Auxiliary Brake Systems
Your ATV’s auxiliary brake system is intended to be used as a backup for the
main brake system. Should the main system fail, the rear brake can be
activated by stepping the foot pedal on the side of the right floorboard. The
hydraulic brake system will not require adjustment.
NOTE: Auxiliary brake system will be as effective as the rear wheels system in
2WD mode. It will cause braking at both front and rear wheels in the 4WD
mode.

screw out (counterclockwise) will lower RPM.
