high-melting point wheel bearing lubricant and

replace the dust seals.

1.
Remove bearing lock rings from trunnion yoke.

2.
Support trunnion yoke on a piece of 1-1/4" I.D. pipe

on an arbor bed.

NOTE:
Due to length of the propeller shaft it

may be more convenient to use a bench vise,

for removal and installation, instead of an arbor

press.
In this case, proceed with disassembly

and assembly procedure as with an arbor press.

3.

far enough to drive bearing cup from yoke (fig. 103).

4.
Remove dust seals from trunnion, clean and inspect

bearing rollers and trunnion. Relubricate bearings

with a lithium base chassis lubricant.

NOTE:
In addition to packing the bearings,

make sure that the lubricant reservoir at the

end of each trunnion is completely filled with

lubricant. In filling these reservoirs, pack lu-

bricant into the hole so as to fill from the

bottom. This will prevent air pockets and ensure

an adequate supply of lubricant.

5. Place new dust seals on trunnions - cavity of seal

toward end of trunnion - then position Tool J-21548
over end of trunnion and into cavity portion of seal.

Press seal onto trunnion until tool bottoms against

MAINTENANCE AND ADJUSTMENTS

In any service operation it is extremely important

that absolute cleanliness be observed. Any foreign matter

in the hydraulic system will tend to clog the lines, ruin

the rubber cups of the main and wheel cylinders and

cause inefficient operation or even failure of the braking

system. Dirt or grease on a brake lining may cause

that brake to grab first on brake application and fade

out on heavy brake application.

The split system consists basically of two separate

brake systems. When a failure is encountered on either,

the other is adequate to stop the vehicle. If one system

is not functioning, it is normal for the brake pedal lash

and pedal effort to substantially increase. This occurs

because of the design of the master cylinder which

incorporates ah actuating piston for each system. When

the rear system loses fluid and takes in air, its piston

will bottom against the front piston. When the front

system loses fluid and takes in air, its piston will

bottom on the end of the main cylinders body. The loss

of fluid in one of the systems causes an uneven hydraulic

pressure balance between the front and rear systems.

The brake pipe distribution and switch assembly, near

the main cylinder, detects the loss of pressure and il-

luminates the brake alarm indicator light on the instru-

ment panel. The pressure loss is felt at the brake pedal

by an apparent lack of brakes for most of the brake

travel and then, when failed chamber is bottomed, the

pedal will harden.

HYDRAULIC BRAKE FLUID

Use GM Hydraulic Brake Fluid, Supreme No. 11 or

equivalent when servicing brakes. This brake fluid is

satisfactory for any climate and has all the qualities

necessary for proper operation, such as a high boiling

point to prevent vapor lock and the ability to remain

fluid at low temperatures.
In the event that improper fluid has entered the system,

it will be necessary to service the system as follows:

1.
Drain the entire system.

2.
Thoroughly flush the system with clean alcohol,

188
proof,
or a hydraulic system cleaning fluid

such as "Declene".

3.
Replace all rubber parts of the system, including

brake hoses.

4.
Refill the system.

5. Bleed the system.

BLEEDING HYDRAULIC SYSTEM

The hydraulic brake system must be bled whenever

any line has been disconnected or air has in some way

entered the system. A ''spongy" pedal feeling when the

brakes are applied may indicate presence of air in the

system. The system must be absolutely free of air at

all times. Bleeding should be done on the longest line

first; the proper sequence to follow is left rear, right

rear, right front, and left front (fig. 5). Bleeding of

brake system may be performed by one of two methods—

either pressure or manual.

PRESSURE
BLEEDING

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

cylinder cover and rubber diaphragm.

2.
Reduce fluid level in main cylinder until reservoirs

are approximately half full.

NOTE:
Make sure brake fluid in bleeder equip-

ment is at operating level and that the. equipment

is capable of exerting 30 to 50 lbs. hydraulic

pressure on the brake system.

3.
Install brake bleeder adapter J-22489 (fig. 6) on

main cylinder. Connect hose from bleeder equipment

to bleeder adapter and open release valve on bleeder

equipment.

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

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

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

8. Fill the main cylinder to the levels shown in

Figure 8.

9. Install main cylinder diaphragm and cover.

PUSH ROD TO MAIN CYLINDER CLEARANCE

The brake pedal has a definite stop which is permanent

and not adjustable. This stop consists of a rubber

bumper at the release end of pedal travel. Before

adjusting push rod to main cylinder clearance, make

sure pedal returns to the fully released position freely

and that the pedal retracting spring has hot lost its

tension, then proceed as follows:

1.
Loosen check nut on push rod.

2.
Turn push rod as required to provide correct ad-

justment. Movement of pedal pad before push rod

contacts main cylinder pistons must be 1/16" to

1/4" (fig. 9).

3.
Tighten check nut against clevis, and recheck

movement.

