Front disc coversion problems

Good deal, no real suprises as far as components go. You could try to narrow down where the air is. (and help on bleeding) Get the appropriate inverted flare plugs for the master cylinder and block off both ports. Pump the pedal until it gets high and hard. Wait a few minutes and press the pedal down again. It should still be high and hard. If it's not, the master is bypassing and needs to be replaced. If you pass this stage, connect one line and bleed the air out at that port by cracking that line open and having one of them yappers push down on the pedal slowly. Close the line before the pedal gets to the floor. Have the yapper release the pedal, crack the line open again and re-apply the pedal pressure. Do this a couple of times until you get a clear stream from the cracked open fitting. Test the pedal for feel and bleed whichever end is hooked up if the pedal is still low/mushy. Get a good pedal? Move on to the other line/system.
Do it this way and I bet you'll find your problem.
