Installation

1.
Wipe roof panel with a Xylol solvent such as 3M

Adhesive cleaner or equivalent, should be used to

remove or smooth but excess old cement. Apply

solvent and allow to soak before rubbing.

2.
Where possible, install new cover at room tempera-

ture (approximately 72 s) to permit easier fitting and

removing of wrinkles from the cover assembly.

3.
Determine center line of roof panel by marking

center points on front of hard top and back window

opening. Fold cover lengthwise. Lay cover on roof

panel. Determine overhang (approximately 1").

4.
Apply nitrile non-staining vinyl trim adhesive (such

as 3M Vinyl Trim Adhesive) to the ropf panel ad-

jacent to center line of fabric roof cover. *

5V Application of nitrile vinyl trim cement should be as

thin as possible. An excessive amount of cement may

result in trapped solvents (blisters) between fabric
cover and roof panel. A mohair roller should be used

for thin adhesive application.

NOTE:
If nitrile non-staining cement is not

available, neoprene type non-staining weather-

strip cement (3M weatherstrip cement or

equivalent) may be used.

6. Apply cement to entire fabric roof cover.

NOTE:
Allow approximately 15 minutes for

7.
cement to dry.

Fold vinyl cover back to contact adhesive on roof

panel. Vinyl cover seam must be parallel to center-

line of vehicle.

8. Repeat above steps for opposite side of
roof.

9. Use suitable spatula or roller to remove wrinkles

and/or bubbles from vinyl cover.

2.
Using an electric wood burning needle or low heat.

soldering gun, scrape off an appropriate amount of

vinyl from scrap piece of material or from hidden

area and immediately apply to scuffed or cut area on

car.

CAUTION: Be certain low heat is maintained to

prevent discoloration of cover.

3.
Carefully blend applied vinyl to fabric roof cover,

utilizing electric needle or soldering gun.

Wrinkles, Blisters and Bubbles

1.
Pierce each wrinkle, blister and bubble on fabric

roof cover with a small needle.

2.
Completely saturate a clean shop towel with water

and wring out.

3.
Apply cloth to wrinkle or blistered area.

4.
Apply a home type laundry iron over shop towel using

back and forth strokes until towel is dry. (If iron

has heat control settings, control should be set to

"wool".)

CAUTION: Do not continue to use iron after

towel has become dry as
excess,
heat may cause

permanent damage to vinyl roof cover.

5.
Remove towel and4nspect area. If slight wrinkles or

blisters are still present, perform the following

steps:

6. Using a syringe and hypodermic needle filled with

clear water, inject sufficient water into wrinkle or

bubble to dampen fabric backing.

7.
Repeat steps 2 through 4.
FOLDING TOP

CARE OF THE FOLDING TOP

To avoid water stains, mildew, or possible shrinkage

of the top material, do not keep the top folded for ex-

tended periods of time if it is damp or water soaked.

Permit top to dry out in a raised position before stowing.

Also avoid pasting advertising stickers, gummed labels

or masking" tape on the plastic back window. In addition

to being difficult to remove, the adhesive on these

stickers may also be injurious to the plastic composition

of the window.

Care of Rear Window

The large plastic rear window in the folding top will

remain in good condition for the life of the top if given

proper care. Due to the texture of the plastic window,

it is susceptible to scratches and abrasions; therefore,

when cleaning the window, follow the steps outlined below.

The folding top adjustments are:

Header (View A, Fig. 101)

Header assembly may be moved fore and aft when the

two clamping screws are loosened. This will correct such

conditions as header latch guide pin alignment with the

holes in the windshield upper frame. Symptoms of mis-

alignment are such conditions as loose top trim when

top is up and locked, and excessive effort required to

engage header locks. Note that it will be necessary to

remove side roof rail weatherstrip to gain access to

header outer clamping screw. Refer to Weatherstrip

portion of this section.

Hinge (View B, Fig. 101)

The hinges may be moved up and down and fore and aft

to the limit of the slotted holes in hinge plate and body.

To gain access to hinge, remove rigid plastic trim as

explained in Interior Trim portion of this section. Re-

positioning hinge will correct conditions such as poor top

fit at upper and rear edge of windows; faulty fore and aft

engagements of rear bow hold-down pins in lock assem-

blies and loose or oversight top rear panel when top is

raised and properly locked in position.

Rear Bow Hold-Down Locks (View C, Fig. 101)

The hold-down pins may be moved to left or right to
center top on body in raised position; thus correcting

poor alignment at windows and difficult entry of pins

in locks.

TOP ASSEMBLY REMOVAL AND INSTALLATION

The entire top assembly (frame with trim attached)

may be removed from vehicle as follows:

1.
Raise top, but do not engage header or rear bow

locks.

