Sorry to reawaken an old thread, but this may have just saved my sanity...so there are thick brake bushes, and there are thin brake bushes!
Last weekend I knackered three oilite brake cam bushes trying to fettle them to size. I assumed that everyone else was just a more skilled fettler than yours truly! It took me a step further to getting a lathe, that's for sure!
I did notice that one of the bushes I took out, or at least its mortal remains, were not bronze. So now I know - zinc. The one I took out was perforated, or perhaps just dinged, with lot of little dents.
I re-bushed a crossshaft a few years ago and used a bit of zinc spring interleaving to do that. So I assume the same would work here, provided it's the right gauge? No "special" quality of zinc required? I'm always a little nervous going off piste with brakes. Most other experiments, if they go wrong, cause the car to STOP going. Brakes, on the other hand...
