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.

DISASSEMBLY

1.
Remove the links and the rubber

boots from the ends of the brake cyl-

inder. Remove the pistons, cups, and

return spring from the cylinder bore

(Fig. 12).

2.
Remove the bleeder screw from

the cylinder.

INSPECTION

1.
Wash all parts in clean brake

fluid. Dry with compressed air.

2.
Replace scored pistons. Always

replace the rubber cups and dust

boots.
3.
Inspect the cylinder bore for

score marks or rust. If either condi-

tion is present the cylinder bore must

be honed. However, the cylinder

should not be honed more than 0.003

inch beyond its original diameter.

4.
Check the bleeder hole to be sure

that it is open.

ASSEMBLY

1.
Apply a light coating of heavy-

duty brake fluip! to all internal parts.

2.
Thread the bleeder screw into the

cylinder and tighten securely.

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
