The clutch pedal in the trans. cover for my roadster has almost 3" of movement instead of the usual 1.5" With a new pedal support bolted in, the play is still over 2" so I need to work on the pedal ramps also. I have use a mig welder to build them up in the past, but wonder if braze welding them might not be better. My only concern is whether bronze will last the distance. I don't want to have to do it over again too soon.
Anyone tried this before?

Steel is what you want for the pedal cams.
Allan, Brazing isn't a welding process. It's more akin to soldering, because you don't heat the base metal to the melting point. With welding both your filler and base are melted together. Soldering or brazing heats the base material enough for your filler material, which melts at a lower temperature, to fill gaps between the molecules of your base material. When everything cools and solidifies you have a joint.
Has your MIG weld build up failed you? If not, why try a different method? You know what they say, "If it ain't broke,don't fix it!"
Thanks guys. I was looking at the bronze as a better wear surface, like bronze bushes on shackle pins. It is also a little more controllable, leaving less material to be removed to bring things back into spec.
Am i correct in aiming for 1.5" of pedal travel?

I don't know about getting it in Australia, brass brazing rods come in different hardness's. You can get the hard type for building up wear surfaces if you want to go that route.
