Anyone replaced right rear hard brake line?
 

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.

A good penetrating oil is your friend...................

Yeah I had all that and then some. Ended up resorting to MAP gas and even then wouldn’t break loose. Rounded the nut and then I said “f” it let’s get it real hot and get the vice grips. It blew the rubber line apart, but the nut finally separated. I had new flex lines anyway. Just wasn’t planning on the hard line too 🙄
