• I'm trying to put some cantilever brakes back onto a repainted frame and am having a couple of issues:

    1. One of the bolts won't go in more than a few turns before it tightens.

    2. On all of the bolts there is a small gap between the rubber spring covers and the mounts on the frame (where the brakes are supposed to go all the way on but for some reason don't).

    It was all working fine when I unbuilt the bike and I kept all the bits together so I don't think there's anything missing.

    The frame was properly masked-off when it was repainted.

    Any help much appreciated... my girlfriend will be needing her bike back soon for work!

  • Sounds like paint/powder has got into the threads and built up around the lips of the canti studs.

    Threads will need chasing with a tap, and lips gently filing/sanding until the brakes sit flush like before.
