I'm restoring a post-war bike with cantilever brakes. One of the canti bosses was broken and
has been cut down, as you can see in the attached picture. Also, I think the bosses are not
straight/parallel. I took a few pictures of this, but it's not easy to see in pictures.
Can anyone advise on what to do? So far, my options seem to be:
1) Drill/tap a hole in what's left of the boss and use a bolt to fix on the canti - this seems to be
how the 'Problem Solvers' canti repair kit works. This doesn't solve the problem of the
bosses not quite being straight, though.
2) Have new canti bosses brazed on. The only problem is that the diameter of the existing
stud is about 1mm bigger than a normal canti stud - could I use a shim of some sort to fix this?
It seems Bob Jackson charges about £15 for brazing a canti boss on, so it doesn't seem to be
I would like to rescue the fork and keep the cantis if at all possible since they are both original to the
bike and quite distinctive and interesting.
Thanks for any advice.
