Truck Repair: Quick Question, vice grips, kind folks

Question
Hello Kind Folks,
            If I have already asked this question please forgive me,I will give you a good rating nevertheless.I am for the first time getting ready to replace a brake line from my passenger side wheel and I am no mechanic.I was curious what tools I might need and do I need to take off the whole brake drum?It is on an old 1970 Ford Pick-up.Also,briefly how do I bleed this when I'm done and do I need to bleed the whole system?Any help would be appreciated.
                  Sincerely,
                  Skyler

Answer
take the tire off, pinch the rubber brake line with vice grips, so it cant leak down. cut the lines off flush with the nuts, and use a socket and ratchet to remove the nuts, replace the line, leaving the end fitting a bit loose. have someone push slowly down on the pedal till fuild comes out and tighten it. should be bled good enough there.
