Hey Alaska, was just looking through the manual, as for repairing it, I didnt see anything on the subject. I would think with something to flare the existing line, that it would be possible to cut out the leak and put a new piece in.

As for removal and installing the brake pipe, the vx disc is very basic, saying that there is just a couple plastic clips to undo near a cross member. And of course both ends of the pipe, I have no idea if a replacement would be pre bent or if it can be ordered in straight lengths
