and
retaining
clip.
2.
Apply
a
light
coating
of
high-
temperature
grease
at
the
points
where
the
brake
shoes
contact the
car
rier
plate.
3.
Position
the
brake
shoes
on
the
carrier
plate
and
secure
the
assembly
with
the
hold-down
springs.
Install
the
parking
brake
link
and
spring.
Connect
the
parking
brake
cable
to
the
parking
brake
lever
(Fig. 4).
4.
Install
the
anti-rattle
clip
and
the
anchor
pin
plate on
the
anchor
pin.
5.
Place
the
cable
eye over
the an
chor
pin
with the
crimped
side
toward
the
carrier
plate.
6.
Install
the
cable
guide on
the
secondary
shoe
web with
the
flanged
hole
properly
fitted
into the
hole in
the
secondary
shoe web.
Thread the
cable
around
the
cable guide
groove
(Fig.
4).
It
is imperative
that
the
cable be
positioned in this
groove and not
between the guide and
the shoe web.
7.
Install the
secondary
shoe
to
anchor
spring
(Fig.
13)

Spring
Installation
8.
Install the
primary
shoe
to
an
chor
spring
with
the tool
shown
in
Fig.
4.
Be
certain
that
the
cable
eye is
not
cocked
or
binding
on the
anchor
pin
when
installed.
All parts
should
be
flat
on
the
anchor
pin.
9.
Apply
high-temperature
grease
to
the
threads
and
the
socket
end
of
the
adjusting
screw.
Turn
the
adjust
ing
screw into
the
adjusting
pivot
nut
to
the
limit
of
the
threads
and
then
back
off
1/2
turn.
Interchanging
the
brake
shoe
adjust
ing
screw
assemblies
from
one
side
of
the car to
the
other
would
cause
the
brake shoes
to
retract
rather
than
ex
pand each
time
the
automatic
adjust
ing
mechanism
operated.
To
prevent
installation
on
the
wrong
side
of the
car,
the socket
end
of
the
adjusting
screw
is
stamped
with an
R
or
L
(Fig.
14). The
adjusting
pivot
nuts
can
be
distinguished
by
the
number
of
grooves
machined
around
the
body
of
the
nut. Two
grooves
on the
nut
in
dicate a
right
thread,
one
groove
in
dicates a
left
thread.

10. Place the
adjusting
socket
on
the
screw
and
install this
assembly
between the
shoe
ends
with the adjust
ing
screw
toothed
wheel nearest the
secondary
shoe.
11.
Hook the cable
hook
into
the
hole
in the
adjusting
lever.
The adjust
ing
levers
are stamped
with an
R
or
L
to
indicate their
installation on a right
or left brake
assembly
(Fig.
14).
12. Position the hooked
end of the
adjuster
spring
completely
into
the
large
hole in the
primary
shoe web.
The last
coil
of the
spring
should
be
at
the
edge
of
the
hole.
Connect
the
loop
end
of the
spring
to
the adjuster lever
hole.
13. Pull the
adjuster
lever,
cable
and
automatic
adjuster
spring
down
and toward the rear to engage
the
pivot hook in
the
large hole
in
the sec
ondary
shoe web (Fig.
4).
14.
After
installation,
check the ac
tion of the adjuster
by pulling
the sec
tion of the cable between the cable
guide and the
adjusting
lever
toward
the
secondary
shoe web far enough
to
lift
the lever past a tooth on the adjust
ing
screw wheel.
The lever
should
snap
into
position
behind the next
tooth,
and
release of the cable
should
cause the
adjuster
spring
to
return the
lever
to its
original
position. This
return
action of the
lever will
turn the
adjusting
screw one tooth.
If
pulling
the
cable
does not pro
duce
the
action
described,
or if
the
lever
action
is
sluggish
instead
of
positive and
sharp,
check the position
of
the
lever
on
the
adjusting
screw
toothed
wheel.
With
the
brake
in a
vertical
position
(anchor at
the
top),
the
lever
should
contact
the
adjusting
wheel
3/16
inch
(plus
or
minus
1/32
inch)
above
the
centerline
of the
screw.
If
the
contact
point
is
below
this
centerline,
the
lever
will not
lock
on the
teeth in
the
adjusting
screw
wheel,
and
the
screw will not
be
turned
as
the
lever is
actuated
by
the
cable.
To
determine
the
cause of this
condition:
a.
Check
the
cable end
fittings.
The
cable
should
completely
fill or
extend
slightly
beyond the
crimped
section
of
the
fittings.
If
it
does not
meet this
specification,
possible
damage is in
dicated
and
the cable
assembly
should
be
replaced.
b. Check the
cable
length.
The
cable
should
measure
11 1/8
inches
(plus
or minus
1/64
inch)
from
the
end
of the cable
anchor to
the end
of
the
cable hook.
c. Check
the cable
guide for dam
age. The cable
groove should be
par
allel
to
the shoe
web,
and the
body
of
the guide
should lie flat
against the
web. Replace the
guide
if
it shows
da
mage.
d.
Check
the
pivot
hook on the
lever.
The
hook
surfaces
should be
square with the
body
of the lever for
proper pivoting. Replace the
lever if
the hook shows
damage.
e.
See that the
adjusting
screw
sock
et is
properly
seated
in the
notch
in
the shoe
web.
