Brake System

DESCRIPTION
Disc brakes are available as option-
al equipment for the front wheels on
Ford, Mercury, Meteor, Fairlane,
Montego, Falcon, Mustang and Cou-
gar models and are standard on Thun-
derbird, Continental Mark III, and
Lincoln Continental models. The
dual-master cylinder equipped hydrau-
lic brake system employs single an-
chor, internal expanding and
self-
adjusting drum brake assemblies on
the rear wheels of vehicles with disc
brakes, and on the front and rear
wheels of all others.
A vacuum booster is used with the
power disc brake system.
DUAL MASTER CYLINDER
BRAKE SYSTEM
The dual-master cylinder brake sys-
tem has been incorporated in all mod-
els to provide increased safety. The
system consists of a dual-master cylin-
der (Fig. 1), pressure differential valve
assembly and a switch (Fig. 2). The
switch on the differential valve acti-
vates a dual-brake warning light, lo-
cated on the instrument panel.
DISC BRAKE
The disc brake consists of a venti-
lated rotor and caliper assembly. The
caliper used on all models except Lin-
coln Continental is a single piston
floating caliper (Fig. 3). The caliper
used on Lincoln Continental models is
a four piston fixed caliper (Fig. 4).
A proportioning valve in the rear
hydraulic circuit provides balanced
braking action between front and rear
brakes.
On all models except Lincoln a
pressure impulse valve located at the
primary inlet of the pressure differen-
tial valve prevents brake fluid surge
back to the master cylinder reservoir.
On Lincoln Continental models a
metering valve, in the hydraulic line
between the differential valve and the
front wheel disc brakes, prevents the
front brakes from applying until ap-
proximately 125 psi is obtained in the
system (Fig. 21). This delaying action
is required to prevent the front brakes
from performing all the braking ac-
tion on low speed stops and thereby
increasing the rate of lining wear.
FLOATING CALIPER—
ALL MODELS EXCEPT
LINCOLN CONTINENTAL
The caliper asseml.y is made up of
a floating caliper housing assembly
and an anchor plate. The anchor plate
is bolted to .the wheel spindle arm by
two bolts. The floating caliper is at-
tached to the anchor plate by steel
stabilizers on Ford, Mercury, Meteor,
Thunderbird and Continental Mark
III models and by one stabilizer on
Fairlane, Montego, Falcon, Mustang
and Cougar models. The floating cali-
per slides on two locating pins which
also attach to the stabilizers. The
floating caliper contains the single cyl-
inder and piston assembly. The cylin-
der bore contains a piston with a
molded rubber dust boot to seal the
cylinder bore from contamination
(Fig. 5). A square section rubber pis-
ton seal is positioned in a groove in
the cylinder bore and is used to pro-
vide sealing between the cylinder and
piston (Fig. 7).
The outer brake shoe and lining as-
sembly is longer than the inner assem-
bly, and the shoe and lining

brake adjustment then connect the
parking brake cable to the parking
brake lever (Fig. 8).
4.
Install the shoe guide (anchor
pin) plate on the anchor pin when so
equipped.
5.
Place the cable eye over the an-
chor pin with the crimped side toward
the backing plate.
6. Install the primary shoe to an-
chor spring (Fig. 15).

FIG. 75—Retracting Spring
Installation
7.
Install the cable guide on the
secondary shoe web with the flanged
hole fitted into the hole in the second-
ary shoe web. Thread the cable
around the cable guide groove (Fig.
8).
It
is
imperative that
the
cable
be
positioned
in
this groove
and not be-
tween
the
guide
and the
shoe
web.
8.
Install the secondary shoe to an-
chor spring with the tool shown in
Fig. 15.
Be certain that
the
cable
eye is not
cocked
or
binding
on the
anchor
pin
when installed.
All
parts should
be
flat
on
the
anchor
pin.
Remove
the
brake
cylinder clamp.
9. Apply high-temperature grease
(MIC-100-A) to the threads and the
socket end of the adjusting screw.
Turn the adjusting screw into the ad-
justing pivot nut to the limit of the
threads and then back off 1/2 turn.
Interchanging
the
brake shoe
ad-
justing screw assemblies from
one
side
of
the
vehicle
to the
other would cause
the brake shoes
to
retract rather than
expand each time
the
automatic
ad-
justing mechanism operated.
To pre-
vent installation on the wrong side of
the vehicle, the socket end of the ad-
justing screw is stamped with an R or
L (Fig. 16). The adjusting pivot nuts
can be distinguished by the number of
grooves machined around the body of
the nut. Two grooves on the nut indi-
cate a right thread; one groove indi-
cates a left thread.
10.
Place the adjusting socket on
the screw and install this assembly be-
tween the shoe ends with the adjusting
screw toothed wheel nearest the sec-
ondary shoe.
11.
Hook the cable hook into the
hole in the adjusting lever. The adjust-
ing levers are stamped with an R or L
to indicate their installation on right
or left brake assembly (Fig. 16).
12.
Position the hooked end of the
ADJUSTING LEVER

and
Lever Identification
adjuster spring completely into the
large hole in the primary shoe web.
The last coil of the spring should be at
the edge of the hole. Connect the loop
end of the spring to the adjuster lever
hole.
13.
Pull the adjuster lever, cable
and automatic adjuster spring down
and toward the rear to engage the
pivot hook in the large hole in the sec-
ondary shoe web (Fig. 8).
14.
After installation, check the ac-
tion of the adjuster by pulling the sec-
tion of the cable between the cable
guide and the anchor pin toward the
secondary shoe web far enough to lift
the lever past a tooth on the adjusting
screw wheel. The lever should snap
into position behind the next tooth,
and release of the cable should cause
the adjuster spring to return the lever
to its original position. This return ac-
tion of the lever will turn the adjusting
screw.one tooth.
If pulling the cable does not pro-
duce the action described, or if the
lever action is sluggish instead of posi-
tive and sharp, check the position of
the lever on the adjusting screw
toothed wheel. With the brake in a
vertical position (anchor at the top),
the lever should contact the adjusting
wheel 3/16 inch (plus or minus 1/32
inch) above the centerline of the
screw. If the contact point is below
this centerline, the lever will not lock
on the teeth in the adjusting screw
wheel, and the screw will not be turned
as the lever is actuated by the cable.
To determine the cause of this con-
dition:
a. Check the cable end fittings. The
cable should completely fill or extend
slightly beyond the crimped section of
the fittings. If it does not meet this
specification, possible damage is indi-
cated and the cable assembly should
be replaced.
b.
Check the cable length. On
Ford, Mercury, Meteor, Thunderbird,
Continental Mark III, and Lincoln
Continental models, the cable should
measure 11 1/8 inches (plus or minus
1/64 inch) from the end of the cable
anchor to the end of the cable hook.
On Fairlane, Montego, Falcon,
Mustang, and Cougar models the
cable should measure 8 13/32 inches
on 9 inch brakes or 9 3/4 inches on
10 inch brakes from the end of the
cable anchor to the end of the cable
hook.
c. Check the cable guide for dam-
age.
The cable groove should be paral-
lel to the shoe web, and the body of
the guide should lie flat against the
web.
Replace the guide if it shows
damage.
d. Check the pivot hook on the
lever. The hook surfaces should be
square with the body of the lever for
proper pivoting. Replace the lever if
the hook shows damage.
e. See that the adjusting; screw
socket is properly seated in the notch
in the shoe web.
