install and tighten the master

cylinder retaining nuts to retain the

air filter assembly securely against the

booster body and to seal the booster

bellows against air leaks.

4.
Place the gauge against the

master cylinder mounting surface of

the air filter assembly.

5.
Adjust the push rod screw to

provide a slight tension against the

inner edge of the adjustment gauge

slot. (Approximately 5 pounds of ten-

sion against the push rod is required

to assure that the push rod is firmly

seated in the booster assembly.)

6. Remove the retaining nuts from

the booster master cylinder mounting

studs.

7.
Install the master cylinder on the

brake booster and tighten the retain-

ing nuts to the specified torque.

The push rod length verification of

the Bendix power brake booster

assemblies is accomplished as follows:

1.
Disconnect the master cylinder

from the booster assembly and secure

away from the booster without discon-

necting the brake tubes.

2.
Adjust the push rod screw to

provide a slight tension against the

inner edge of the adjustment gauge

slot. (Approximately 5 pounds of ten-
sion against the push rod is required

to assure that the push rod is firmly

seated in the booster assembly.) See

Figure 8.

3.
Install the master cylinder on the

brake booster and tighten the retain-

ing nuts to the specified torque.

Do not set up side forces on the

push rod as it may break the valve

plunger.

This is an approximate adjustment

only. To verify the adjustment, look

through the make-up (rear) port of the

master cylinder when installing the

master cylinder to the booster. The

master cylinder piston should not

move more than 0.015 inch as it con-

tacts the push rod. No movement

(exact contact) is ideal.

HYDRAULIC SYSTEM BLEEDING

AND CENTRALIZING OF THE

DIFFERENTIAL VALVE

When any part of the hydraulic sys-

tem has been disconnected for repair

or replacement, air may enter the sys-

tem and cause spongy pedal action.

Bleed the hydraulic system after it has

been properly connected, to be sure

that all air is expelled.

MANUAL BLEEDING

The Lincoln Continental hydraulic

brake system is to be bled only with

pressure bleeding equipment.

and rear) hydraulic brake systems are

individual systems and are bled separ-

ately. Bleed the longest line first on

the individual system being serviced.

During the complete bleeding opera-

tion,
DO NOT allow the reservoir to

run dry. Keep the master cylinder res-

ervoirs filled with Ford Fluid—Extra

Heavy Duty — Part Number C6AZ-

19542-A (ESA-M6C 25-A). The extra

heavy duty brake fluid is colored blue

for identification purposes. Do not

mix low temperature brake fluids with

the specified fluid during the bleeding

operations. Never re-use brake fluid

which has been drained from the hy-

draulic systems.

1.
If the master cylinder is

equipped with a bleed screw, loosen

the bleed screw. Push the brake pedal

down slowly through its full travel.

Close the bleeder fitting and return

the pedal to the fully released posi-

tion. Repeat this operation until fluid

is free of air bubbles, then tighten the

bleeder screw. Do not use the second-

ary piston stop screw, located on the

bottom of the master cylinder to bleed

the brake system. Loosening or re-

moving this screw could result in dam-

age to the secondary piston or stop

screw.

2.
To bleed the secondary (rear)

brake system, position a suitable 3/8

inch box wrench (Fig. 9) on the bleed-

er fitting on the brake wheel cylinder.

Attach a rubber drain tube to the

bleeder fitting. The end of the tube

should fit snugly around the bleeder

fitting.

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).

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

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
