While attempting to refurbish my brakes, the right rear hard line nut got rounded. The line was so stuck that when applying heat, I put so much in that the rubber line actually blew off before the nuts would separate with vice grips. I tried replacing the fitting and reflaring the line, but ended up having to cut it too short. (Bad tools, inexperience, frustration led to trying to flare it 6-7x) I’m now going to replace the whole line and would love any tips or advice anyone who’s done it can share.
