5—Correct Bleeding Sequence

4.
Install brake bleeder wrench, Tool J-21472 on bleed-

er valve at wheel cylinder and install one end of

bleeder hose on bleeder valve (fig. 7).

5.
Pour a sufficient amount of brake fluid into a trans-

parent container to insure that end of bleeder hose

will remain submerged during bleeding. Place the

loose end of bleeder hose into the container. Be

sure the hose end is submerged in the fluid.

6. Open wheel cylinder bleeder valve by turning Tool

J-21472 counterclockwise approximately 1/3 of a

turn and observe flow of fluid at end of bleeder

hose.

7.
Close bleeder valve tightly as soon as bubbles stop

and brake fluid flows in a solid stream from the

bleeder hose.

8. Remove brake bleeder wrench and bleeder hose

from wheel cylinder bleeder valve.

9. Repeat Steps 4 through 8 on the remaining wheel

Cylinders in the correct bleeding sequence (fig. 5).

10.
Disconnect bleeder equipment from brake bleeder

adapter cover J-22489.

NOJE: The main cylinder on certain passenger

car models is tilted upward. When removing

the bleeder adapter on these models, place a

clean dry cloth behind and below the cylinder

to absorb any fluid spillage as the cover is

removed. v

MANUAL BLEEDING

1.
Clean all dirt from top of main cylinder and remove

cylinder cover and rubber diaphragm.

2.
Fill main cylinder reservoirs.

3.
Install brake bleeder wrench, Tool J-21472 on bleed-

er valve at wheel cylinder and install one end of

bleeder hose on bleeder valve (fig. 7).

4.
Pour a sufficient amount of brake fluid into a trans-

parent container to insure that end of bleeder hose

will remain submerged during bleeding. Place the

loose end of bleeder hose into the container. Be

sure the hose end is submerged in the fluid.

NOTE: Carefully monitor fluid level at main

cylinder during manual bleeding operations. Do

not bleed enough fluid at one time to drain the

reservoir completely. Replenish the reservoirs

with fluid while bleeding to insure a sufficient

amount of fluid is in the main cylinder at all

times.
To insure that outside air is not sucked

back into the hydraulic system, the bleeder

valve should be closed before the brake pedal

reaches the floor.

5.
Open wheel cylinder bleeder valve by turning Tool

J-21472 counterclockwise approximately 1/3 of a

turn. Slowly depress brake pedal. Just before brake

pedal reaches the end of its travel, close bleeder

valve and allow brake pedal to return slowly to the

fully released position. Repeat this procedure until

lifted on the rim to force the top tire bead

against the top rim flange. The weight of the

tire will seat the bottom bead.

Repair

When a tire loses all or most of its air pressure,

particularly when driving at high legal speeds on today1 s

super-highways, recommended procedure is to remove it

from the wheel for complete inspection to be sure no

tire damage has occurred. Punctured tires should be

removed from the wheel and permanently repaired from

the inside.

Externally applied plug type repairs should be con-?

sidered temporary and the tire should be permanently

repaired as soon as possible.

Hot Patch Method

It is essential to thoroughly clean and remove all

foreign matter from the hole left by the puncturing-object

without enlarging the injury and then follow the manu-

facturer's instructions for vulcanizing the patch.

Rubber Plug Methods

There are several types of rubber plugs--some are

inserted from the inside of the tire; others are inserted

from the outside of the tire without demounting the tire

from the rim.

When using the plug method be sure to clean and

lubricate the hole with repair cement before inserting

the plug. Your tire supplier has available complete kits

containing materials, tools and detailed instructions for

making repairs with plugs. Follow instructions in the kit

you use.

Cold Patch Method

(Self Vulcanizing Type)

In this method it is essential to thoroughly clean and

remove all foreign matter from the hole left by the

puncturing object without enlarging the injury; also on

the inside of the tire, buff an area large enough for the

patch. Follow the manufacturer1 s instructions for appli-

cation of the special cement and self-vulcanizing cold

patch.
Pressure Gun Method

Several types of pressure guns are available. Consult

your tire supplier for materials and instructions.

Tire Installation Safety Precautions

When tires are mounted on dirty or corroded rims, or

when they are not properly centered on rims, the tire

bead may "bind" on the rim, and refuse to seat. Allowing

pressure to continue to build up within the assembly in

an attempt to seat the tire bead is a DANGEROUS PRAC-

TICE which can result in a broken tire bead, and serious

injury to the serviceman.

1.
Make sure that rim flanges and bead ledge (espe-

cially hump and radius) areas are smooth and clean.

Remove any oxidized rubber, dried soap solution,

rust, heavy paint, etc. with a wire brush, or, in ex-

treme cases, a file.

2.
Lubricate tire beads, rim flanges, and bead ledge

areas with a liberal amount of thin vegetable oil

soap solution, or approved rubber lubricant,

3.
Insure that air pressure build-up during the bead

seating process is not allowed to exceed 40 pounds

pressure. If beads have not seated by the time pres-

sure reaches 40 pounds, assembly should be deflated,

re-positioned on rim, re-lubricated and re-inflated.

4.
Make sure valve core is inserted in valve stem

prior to inflating.

5.
Use an extension gauge with clip on chuck so air

pressure build-up can be closely watched and so

that you can stand well back from the assembly

during the bead seating process.

Valve Assembly

Replace

NOTE: Always use new valve assembly when

replacing.

1.
Cut or drive old valve assembly out of rim.

2.
Clean valve hole and surrounding area on inside of

flange with steel wool.
