NOTE: The brake adjustment is inside of the left and right brake. Do not adjust the brake by means of the
brake cables as this will cause mis-operation of the brakes. If you hear a single “clunking” noise
while braking it may be due to mis-adjustment of the brake cables or linkage. Refer to
Replace
Brake Linkages/Cables for information regarding proper adjustment of the cables and linkages.
