MAJOR REPAIR OPERATIONS

BRAKE DRUM REFINISHING

Minor scores on a brake drum can

be removed with sandpaper. A drum

that is excessively scored or shows a

total indicator runout of over 0.007

inch should be turned down. Remove

only enough stock to eliminate the

scores and true up the drum. The refi-

nished diameter must not exceed 0.060

inch oversize.

Check the inside diameter of the

brake drum with a brake drum mi-

crometer (Tool FRE-14^1).

If the drum diameter is less than

0.030 inch oversize after refinishing^

standard lining may be installed. If

the drum diameter is 0.030—0.060

inch oversize after refinishing, oversize

lining must be installed.

After a drum is turned down, wipe

the refinished surface with a cloth

soaked in clean denatured alcohol. If

one drum is turned down, the opposite

drum on the same axle should also be

cut down to the same size.

ROTOR REFINISHING

Rotunda Disc Brake Attachment,

FRE-2249-2, is the only recommended

tool to refinish the disc brake rotors.

The step-by-step resurfacing procedure

provided with the tool must be ad-

hered to.

The finished braking surfaces of the

rotor must be flat and parallel within

0.0007 inch; lateral runout must not

exceed 0.003 inch total indicator read-

ing, and the surface finish of the brak-

ing surfaces are to be 80/15 micro

inches. The minimum limiting dimen-

sions (Figs. 11 and 12, Part 2-1) from

the inboard bearing cup to the out-

board rotor face and from the inboard

bearing cup to the inboard rotor face

must be observed when removing ma-

terial from the rotor braking surfaces.

On all models except Lincoln Con-

tinental, the limiting dimensions are to

be measured with a ball and gage bar

(Rotunda Kit FRE-70160).

BRAKE SHOE RELINING

Brake linings that are worn to with-

in 1/32 inch of the rivet head or are

less than 0.030 inch thick (bonded lin-

ing) or have been contaminated with

brake fluid, grease or oil must be re-

placed. Failure to replace worn linings

will result in a scored drum. When it
is necessary to replace linings, they

must also be replaced on the wheel on

the opposite side of the vehicle.

Inspect brake shoes for distortion,

cracks, or looseness. If this condition

exists,
the shoe must be discarded. Do

not attempt to repair a defective brake

shoe.

1.
Wash the brake shoes thoroughly

in a clean solvent. Remove all burrs

or rough spots from the shoes.

2.
Check the inside diameter of the

brake drum with a brake drum mi-

crometer (tool FRE-1431). If the di-

ameter is less than 0.030 inches over-

size,
standard lining may be installed.

If the diameter is 0.030—0.060 inches

oversize, oversize lining should be in-

stalled.

3.
Position the new lining on the

shoe.
Starting in the center, insert and

secure the rivets, working alternately

towards each end. Replacement lin-

ings are ground and no further grind-

ing is required.

4.
Check the clearance between the

shoe and lining. The lining must seat

tightly against the shoe with not more

than 0.008 inch clearance between any

two rivets.

DISC BRAKE CALIPER

ALL MODELS EXCEPT

LINCOLN CONTINENTAL

Disassembly

1.
Remove the caliper assembly

from the vehicle as outlined in Section

2.

2.
Remove the caliper locating pins

from the caliper assembly and lift the

anchor plate from the caliper.

3.
Slide the two outer shoe retain-

ing clips off the retaining pins (Fig.

43).

4.
Remove the two retaining pins,

then remove the outer brake shoe

from the caliper.

5.
Slide the inner brake shoe out-

ward until it is free of the hold-down

springs, then remove the brake shoe.

6. Apply air pressure to the fluid

port in the caliper with a rubber

tipped nozzle (Tool 7000-DD) as

shown in Fig. 44 to remove the piston.

Place a cloth over the piston before

applying air pressure to prevent dam-

age to the piston. If the piston is

seized and cannot be forced from the

caliper, tap lightly around the piston

while applying air pressure. Care

should be taken because the piston

can develop considerable force due to

pressure build-up.

7.
Remove the dust boot from the

caliper assembly.

8. Remove the rubber piston seal

from the cylinder and discard it.

Cleaning and Inspection

Clean all metal parts with isopropyl

alcohol or a suitable solvent. Use

clean, dry, compressed air to clean out

and dry the grooves and passage ways.

Be sure that the caliper bore and com-

ponent parts are completely free of

any foreign material.

Check the cylinder bore and piston

for damage or excessive wear. Replace

the piston if it is pitted, scored, or the

chrome plating is worn off.

Assembly

1.
Apply a film of clean brake fluid

to the new caliper piston seal and in-

stall it in the cylinder bore. Be sure

the seal does not become twisted and

that it is seated fully in the groove.

2.
Install a new dust boot by setting

the flange squarely in the outer groove

of the caliper bore.

3.
Coat the piston with the speci-

fied fluid and install the piston in the

cylinder bore. Spread the dust boot

over the piston as it is installed. Seat

the dust boot in the piston groove.

4.
Position the inner brake shoe so

that the ears of the shoe rests on the

top of the anchor plate bosses and be-

neath the hold-down springs.

5.
Install new caliper locating pin

insulators in the anchor plate.

6. Position the caliper on the an-

chor plate.

7.
Apply water or isopropyl alcohol

to the caliper locating pins and install

them loosely in the anchor plate. Be

sure the guide pins are free of oil,

grease or dirt.

8. Install the caliper on the spindle

as outlined under Disc Brake Caliper

Assembly.

LINCOLN CONTINENTAL

Disassembly

Do not remove the bridge bolts that

hold the two halves of the caliper to-

gether. The two caliper housings are

shown separated in Fig. 46 for illus-

tration purposes only.
1.
Remove the caliper assembly

from the car as outlined in Section 2.

2.
Remove the two attaching bolts

and the caliper splash shield (Fig. 46).

3.
Remove the two shoe and lining

assemblies.

4.
Remove the flexible brake hose

from the caliper.

5.
Remove the external transfer

tube.

6. Remove the four dust boots from

the caliper housings and piston

grooves.

7.
Clamp the caliper in a vise and

secure it by the mounting flanges on

the inboard housing (Fig. 45).

8. Remove the four pistons from

the cylinder bores with the special tool

shown in Fig. 45. To prevent cocking

with consequent damage to the piston

or bore, rotate the piston with the tool

while pulling it outward at the same

time.
Be careful to avoid scratching or

damaging the outside diameter surface

or dust boot retaining groove of the

piston. Such damage causes poor seal-

ing.

If a piston is so completely seized in

the cylinder bore that it can not be re-

moved with the special tool, the cali-

per housing must be replaced, by posi-

tioning two screwdrivers in the piston

dust boot retaining groove and prying

outward. To prevent cocking, tap the

end of the piston lightly around the

circumference with a hammer, while

the prying force is being applied. Be

careful to avoid damaging the dust

boot retainer in the caliper housing

(Fig. 46). If this method of removal is

used, the pistons must be replaced.

If the caliper dust boot retainer or

retaining groove is damaged or

scratched, pry the retainer out of the

caliper housing with screwdrivers.
