Cam Lever Angle
•When the brake
is
fu
lly applied,
the
brake cam lever
shou
ld
come
to
an 80-90° angle with
the brake
rod.
A. 80-90°
•If
it does
not,
remove the
cam lever,
and then
remount
it
at
a new position
on
the
shaft for
the
proper
angle.
[ WARN
ING
I
Since a cam lever angle greater than
90°
.., _____ .. _
reduces
braking effectiveness, this adjust-
ment should
not
be neglected. When remounting the
cam,
be sure that the position of the indicator on
the
serrated shaft
is not
altered. See Pg. 203 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 pedal 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 parts could caui.e the brake
to lock or
fai
l.
•Rotate the
rear
wheel to check
for
brake drag.
•Operate the
pedal
a few
times
to
see
that it returns
to
its
rest
position immediately
upon
release.
•Ad just
the brake
pedal
travel.
Brake Pedal Travel
•Check to
see that the
brake pedal
has
20
-30 mm
of
travel
from
the
rest
position
to the
fu
lly
applied
posi·
tion when
the
brake
pedal
is pushed
down lightly by
hand.
A.
Adjusting Nut
B. 20-30
mm
•If it does
not, turn
the adjusting
nut
on the
end
of the
brake
rod so that the brake
pedal
has the proper
travel.
•Rotate the rear wheel
to
check
for brake drag.
•Operate
the pedal a
few
timse to see
that it returns
to
its
rest
position
immediately upon
release.
•Check
the rear
brake
light
switch
operation.
WHEEL BALANCE (Wire-spoke Wheel)
To improve
stability
and decrease vibration at h igh
speed,
the front and rear wheels must
be
kept
balanced.
Check and
balance
the
wheels when required, or
when a tire
is
replaced
with a new
one.
•Remove
the wheel (Pg.
198 or 202).
•Check
the all the spokes are tightened evenly and the
rim runout
is
within
the
service
limit (Pg.
207).
•Suspend
the wheel
so that it can be
spun freely.
•Spin
the wheel
lightly, and
mark
the
spoke
at the
top
when the
wheel
stops.
•Repeat th is
procedure
several
times.
If
the
wheel
stops
ot
its own accord in various positions, it
is
well
bal·
anced.
•However, if
the wheel
always stops in one
position,
attach a
balance weight
loosely
to
the
marked spoke.
A. Balance Weight
•Rotate the
wheel
\4
turn,
and see whether
or not
the
wheel
stays
in this position.
If it
does, the
correct
balance weight
is
being
used.
A. Use heavier size
B. Use lighter size
•If the
wheel
rotates
and
the weight goes
up, replace
the
weight with
the next heavier size. If the
wheel
rotates and
the
weight
goes down, replace the
weight
with
the next
lighter
size.
Repeat these steps
until
the wheel remains at
rest
after
being
rotated
1,4
turn
.
•Rotate
the
wheel another
1,4
turn and then another
l4
turn to see
if
the
wheel
is
correctly
balanced.
