Nothing! I re-piped my 11B in the 80s and so far so good. I re-piped the BL this past autumn and so far, no trouble. I think the wire wrap was a bit of overkill. My Light 15 didn’t have the wire wrap at all. What is important is that wherever the line touches another part of the car, say the brake line rests against the front torsion bar, cut a length of hose to protect the brake line. Like I said, so far so good.
