After adjusting the brake lever position, make sure
that the pin on the brake lever holder is firmly
inserted in the hole in the adjusting dial.
CAUTION:

that there is no brake drag.
WARNING
A soft or spongy feeling in the brake lever can
indicate the presence of air in the brake system.
Before the vehicle is operated, the air must be
removed by bleeding the brake system. Air in the
brake system will considerably reduce braking
performance and could result in loss of control
and possibly an accident. Therefore, check and, if
necessary, bleed the brake system.
