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, check the brake system, see p. 47
(DISC BRAKES) it may be necessary to bleed the
system, or there may be some other problem with the
brake system. Never ride your vehicle in traffic immediately
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 serious injury or death.
Check the tightening torques, centering and balancing
of the wheel, see p. 55 (INSPECTING THE
WHEELS). These are critical safety operations, and
failure to observe this warning could lead to an upset
with subsequent serious injury or death.
