Some possibilities:
  • dirty rim (clean with rubbing alcohol).
  • pads toe'd in the wrong direction (adjust pads).
  • slight wobble in the rim (true wheel).
  • brake not centered (loosen mounting bolt, have someone squeeze the lever tightly while you tighten the mounting bolt).
  • rim not well aligned at the joint (smooth with emery cloth or 400 to 1000 grit sand paper - remove wheel from bicycle, and tire from rim, protect freehub/freewheel and wheel bearings, sand, clean with rubbing alcohol, put back together)
  • brake pads glazed (remove, sand braking surface, rinse with water, dry, reinstall).
