That is what I would do. Have you contacted BF about a repair, or about getting parts so you don't have to fab them?

Heat of brazing is lower temp than welding, but both are over the trans temp, and in this case the 4130 isn't an issue anyway. The heat (non-)affected zone is large with brass. Though it doesn't mater. BF uses TIG, Brass, and Silver on their bikes in the appropriate situation.
