Adjustment of Disc Brake
When the brake is
disassembled, it must
be
ad-
justed and bled completely.
1 .
Check the brake lever
free play
The
lever
free play is specified to be 2~5
mm l0.0787 ~0.1969
in.I at
the
tip of the
lever.
If
the
free play is out of specification, check
and replace if necessary.
2.
Check
the brake
fluid level
Fill the master cylinder oil resevoir up to the
level line.
Caution:
Do not allow the brake fluid to come in
contact
with the painted surfaces,
rubber
part
s
and
in-
struments.
3.
Bleed the
broke lines
In the hydraulic
brakes,
air
trapped
in
the
brake
lines
will
reduce the
braking effect
to
result in dangerous riding.
If
the brake lever
is felt spongy when
it
·
is-
squeezed or if the
brake fluid level lowers
excessively,
bleed the
brake
lines.
To bleed, proceed
as follows:
a.
Fill
the
master
cylinder
oil reservoir
up to
the
level line.
b.
Install
the diaphragm
to
prevent
the
fluid
from
splashing.
c.
Put a
pipe
on the bleeder screw located
to
the
caliper.
Prepare
an oil can.
d. As shown at
right
,
attach
a
rubber of
about
1
5 mm thick to the
end
of the
handle
grip
to decrease the stroke as measured at
the tip of the
handle
lever.
e.
Squeeze
the
brake lever
and
operate it several
times
until
a
resistance is
felt
.
With
the
lever
squeezed,
loosen
the
bleeder
screw
about
1
/
2
turn.
As soon as
the
lever bears
on the
handlebar
pipe, tighten
the
bleeder
screw.
Continue the bleeding operat ion
until
air bubbles are
no
longer noted in the fluid
flowing
out
of the bleeder
hole.
Note:
While bleeding,
add
brake fluid.
