So today I was supposed to switch out my front springs and put on the cobra 13" calipers rotors and ss lines. I was feeling pretty good about myself after I finished the springs and had the rotors and calipers on. When I tried to remove the stock brake lines I couldn't for the life of me get the nut off that attaches the stock line to the hard steel line next to the fender liner. I even tried wd40 and let it sit for an hour and still it won't budge. Am I missing something? I thought I could even reuse the stock GT lines but they don't fit the cobra calipers....WTF. I need help.
