inch.
However,
if
the
car
was
stopped
by
a
brake
application
just
prior
to
checking
the
clearance,
the
brakes
may
drag
slightly.
4.
To
check
rotor
runout,
first
eliminate
the
wheel
bearing
end
play
by
tightening
the
adjusting
nut.
After
tightening
the
nut
check
to see
that
the
rotor
can still
be
rotated.
5.
Clamp
a dial
indicator
to the
caliper
housing
so
that the
stylus con
tacts
the
rotor
at a
point
approximate
ly
1
inch
from
the outer
edge.
Rotate
the
rotor
and take
an
indicator
read
ing. If
the
reading
exceeds 0.002
inch
total
indicator
runout,
replace the
rotor.
Do not
attempt
to
refinish a
rotor
that
indicates
runout
in
excess
of
specification.
When
the
runout
check
is
finished
be
sure
to
adjust the
bearings as
outlined in
Group
3,
in
order
to
prevent
bearing
failure.
6. Check
the rotor
for
scoring.
Minor
scores
can
be removed
with a
fine
emery
cloth. If
the rotor
is exces
sively
scored replace it.
7.
Visually
check the caliper.
If
it
is
cracked or if
excess
leakage
is
evident,
it
should
be replaced.
Slight leakage
or
seized pistons
indicate
removal
and
disassembly.
8. If
upon
disassembly
the
caliper
is found
to
be
distorted
or
damaged,
or if
the
cylinder
bores are
scored
or
excessively
worn,
replace
the as
sembly.
The two
halves
of
the caliper
as
sembly
should never
be separated.
Damage or
failure of
one requires re
placement
of both
as a unit.
REAR
BRAKES
1. Remove
the wheel from
the
drum,
and remove the drum
as
out
lined in
Part
2-2,
Section 2. Wash
all
the parts
except the brake
shoes
in
a
cleaning
fluid
and
dry
with com
pressed air.
2. Brush all
dust from
the carrier
plate and interior of the
brake
drum.
3.
Inspect the brake
shoes
for ex
cessive
lining
wear or shoe
damage.
If
the
lining
is worn
to
within
1/32
inch
of the rivet
heads
or if
the shoes are
damaged,
they
must be replaced.
Rep
lace
any
lining
that has been
oil
satu
rated. Replace the
lining
in
axle sets.
Prior
to replacement
of the
lining,
the
drum
diameter
should
be
checked to
determine if
oversize
linings must
be
installed.
4. Check
the
condition of the
brake
shoes,
retracting
springs,
and
drum
for signs
of
overheating. If
the shoes
have a slight
blue
coloring,
or
if
the
springs
show a
change
in
free
length,
indicating
overheating,
replacement
of
the
retracting
and hold
down springs
is
necessary.
Overheated
springs lose
their
pull and
could
cause
the
new
lin
ing
to
wear
prematurely
if
they
are
not
replaced.
5. If
the car has
30,000
or more
miles
of
operation
on the brake
lin
ings,
or signs
of
overheating
are pres
ent
when
relining
brakes,
the
wheel
cylinders
should be
disassembled
and
inspected
for wear and dirt
in the
cylinder.
The
cylinder cups and
other
parts
contained
in the
overhaul
kit
should be
replaced,
thus
avoiding
future
problems.
6. Inspect
all other brake parts and
replace
any
that
are
worn
or da
maged.
7. Inspect the brake
drums
and,
if
necessary,
refinish. Refer
to
Part
2-2,
Section
4
for
refinishing.
