The old rubbing rim on brakes pad problem?-try this..
Feel and listen to your wheel as well as look at it to figure out where to tighten or loosen your spokes to make it true again.
Usually a spoke(s) directly opposite or very near the spot where your rim rubs is the guilty culprit. strum, (as in guitar), the other spokes on to get an idea how they sound, a loose spoke will often have lower note than the others, or the spoke(s) opposite the "rub" will feel looser. If the problem is just from loosened spokes the rim will have a slight high spot, as a spoke loosens the rim goes away from the hub as well as to the opposite side. If you have more than one bad spot, work on the worst first, then on the worst on THE OTHER SIDE, and so on, back and forth a little at a time until you're done.
Look out for flat spots, usually from bashing into something, sometimes the spokes on both sides will be loose. Whenever you true our inspect your wheels check to make sure your brake pads will not touch your tire anywhere when engaged or open. To check for flat or high spots, sight along your brake pad to the edge of the rim from the side. There are some shops that have a tool to pull out flat spots or you can make your own to push them out.
If the spokes spokes have "tightened up" opposite the rub and the spokes on the near side are loose, you have a " sprung wheel", most of the time a new rim is in order. Sometimes a simultaneous push with a knee and pull with the hands in the right spots will help, at least for a while, maybe longer with luck.