HYDRAULIC BRAKE LINES

Hydraulic Brake Hose

The flexible hoses which carry the hydraulic pressure

from the steel lines to the wheel cylinders are carefully

designed and constructed to withstand all conditions of

stress and twist which they encounter during normal

vehicle usage.
The hoses require no service other than periodic

inspection for damage from road hazards or other like

sources. Should damage occur and replacement become

necessary, the following procedure is to be followed.

Removal

1.
Separate hose from steel line by turning double

flare connector out of hose fitting.

2.
Remove "U" shaped retainer from hose fitting and

withdraw hose from support bracket.

3.
Turn hose fitting out of wheel cylinder inlet.

Replacement

1.
Install new copper gasket on cylinder end of hose

(male end).

2.
Moisten threads with brake fluid and install hose in

wheel cylinder inlet.

3.
With weight of car on wheels and suspension in

normal position (front wheels straight ahead) pass

female end of hose through support bracket, allowing

hose to seek its own position. Insert hex of hose

fitting into the 12 point hole in support bracket

in position which induces least twist to hose (figk 10).

NOTE:
Do not twist hose unduly during ^

operation as its natural curvature is absolutely

necessary to maintain proper hose-tot

suspension clearance through full movement o£

the suspension and steering parts.

4.
Install "U" shaped retainer to secure hose in sup-

port bracket.

5. Inspect by removing weight completely from wheel,

turn wheels from lock to lock while observing hose

position. Be sure that hose does not tough other

parts at any time during suspension or wheel travel.

If contact does occur, remove hose retainer and

rotate the female hose end in the support bracket

one or two points in appropriate direction, replace

retainer, and re-inspect.

6. Place steel tube connector in hose fitting and tighten

securely.

7. Bleed all brakes as outlined in this section.

8. Do not tighten male end (wheel cylinder end) once

the other end is fixed. If necessary to tighten male

1 end, disconnect hose at opposite end, then reconnect

following above procedure.

Hydraulic Brake Tubing

Hydraulic brake tubing is a double layer annealed

steel terne plate tubing which resists corrosion and has

the physical strength to stand up under the high pr.es-
Fig.
11—Hydraulic Brake Tube Double Flaring Tool

sures which are developed when applying the brakes. In

making up hydraulic brake pipes, it is important that

the proper flaring tool be used to flare the ends of the

tubing for the compression couplings. Unless the tubing

is properly flared, the connections will leak and the

brakes will become ineffective.

CAUTION: When necessary to replace brake

tubing, always use special steel tubing which

is designed to withstand high pressure and re-

sist corrosion. Ordinary copper tubing is not

satisfactory and should not be used.

This safety steel tubing must be double-lap flared at

the ends in order to produce a strong leak-proof joint.

The brake tube flaring. Tool J-8051 (fig. 11) is used to

form the double-lap flare.

Figure 12 shows two pieces of tubing, one with single-

lap flare "A" and the other with double-lap flare "B".

It will be noted that the single-lap flare in "A" split

the tubing while the one shown in "B" is well-formed and

unbroken due to the reinforcement of the double wall.

The following procedure should be followed in making

up hydraulic brake pipes.

Double Lap Flaring

1.
Clamp the tubing in the proper size die blocks with

the flat ends of the blocks toward the end of the

tubing to be cut off. Cut the end of the tubing flush

and square. Using a mill file, dress tubing and

square ends.

2.
Remove the tubing from the die block and deburr

the inside and outside edges.

3.
Install compression couplings on tubing and dip end

of tubing to be flared in hydraulic fluid. This lubri-

cation results in better formation of the flare.

4.
Place on-half of the die blocks in the tool body with

the counterbored ends toward the ram guide. Now

lay the tubing in the block with approximately 1/2"

protruding beyond the end.

Fit the other half of the block into the tool body,

close the latch plate and tighten the nuts "finger

tight".

5. Select the correct size upset flare punch. One end

of this punch is counterbored or hollowed out to

gauge the amount of tubing necessary to form a

double lap flare. Slip the punch into the tool body

with the gauge end toward the die blocks. Install the

ram; then tap lightly until the punch meets the die

, blocks and they are forced securely against the

stop plate (fig. 13).

6. Using the supplied wrench, draw the latch plate

nut down tight to prevent the tube from slipping.

Tightening the nuts alternately (beginning with the

nut at the closed hole in the plate) will prevent

distortion of the plate. Remove the punch and the

ram. Now reverse the punch and put it back into the

tool body. Install the ram and tap it lightly until

the face of the upset flare punch contacts the face

of the die blocks (fig. 14). This completes the

first operation. Remove the ram and the punch.

7. To complete the flare, insert the pointed finish

flare punch and the ram into the tool body. Tap

the ram until a good seat is formed (fig. 15).

NOTE:
The seat should be inspected at inter-

vals during the finishing operation to avoid

over-seating.
