Adjustments Rear Brake MAINTENANCE AND LUBRICATION The rear brake is a hydraulic disc brake. The rear brake system is self-adjusting and requires no maintenance other than periodic checks of the pads for wear. Pads should be changed when worn to 3/64″ (.1 cm), which is about the thickness of a U.S. dime. Inspect the brake disc spline and pad wear surface for excessive wear. 3/64″ (.1 cm) Auxiliary Brake Your vehicle'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 depressing the foot pedal on the inside of the right footrest. The hydraulic auxiliary brake system will not need adjustment. NOTE: Since this is a rear brake only, it will not be as effective as the all-wheel single lever system. 105
