is there a good way to even out a lumpy rim joint? it doesnt seam (sic, pun, sorry) to affect braking but it makes this really annoying thumping sound. how do i get rid of it?

New problem?Kerry

Did the rims come this way, or is this a developing problem? Is the braking surface actually uneven, or is it contaminated with brake pad material? If the rims came this way and are not contaminated, you're not going to have much luck. You can obviously sand them down with a sanding block, but you may overly thin the side wall and make them more uneven if you're not careful. If this problem is getting worse (and is not contamination), then you're in the market for new rims. First, clean the rims with solvent and a ScotchBrite pad. If that doesn't help, you may be stuck with it.

I'd try to get a new rim warranteed if this happened. I've had old rims, especially rear touring wheels, develop this problem after lots of miles. Eventually, I was unable to true them at the seam and junked 'em.
