GENERAL DESCRIPTION

.
A
structural network
of
steel forms the backbone
of
the

Corvette body. When combined with
the
fiber-glass
re-

inforced plastic body panels,
the
steel-plastic marriage

results
in a
body with increased torsional rigidity
and

greater beaming strength.
Convertible models continue with two roof styles:
the

folding
top
and the removable hardtop. In operation, both

tops function similar to those
of
previous models. Either

top
is
standard and both
are
optional
as
determined by

the top selected
as
base equipment.

plastic body panels. The general area around the welding

operation should be protected with wet asbestos or any

other like method (several thicknesses of aluminum foil

makes an excellent heat shield if out of the way of direct

flame).

Straightening of steel parts while still in body must be

done with care. When applying hydraulic jacks or like

equipment which operates by exerting force, bear in

mind that the part being used to brace the stationary end

of tool must be able to withstand such usage and that

fiber glass parts, though tougher than steel, will not yield

or "take a set" as with steel parts, so naturally they

cannot be "straightened". If poor alignment exists due

to collision or other physical damage, check steel re-

inforcements in cowl, roof and sill areas (fig. 69) with

care.

Tracing line of damaging force and checking body

carefully for broken bonds and cracks before, during

and after repairs will pay off repeatedly.

Small cracks and faults in bonds and panels will usually

grow larger if left unattended.

REPAIR PANELS

Body repair panels are illustrated in Figures 66

through 70. Those shown are typical of panels which are

available through Chevrolet parts sources. Procedures

which may be used for installing panels are explained in

the following pages.

Figure 71 illustrates various bonds which will be en-

countered during repair procedures. The legend for

Figure 71 cites typical applications for bonds shown.

surrounding the scratch with Lacquer Removing

Solvent.

2.
Featheredge the repair area with No. 220 wet or

dry sandpaper and finish block sand with No. 320

wet or dry paper, Figure 79.

CAUTION: Do not sand too deeply into fiber-

glass mat. Should it be necessary to cut fairly

deep into the glass mat use the repair pro-

cedure suggested for dents and pits in plastic

panels.
3.
Clean up repair area Prep-Sol or its equivalent,

then finish the clean-up with a tack rag.

4.
Protect surrounding panels by masking before per-

forming paint refinishing operations. Use only non-

staining type masking tapes on Corvette plastic body.

5. Refinish panel as described in paint refinishing

portion of this manual.

Dents or Pits in Panels,. Cracks in Glaze Coat

glancing blow, resulting in an indentation or large pit

in the panel. The following procedure is advised for a

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.
