OPERATIONS
REAR
BRAKE
DRUM
REFINISHING
Minor
scores on a
brake
drum can
be
removed with
a
fine
emery
cloth.
A
drum
that
is
excessively
scored
or
shows a
total
indicator
runout
or
over
0.007
inch
should
be
turned
down.
Remove
only
enough
stock
to
eliminate
the
scores
and true
up
the
drum.
The
refinished
diameter
must
not
exceed
0.060 inch
oversize
(11.150
inches).
If
the
drum
diameter
is
less than
0.030
inch
oversize
(11.120
inches)
after
refinishing,
standard
lining
may
be
installed. If
the
drum
diameter
is
11.120-11.150
inches,
oversize
linings
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
op
posite drum
on the
same
axle
should
also
be cut
down
to the
same size.

RELINING
Brake
linings
that are
worn
to
within
1/32
inch of
the
rivet or
have
been saturated with
grease or

should
be replaced.
Failure to
replace
worn
linings
will

a
scored
drum. When it
is
necessary
to replace
linings,
they
must
also be
replaced on
the
wheel on the
opposite side
of the
car.
Inspect brake shoes for
distortion,
cracks,
or looseness. If
this condition
exists,
the
shoe should be
discarded.

repair a defective
brake shoe.

brake
shoes
thorough
ly
in a
clean
solvent.
Remove all
burrs
or
rough
spots
from
the shoes.
2. Check
the
inside
diameter
of
the
brake
drum.
If the
diameter
is less
that
11.120
inches,
standard
linings
may
be
installed. If the
diameter
is
11.120-11.150
inches,
oversize
lining
should be
installed.
3. Position
the
new
lining
on
the
shoe.
Starting

secure
the
rivets,

towards each
end.

more
than
0.005 inch
