If you have a soft pedal, Def flex brake lines, Def master cylinder or out of adjust shoes or AIR in the system. To bleed out the air in the MC, just mount it in the car, leave the lines off, use the little red nipples and clear tubing, and use the brake peddle to bleed it. Put shop towels under it to catch drips, when no more bubbles, remove the nipples, and screw on the lines, clean up any drips, there wont be many, and refill MC, all done. EZ PeeZe. Brakes are not that difficult IMO.