2.
Remove rigid plastic trim as outlined in Interior

Trim portion of this section.

3.
Mark installed position of hinge by scribing outline

of hinge plate on lock pillar surface.

4.
Remove two screws retaining each hinge to lock

pillar and remove top assembly from vehicle.

Figure 110 illustrates construction features of the

folding top frame and linkage. Various cross sections in

Figure 110 show the pivoting joints and their assembly.

If an operation is being performed which requires

removal of folding top trim, follow directions in this

section. The entire frame assembly may be removed and

replaced as a unit. Follow instructions for Folding Top

Trim and Rear Window Assembly and Top Assembly—

Removal and Installation.

The pivoting joints should be lubricated with light

machine oil once a year. Apply oil sparingly so as not

to stain top trim.
WEATHERSTRIP

Side Rail Weatherstrip

Figure 111 illustrates installation of side rail weather-

strip which acts to seal window opening. The weather-

strip is held in place by studs which are part of the

weatherstrip assembly, and by neoprene base cement

which is applied between weatherstrip and side rail

surface.

When replacing weatherstrip remove all rust, old

cement and foreign material from the surfaces to be

cemented, to assure successful bonding. Use only good

quality neoprene cement suitable for weatherstrip

application.

Header Weatherstrip

Weatherstrip assembly is retained to the header panel

by a combination of studs, sheet metal screws and special

fasteners as shown in Figure 112, along with neoprene

base weatherstrip cement.

Figure 99 shows' a cross section of weatherstrip taken

through a special fastener. To replace fastener, rotate

ninety degrees to align fastener head with slot. Follow

directions for cementing in the Side Rail Weatherstrip

instructions preceding this write up.

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.

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.

BRAKE DRUMS

Front brake drums are the demountable type; that is,

they can be removed without removing the hub. Rear

brake drums are demountable and may be removed

wihtout removing the axle shaft.

A lanced "knock out" area (fig. 34) is provided in

the web of the brake drum for servicing purposes in

the event retracting of the brake shoes is required in

order to remove the drum.

A small screw driver or hooked wire may be inserted

to disengage the automatic adjuster actuating lever so

the star wheel may be turned.

Removal

1.
Raise vehicle and place on jack stand.
2.
Remove wheel and tire assembly, back off brake

adjustment and remove drum.

Inspection and Reconditioning

Whenever brake drums are removed they should be

thoroughly cleaned and inspected for cracks, scores,

deep grooves, and out-of-round. Any of these conditions

must be corrected since they can impair the efficiency

of brake operation and also can cause premature failure

of other parts.

Smooth up any slight scores by polishing with fine

emery cloth. Heavy or extensive scoring will cause

excessive brake lining wear and it will probably be

necessary to rebore in order to true up the braking

surface.

An out-of-round drum makes accurate brake shoe

adjustment impossible and is likely to cause excessive

wear of other parts of brake mechanism due to its

eccentric action.

A drum that is more than .008" out-of-round on the

diameter is unfit for service and should be rebored.

Out-of^round, as well as taper and wear can be ac-

curately measured with an inside micrometer fitted

with proper extension rods.

If drum is to be rebored for use with standard size

brake facings which are worn very little, only enough

metal should be removed to obtain a true smooth braking

surface.

If drum has to be rebored more than .020" over the

standard diameter, it should be rebored to .060" diameter

oversize and the brake facing should be replaced with

.030"
oversize facings.

A brake drum must not be rebored more than .060"

over the maximum standard diameter, since removal

of more metal will effect, dissipation of heat and may

cause distortion of drum. Chevrolet brake facing is

not furnished larger than .030" oversize and this will

not work efficiently in drums bored more than .060"

oversize.

Brake drums may be refinished either by turning or

grinding. Best brake performance is obtained by turning

drums with a very fine feed. To insure maximum lining

life,
the refinished braking surface must be smooth and

free from chatter or tool marks, and run-out must not

exceed .005" total indicator reading.

Cleaning

New brake drums in parts stock are given a light.

coating of rust proofing oil to prevent the formation of

rust on the critical braking surfaces during the time

that the drums are in storage.

This rust proofing oil must be carefully removed

before the drum is placed in service to prevent any

of this oil from getting on the brake shoe facings, which

might cause an extreme brake grab condition.

It is recommended that a suitable volatile, non-toxic,

greaseless type solvent be used to clean the oil from the

braking surface of the new brake drums before they are

•placed in service to insure the cleanest possible surface.

Gasoline or kerosene should not be used as there is

danger that a portion of the diluated oil substance may

be left on the braking surface that may later cause

difficulty.

Installation

1.
Make brake adjustment as outlined in this section.
