I just polished my wheels and was putting them back on tonight...when I ran into a problem. The rear wheel mounts up fine, but when I tighten the axle bolt down...the bracket holding the caliper on, starts rubbing the rotor!! Anybody know what would be the cause...I have triple checked the chain tensionor...every thing should be lining up, but its not...PLEASE HELP!!!

 

are you sure you put the spacers in their proper sides of the rear wheel?

Check a parts fiche, or manual and see if you mixed the sides up... that might be the culprit.
