Okay so wifeys car had a hard line rust through. I need to replace both front hardlines. My plan is to buy a long roll of the AGS PolyArmor brake line, a spring type pipe bender, and a flare tool. Already have several pipe cutters. My main question is do I NEED to get new hardware for the fittings or can I just cut the old lines and remove/re-use the threaded pieces. ALSO, I've never actually done this. I'm quite confident about the procedure but I'm wondering if there are any tips I should knbow about before starting.
