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.
