WARNING
After servicing the brakes, always
check them for function. If the stroke of
the lever is excessive, or if you detect
that the effectiveness of the brakes is
reduced in any way, have your vehicle
serviced by your Local
APRILIA
Dealer.
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 vehicle in traffic immedi-
ately after servicing the brakes.
Always apply the brake pedal or lever
several times before riding your vehicle.
Then, try your vehicle in a parking lot or
other safe area with little traffic to ensure
that the brakes are working properly.
Failure to observe this warning can lead
to a serious accident with subsequent se-
rious injury or death.
