Truck Repair: Quick Question, sears craftsman, bleeding brakes

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,

Answer
Removing old brake lines can be a pain. It is not necessary to remove the brake drum. The tools you will need should be basic combination wrenches, a set of line wrenches, and a set of vice grip locking pliers. I would recomend purchasing them from Sears (Craftsman). The sizes would be from 3/8" to 3/4" on both type wrench sets. I would recomend to bleed all the brakes. It will take two people.
One in the truck and one bleeding the brakes. 1st fill the master cylinder with brake fluid. Make sure master cylinder cap is back on before bleeding brakes to keep fluid from going every where. Have the person in the cab to pump the brake pedal till it gets hard and hold pressure. Have the person bleeding brakes loosen bleed screw on wheel furthest from master cylinder. Brake pedal should go to the floor pushing air and brake fluid out bleed screw. Before letting off brake pedal tighten bleed screw. (If you let off brake pedal before tightning bleed screw air will get in the system.) Do this on till you have no air coming out bleed screw. Do same on next furthest wheel till all are done. Check brake fluid level in master often to make sure it does not run out of fluid. After you finish you should have a firm break peadal it should not go to the floor. If it does you still have air in the system.
Hope this helps.
