WARNING
After servicing the brakes, always
check them for function. If the stroke of
the lever or pedal is excessive, or if you
detect that the effectiveness of the
brakes is reduced in any way, have your
motorcycle serviced by your Local
Delear. It may be necessary to
have your dealer bleed the system, or
there may be some other problem with
the brake system.
Never ride your motorcycle in traffic im-
mediately after servicing the brakes. Al-
ways apply the brake pedal or lever sev-
eral times before riding your motorcycle.
Then, try your motorcycle in a parking
lot or other safe area with little traffic to
ensure that the brakes are working prop-
erly. Failure to observe this warning can
lead to a serious accident with subse-
quent serious injury or death.
