Repeat
as many
times
as
may be necessary until
the
fluid
emerging
from
the
tube Into
the
jar is
qUite
free of bubbles.
When
this
condition
Is
satisfied,
operate
the
control
fully and
securely
tighten
the
bleed
nipple.
Only
after
this has been done should
the
lever
or
pedal
be
released. Check the
fluid
level
in
th~
reservoir,
as
detailed earlier, and replace
the
dlap~
hragm and
the
filler cap.
Special
Note:
It
Is
important
that
the bleed nipple and
all
ripe

• BLEEDING
THE
SYSTEM (SPECIAL
NOTE,
REAR BRAKE)
Before proceeding with the operation, withdraw
the
rear
wheel spindle
by
an
amount sufficient
to
release
the
torque
arm which carries
the
tallper unit.
The
unit, stili attached
to
the arm must be lowered
to
the
ground,
'~hen
the
bleed nipple
will
be
at
the
highest point
of
the
fluid
contal led
In
the
caliper.
This
is
essential,
in
order
to
avoid
trapping
air
bubbles,
which
would
reduce
the
efficiency
of
the
brake.
During
the
operation
of
bleeding this
brake,
a
metal
packing
piece
of
the
same
thickness
as
the
disc
MUST
be
inserted
between
the
brake
pads.

MASTER
CYLINDER/CONTROL
LEVER
BODY
The
control lever assembly and
the
triple switch
housing
are
Independent units, clamped
together
on
the
handlebar
by
four screws,
facing
forward,
and
after
thes'e are removed,
the
units
can
be
separated.
The
stop-light switch
is
retained
in
the
control lever
body
by
a small screw, which must
be
removed,
when
the
switch and
Its
two leads can be withdrawn,
but
still attached
to
the triple switch assembly.
The
leads
are
soldered
In
position. and should not be
disconnected unless the switch
Is
to
be
renewed.
Adjustment
of
the
stop-light switch
Is
by
means
of
the
small screw carried
In
a block of Insulating
material within
the
lever. The setting of
the
screw
should
be such
that
when the lever
Is
fully
released,
the
stop-light remains extinguished, but
as
soon
as
the
lever
Is
gripped
and
has
moved
by
a small
amount
only
the
stop-light
is
illuminated.

The cylinder unit of
the
front brake
Is
screwed Into
the
control body, and
Is
retained
by
a small
socket
screw. When
the
latter
Is
slackened.
the
master
cylinder and control lever body
can
be
seperated
and attention given
to
either part
as
reqUired. A
service kit of parts
Is
available for repairs
of
a
comparatively. minor nature,
but
If
these
are
not
sufficient
to
effect a repair,
It
will
be
necessary
to
replace the whole unit. When re-assembllng,
first fit
the
stop-light switch and securely tighten Its
locking screw. When
the
master cylinder
Is
replaced, or a new one fined.
It
should be
screwed
Into
the
control lever body,
uneil
ail
play
In
the
lever
Is
only Just taken up, and the socket
screw
tightened. Finally replace
the
four clamping
screws.
It will then
be
necessary
to
fill
the
reservoir with
hydraulic fluid, and bleed
the
system,
as
described
In
Section Fl.
Similar Instructions apply
to
the
rear brake unit.
