1 BRAKE SYSTEM TESTS
Always check
the
fluid level
in the
master cylinder before performing
the
test procedures.
If the
fluid level
is not
within
1/4
inch
of the top of the mas-
ter cylinder reservoirs,
add
Ford
Brake Fluid
—
Extra Heavy Duty —
Part Number C6AZ-19542-A
(ESA-
M6C25-A)
or
equivalent
for all
brake
applications.
The
extra heavy duty
brake fluid
is
colored blue
for
identifi-
cation purposes.
Do not mix low tem-
perature brake fluids with
the
speci-
fied brake fluid.
Should
one of the
wheel brakes
be
locked
and the
vehicle must
be
moved,
open
the
bleeder screw long enough
to
let
out a few
drops
of
brake fluid.
This bleeding operation will release
the brakes
but
will
not
correct
the
cause
of
trouble.

3.
With the steel tape still hooked
to the brake pedal depress the brake
pedal by pressing downward on the
brake pedal effort gauge. Apply a 50
pound load to the center of the pedal
by observing the pressure gauge, and
measure the distance from the brake
pedal to the fixed reference point on
the steering wheel rim parallel to the
centerline of the steering column.
4.
The difference between the brake
pedal free height and the depressed
pedal measurement under a 50 pound
load should be within the specified
maximum pedal travel service specifi-
cation B in Fig. I.
5.
If the pedal travel is more than
the specified maximum shown in Fig.
1,
dimension C, make several sharp
reverse stops (equivalent to 50 pounds
pedal pressure) with a forward stop
before each. Move the vehicle in rev-
erse and forward for a distance of ap-
proximately ten feet; then, apply the
brakes sharply and hold the brake
pedal down until the vehicle is com-
pletely stopped. This will actuate the
brake self-adjusters. If these stops do
not bring the brake pedal travel within
specification, make several additional
forward and reverse stops as outlined
above.
6. If the second series of stops do
not bring the brake pedal travel within
specification, remove the brake drums
and check the brake adjusters to make
sure they are functioning. Check the
brake linings for wear or damage. Re-
pair or replace all worn or damaged
parts and non-functioning adjusters.
Adjust the brake lining outside diame-
ter to the approximate inside diameter
of the brake drum with Rotunda Tool
HRE-8650 (Fig. 12, Part 2-2).
7.
If all the brake adjusters, brake
drums and linings are functional and
the brake travel is not within specifi-
cations, check the pedal linkage for
missing or worn bushings, or loose at-
tachments. Bleed the brakes and cen-
tralize the differential valve.
POWER BRAKE
FUNCTIONAL TEST
1.
Check the hydraulic brake sys-
tem for leaks or insufficient fluid.
2.
With the transmission in neutral,
stop the engine and apply the parking
brake. Depress the brake pedal several
times to exhaust all vacuum in the
system.
3.
With the engine shut off and all
vacuum in the system exhausted, dep-
ress the pedal, and hold it in the ap-
plied position. Start the engine If theprocarmanuals.com

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.

POWER BRAKE MASTER
CYLINDER PUSH
ROD
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
rod
length
may
be
verified with
a
push
rod

gauge
and
measured with
the
engine
running
to
apply vacuum
to the

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)

