Inspecting the
brake
fluid
level
Insufficient
brake
fluid
may
let
air
enter
the
brake system,
possibly
causing
the
brakes
to
become
ineffective.
Before
riding,
check
that
the
brake
flu-
id is
above
the
minimum
level
and
re-
plenish
when
necessary.
Observe
these
precautions:
1.
When
checking
the
fluid
level,
make
sure the top
of
the
master
cylinder
is
level
by
turning the
handlebars.
Use
only the
designated
quality

Refill
with
the
same
type
of
brake
fluid.
Mixing
fluids
may
result
in
a
harmful
chemical
reaction
and
lead
to
poor brake performance.
Be
careful that
water
does
not en-
ter
the
master
cylinder
when
refill-
ing.
Water
will
significantly
lower
the

may
result
in
vapor
lock.

deteriorate
paint-
ed
surfaces or
plastic parts. Al-
ways
clean
up

immediately.
Have a

check
the
cause
if
the
brake
fluid
level
goes
down.
