these joints are disassembled, repack bearings

and lubricate reservoir at end of trunnions with

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.
Using a suitable socket or rod, press trunnion down

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

trunnion (fig. 104). .

NOTE:
Installation of seal is critical to proper

sealing - use specified tool during installation to

prevent seal distortion and to assure proper

seating of seal on trunnion.

6. Partially install one bearing cup into yoke. Place

trunnion in yoke and into bearing cup. Install other

bearing cup and press both bearing cups into yoke

(fig. 105) being careful to keep trunnion aligned in

bearing cups.

7. Press bearing cups far enough to install lock rings,

and install lock rings.

Installation

1.
Inspect yoke seal in the transmission and replace, if

necessary, as described in the transmission section.

2.
Insert propeller shaft front yoke into transmission.

NOTE:
On Corvette models, install front yoke

into transmission then position propeller shaft

between yoke and companion flange; install "U"

bolts to front yoke.

3.
Align propeller shaft with companion flange, using

reference marks established in "Removal" pro-

cedure, connect the rear universal joint by installing

"U"
bolt clamps over bearing trunnions - torque

nuts to specifications.

Removal

1.
Raise vehicle sufficiently to permit access to propel-

ler shaft and mark relationship of rear yoke to

companion flange.

2.
Remove trunnion bearing retaining strap attaching

screws from both bearings (fig. 106).

3.
Lower rear of propeller shaft, being careful not to

dislodge bearing caps from trunnion, and tape bear-

ing caps to trunnion.

4.
Withdraw propeller shaft front yoke from transmis-

.sion by moving shaft rearward, passing it under the

axle housing. Watch for oil leakage from transmis-

sion output shaft housing.

Repairs

NOTE:
Because of the elastic properties of the

nylon retainers, the trunnions must be pressed

from the yokes. Pressing the trunnions from the

yokes will shear the retainers which renders

the bearing caps unsuitable for reuse. A service

Jdt, which employs a snap ring to retain the

trunnion, must be used when reassembling the

propeller shaft (fig. 107).

1.
Remove trunnion at differential end of propeller shaft

shaft using the following procedure:

a. Support splined yoke on a press bed and the rear

of the propeller shaft on a stand so that shaft is

horizontal. Be sure that weight is evenly dis-

tributed on each side of the splined yoke and that

the fixed yoke half of the "U" joint is free to

move downward.

b.
Using a piece of pipe or similar tool, with an

inside diameter slightly larger than 1 1/8", press

bearing from yoke (fig. 108).

c. Apply force on yoke around bearing until nylon

retainer breaks. Continue to apply force until the

downward movement of the yoke forces the bear-

ing as far as possible from the yoke (fig. 109).

d. Complete removal of bearing by tapping around

circumference of exposed portion with a small

hammer (fig. 110).

e. Rotate propeller shaft so that opposite bearing

GENERAL DESCRIPTION

All 1967 models are equipped with a new split brake

system as a safety feature. If a wheel cylinder or brake

line should fail at either the front end or rear end of

the vehicle, the operator can still bring the vehicle to

a controlled stop. The system is designed with separate

hydraulic systems for the front and rear brake using

a dual master cylinder (fig. 1). The design of the master

cylinder is similar to that used on the 1966 Corvette

in that it has two entirely separate reservoirs and outlets

in a common body casting. The front reservoir and outlet

is connected to the front wheel brakes, and the rear

reservoir and outlet is connected to the rear wheel

brakes. Two pistons within the master cylinder receive

mechanical pressure from the brake pedal push rod and

transmit it through the brake lines as hydraulic pressure

to the wheel cylinders. The filler cap is accessible from

inside the engine compartment.

A new brake pipe distribution and switch assembly

is mounted below the main cylinder. The front and rear

hydraulic brake lines are routed from the main cylinder,

through the brake pipe distribution and switch assembly,

to the front and rear brakes as shown in Figure 2. The

switch is wired electrically to the brake alarm indicator

light on the instrument panel. In the event of fluid loss

in either the front or rear brake system the indicator

on the instrument panel will illuminate red. (The indi-
cator will also' be illuminated when the parking brake is

applied.)

On Camaro models equipped with air conditioning, the

rear brake hydraulic line is routed through a pressure

regulator valve mounted on the left frame side rail

(fig. 3). The valve controls the hydraulic pressure to

the rear brakes resulting in the correct pressure balance

between the front and rear hydraulic systems.

The self-adjusting brakes (fig. 4), used on both front

and rear of all models, are the Duo-Servo single anchor

type which utilize the momentum of the vehicle to assist

in the brake application. The self-energizing or
self-

actuating force is applied to both brake shoes at each

wheel in both forward and reverse motion. The brake

shoe linings are bonded to the shoes.

Wheel cylinders are the double piston type permitting

even distribution of pressure to each brake shoe. To

keep out dust and moisture, both ejads of each wheel

cylinder are sealed with a rubber booC The wheel

cylinders have no adjustments.

The Chevrolet, Chevelle, and Camaro parking brakes

have a foot operated ratchet type pedal mounted to the

left of the steering column. A cable assembly connects

the pedal to an intermediate cable by means of an equal-

izer, where the adjustment for the parking brake is

incorporated. The intermediate cable attaches to the

CHEVROLET CHASSIS SERVICE MANUAL

BRAKES 5-2

DELCO MORAINE MAIN CYLINDER

BENDIX MAIN CYLINDER

Fig.
I—Main
Cylinder

two rear cables which operate the rear service brake.

The Chevy II has a single-stroke, ratchet-type parking

brake release lever, located to the right of the steering

column. The lever is connected to the rear wheel brake

assemblies through a two-piece cable and equalizer

assembly. A dash mounted idler lever multiplies force

applied at the parking brake lever and transmits it to

the equalizer by means of the front cable. The one-piece

rear cable passes through the equalizer and is connected
at each end to an actuating lever within the rear brake

assembly.

The Corvette is equipped with a ratchet-type parking

brake lever located behind the console. The parking

brake cable runs forward from the lever to a pulley

assembly mounted on a frame crossmember, then back

to an equalizer near the rear frame crossmember. A

single piece rear cable passes through the equalizer

and back to the rear service brakes.

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.

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

7. Repeat Steps 2 through 7 on the remaining wheel

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
