w8After adjusting the brake lever
free play, check the free play
and make sure that the brake
is working properly.
8A soft or spongy feeling in the
brake lever can indicate the
presence of air in the
hydraulic system. If there is air
in the hydraulic system, have
a Yamaha dealer bleed the
system before operating the
motorcycle. Air in the
hydraulic system will diminish
the braking performance,
which may result in loss of
control and an accident.
