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.
