Adjustment
BRAKES
Brake
lining
and drum
wear,
and cable stretch cause
the
brakes to go
out of adjustment,
increasing lever
and
pedal play and decreasing braking effectiveness. Front
brake adjustment to
compensate
for this actually con·
sists
of following
three
adjustments: cam lever angle,
brake shoe synchronization, and brake lever. Rear
brake
adjustment to compensate
for this
actually consists of
three
successive adjustments:
brake
pedal
position,
cam
lever
angle,
and
brake
pedal
travel.
If brake drag
is
detected during brake
adjustment,
disassemble the brake
(Pg.
201
or
202), and inspect
for
wear
or
damage (Pg. 209).
Also,
if
the brake
lever
or
pedal does not
return
to its
rest
position
quickly upon
release,
inspect the brake
for wear
or
damge. If
the
brake
has a
soft, or
"spongy
feeling",
make
sure
the
brake panel is properly
synchron ized
or
centered.
See
"Brake Shoe Synchronization" (Pg. 202)
or
the "NOTE"
in
the
front
wheel
installation procedure
(Pg.
199).
On the outside of the
front brake
panel
there is a
brake
lining
wear
indicator. Whenever
the
indicator
has
gone past USABLE
RANGE, the
brake
shoes must be
immediately
replaced and the other brake
parts ex-
amined.
Adjustment
alone cannot
compensate for the
wear
of a
brake worn past USABLE
RANGE.

D. USABLE RANGE
•When
the
brake
is fu
ll
y
applied,
the
primary brake cam
lever
should
come
to an 80-90° angle with the thread·
ed extension of
the
brake
cable,
at
the
same
t ime as
which
the
secondary
brake cam lever
should be
parallel
with
the primary brake
cam lever.
•If they
do not,
r
emove
the cam
levers and
then
re-
mou'nt
them
at
new
positions
on the
shafts to achieve
the
proper
angle, or loosen the locknut and
turn the
connecting rod
to make
the two
cam levers
parallel.
I
WARNING •
Since a cam
lever
angle greater than 90°
..._ _ _ _ . . _ reduces braking effectiveness, this adjust·
ment should not be neglected. When remounting the
A. Primary Brake Cam Lever
B. Secondary Brake Cam Lever
cam, be sure that the position of the indicator on
the
serrated shaft is not altered. See Pg. 201 for detailed
information
on the position of the wear indicator
when
the cam lever
is
not on
the
shaft.
A change in cam lever
angle
is
caused by wear of
internal
brake parts.
Whenever
the
cam lever
angle is adjusted, also
check
for drag and
proper lever operation, taking particular note of the
brake
lining wear
indicator position. In case of doubt as
to braking effectiveness, disassemble and inspect all
internal brake
parts. Worn part~ could cause the brake
to lock
or
fail.
•Rotate
the
whee
l
to
check tor brake
drag.
•Operate
the brake
lever a few times
to

it

to
its

posit.ion immediately
upon

•Ad just

lever.
Brake Shoe Synchronization
After
the
front
wheel
is
removed,
or after
the
brake
was
disassembled,
synchronize
the brake
shoes.
•Raise
the
front
wheel
off
the
ground
by
some
means.
•Loosen
the
locknuL
and turn the
con necting
rod
one
turn clockwise.
Th is
procedure backs
off the secondary
brake shoe
so
that it
will
not operate
when the
primary
shoe
contacts
the
inside
surface
of
the drum
