VEHICLE WARRANTY NUMBER
The vehicle warranty number is the first line of numbers and
letters appearing on the Warranty Plates (Fig. 1). The Warranty
Plate is riveted to the left front door lock face panel. The first
number indicates the model year. The letter following the model
year number indicates the manufacturing assembly plant. The next
two numbers designate the Body Serial Code followed by a letter
expressing the Engine Code. The group of six digits remaining on
the first line indicate the Consecutive Unit Number.
VEHICLE DATA
The vehicle data appears on the second or lower line on the
Warranty Plate. The first two numbers and a letter identify the
Body Style. A letter or a number appears next indicating the
Exterior Paint Color followed by a number-letter combination
designating the Interior Trim. To the right of this code appears the
Date Code indicating the date the car was manufactured. A two-
digit number next designates the district in which the car was
ordered and may appear in conjunction with a Domestic Special
Order or Foreign Special Order number when applicable. The final
two spaces indicate the Rear Axle Ratio (numbers for regular axles,
letters for locking-types) and the Transmission type (numbers for
manual,
letters for automatic).
OFFICIAL VEHICLE IDENTIFICATION NUMBER
The official Vehicle Identification Number (VIN) for title and
registration purposes is stamped on an aluminum tab that is riveted
to the instrument panel close to the windshield on the driver's side
of the car and is visible from outside (Fig. 2).
MODEL YEAR CODE
The number 9 designates 1969.

o'clock position on the steering wheel
rim.
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.

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

blies are not interchangable (Fig. 23).
The outboard shoe and lining is fixed
to the floating caliper and is retained
by two pins and spring clips. The shoe
and lining assembly consists of fric-
tion material bonded to a metal plate
called the shoe. It is replaced as a
unit.
FIXED CALIPER
LINCOLN CONTINENTAL
The caliper assembly is bolted di-
rectly to the wheel spindle arm by two
bolts.
The caliper assembly consists of
two caliper housings bolted together
with each half containing two cylinder
bores of 1.938 inch diameter. Each
cylinder bore contains a piston with
an attached molded rubber dust boot
to seal the cylinder bore from contam-
ination (Fig. 6). Square-section rubberprocarmanuals.com

piston seals are positioned in grooves
in the cylinder bores and are used to
provide hydraulic sealing between the
cylinders and pistons (Fig. 7).
The cylinders are connected hydrau-
lically by means of internal passages
in the caliper housings and an external
transfer tube between the two halves
of the caliper assembly. One bleeder
screw and fluid inlet fitting is provided
on each caliper assembly.
The shoe and lining assemblies are
located in between parallel machined
abutments within the caliper, and are
supported radially by tabs on the
o'uter ends of the shoe assemblies (Fig.
46).
The shoes slide axially in the cali-
per abutments by means of the tabs
which ride on machined ledges (bridg-
es) when hydraulic pressure is applied
to the piston (Fig. 6). A shoe and lin-
ing assembly consists of friction mate-
rial riveted to a metal plate called the
shoe.
It is replaced as a unit. Clips are
attached to the top of the caliper to
retain the shoe and lining assemblies.
The caliper assembly is mounted on
the front wheel spindle to the rear of
the wheel vertical centerline.
ROTOR
The cast iron disc is of the ventilat-
ed rotor-type incorporating forty fins
and is attached to, and rotates with
the wheel hub. A splash shield bolted
to the spindle is used primarily to pre-
vent road contaminants from contact-
ing the inboard rotor and lining sur-
faces.
The wheel provides protection
for the outboard surface of the rotor.
DRUM BRAKE
The drum brake system employs
single anchor, internal expanding ancj
self adjusting brake assemblies.
The self-adjusting brake mechanism
consists of a cable, cable guide, ad-
justing lever, adjusting screw assem-
bly, and adjuster spring (Fig. 8). The
cable is hooked over the anchor pin at
the top and is connected to the lever
at the bottom. The cable is routed
along the webb of the secondary brake
shoe by means of the cable guide. The
adjuster spring is hooked to the pri-
mary brake shoe and to the lever. The
automatic adjuster operates only when
the brakes are applied while the vehi-
cle is moving rearward and only when
the secondary shoe is free to move
toward the drum beyond a predeter-
mined point.

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
