I have a Kazuma Dingo 150. Took it riding and when I got back I was riding around the yard and heard a clunking. I looked and on the rear axle the rotor is loose and the caliper is loose. Looks like I need to tighten the big nut on the axle against the rotor. as for the caliper it is definitely missing a nut or something and not sure how it went together. Anyone have a picture of a rear brake assembly for the model or a Kazuma so i can see how its suppose to go together? Any help is appreciated thanks!