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

side.
Refill the master cylinder reser-
voir after each wheel cylinder is bled
and install the master cylinder cover
and gasket. Be sure the diaphragm
type gasket is properly positioned in
the master cylinder cover. When the
bleeding operation is completed, the
fluid level should be filled to within
1/4 inch of the top of the reservoirs.
7. If the primary (front brake) sys-
tem is to be bled. Repeat steps 2
through 6 at the right front brake cal-
iper or cylinder and ending at the left
front brake caliper or cylinder.
8. On disc brake equipped models
be sure that the front brake pistons
are returned to their normal positions
and that the shoe and lining assem-
blies are properly seated by depressing
the brake pedal several times until
normal pedal travel is established.
9. Centralize the pressure differen-
tial valve. Refer to the Centralizing
the Pressure Differential Valve proce-
dures which follow.
PRESSURE BLEEDING
The Lincoln Continental hydraulic
brake system is to be bled only with
pressure bleeding equipment.
Bleed the longest lines first. The
bleeder tank should contain enough
new Ford Brake Fluid to complete the
bleeding operation. Use Ford Brake
Fluid — Extra Heavy Duty — Part
Number C6AZ-19542-A (ESA-
M6C25-A) or equivalent for all brake
applications. The brake fluid is col-
ored blue for identification purposes.
Do not mix low temperature brake
fluid with the specified brake fluid
during the bleeding operations. Never
re-use brake fluid that has been
drained from the hydraulic system.
The tank should be charged with ap-
proximately 10 to 30 pounds of air
pressure. Never exceed 50 pounds
pressure.
1.
Clean all dirt from the master
cylinder reservoir cover.
2.
Remove the master cylinder res-
ervoir cover and rubber gasket, and
fill the master cylinder reservoir with
the specified brake fluid. Install the
pressure bleeder adapter tool to the
master cylinder, and attach the bleed-
er tank hose to the fittng on the
adapter.
Master cylinder pressure bleeder
adapter tools can be obtained from
the various manufacturers of pressure
bleeding equipment. Follow the in-
structions of the manufacturer when
installing the adapter.
3.
If the master cylinder is
equipped with a bleed screw, loosen
the bleed screw and bleed the master
cylinder until the fluid is free of air
bubbles; then, tighten the bleed screw.
Do not use the secondary piston stop
screw, located on the bottom of the
master cylinder, to bleed the master
cylinder.
4.
If the rear wheel cylinders, the
secondary brake system, are to be
bled, position a 3/8 inch box wrench
(Fig. 9) on the bleeder fitting on the
right rear brake wheel cylinder. At-
tach a bleeder tube to the bleeder fit-
ting. The end of the tube should fit
snugly around the bleeder fitting.
5. Open the valve on the bleeder
tank to admit pressurized brake fluid
to the master cylinder reservoir.
6. Submerge the free end of the
tube in a container partially filled with
clean brake fluid, and loosen the
bleeder fitting.
7.
When air bubbles cease to ap-
pear in the fluid at the submerged end
of the bleeder tube, close the bleeder
fitting and remove the tube.
8. Repeat steps 3 through 7 at the
left rear wheel cylinder.
9. If the vehicle is equipped with
disc brakes, repeat steps 4 through 7,
starting at the right front disc caliper
and ending at the left front disc cali-
per.
On Lincoln Continental models the
front wheel and tire assemblies must
be removed to gain access to the
bleeder fittings on the calipers. Also
on Lincoln Continental models the
metering valve release rod must be
pulled outward and held a minimum
of 1/16 inch (Fig. 10) while bleeding
the primary brake system.
10.
If the vehicle contains drum-
type front brakes and the primary
(front) brake system is to be bled, re-
peat steps 4 through 7, starting at the
right front wheel cylinder ending at
the left front wheel cylinder.
11.
When the bleeding operation is
completed, close the bleeder tank
valve and remove the tank hose from
the adapter fitting.
12.
On disc brake equipped ve-
hicles,
be sure that the front brake
pistons are returned to their normal
positions and that the shoe and lining
assemblies are properly seated by dep-
ressing the brake pedal several times
until normal pedal travel is esta-
blished.
13.
Remove the Pressure Bleeder
Adapter Tool. Fill the master cylinder
reservoirs to within 1/4 inch of the
top.
Install the master cylinder cover
and gasket. Be sure the Diaphragm
type gasket is properly positioned in
the master cylinder cover.
14.
Centralize the pressure differen-
tial valve as follows.

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

per splash shield or the bleeder screw
fitting.
4.
Front wheel bearing end play is
critical and must be within specifica-
tions.
5.
Be sure the vehicle is centered on
the hoist before servicing any front
end components, to avoid bending or
damaging the rotor splash shield on
full right or left wheel turns.
6. The proportioning valve should
not be disassembled or adjustments
attempted on it.
7.
Riding of the brake pedal (com-
mon on left foot applications) should
be avoided during vehicle operation.
8. The wheel and tire must be re-
moved ' separately from the brake
rotor, unlike drum brakes where the
wheel, tire and drum are removed as a
unit.
9. On floating caliper type disc
brakes whenever the caliper is re-
moved the caliper locating pins should
be inspected for wear or damage.
10.
On floating caliper type disc
brakes, the caliper assembly must be
removed from the spindle prior to re-
moval of the shoe and lining assem-
blies.
11.
On floating caliper type disc
brakes the calipers must not be inter-
changed from one side to the other.
When the caliper is installed on its
proper anchor plate and spindle, the
bleeder screw will point to the rear of
the vehicle (Fig. 22). If a caliper is in-
stalled on the wrong side of the vehi-
cle,
it is not possible to bleed the sys-
tem properly.
12.
Do not attempt to clean or re-
store oil or grease soaked brake lin-
ings.
When contaminated linings are
found, brake linings must be replaced
in complete axle sets.
DRUM BRAKES
1.
Remove the wheel from the
drum, and remove the drum as out-
lined in Part 2-2, Section 2.
2.
Brush all dust from the backing
plates and interior of the brake
drums.
3.
Inspect the brake shoes for ex-
cessive lining wear or shoe damage. If
the lining is worn within 1/32 inch of
the rivet heads or if the shoes are
damaged, they must be replaced. Re-
place any lining that had been con-
taminated with oil, grease or brake
fluid. Replace lining in axle sets. Prior
to replacement of lining, the drum di-
ameter should be checked to deter-
mine if oversize linings must be in-
stalled.
4.
Check the condition of brake
shoes,
retracting springs, hold-down
springs, and drum for signs of over-
heating. If the shoes have a slight blue
coloring, indicating overheating, re-
placement of the retracting and hold-.
down springs is strongly recommended.
Overheated springs lose their pull and
could cause the new lining i:o wear
prematurely, if they are not replaced.
5. If the vehicle has 30,000 or more
miles of operation on the brake linings
or signs of overheating are present
when relining brakes, the wheel cylin-
ders should be disassembled and in-
spected for wear and entrance of dirt
into the cylinder. The cylinder cups
should be replaced, thus avoiding fu-
ture problems.
6. Inspect all other brake parts and
replace any that are worn or dam-
aged.
7.
Inspect the brake drum and, if
necessary, refinish. Refer to Part 2-2,
Section 4 for refinishing.
BRAKE BOOSTER
Check the booster operation as
noted in Part 2-1, Section 1, Power
Brake Functional Test. If the brake
booster is damaged or defective, re-
place it with a new booster. The brake
booster is serviced only as an assem-
