I converted to AAJ discs. Used a 1976 Dart dual master cylinder. No leaks anywhere. I bench bled the master cylinder best I could. I bled the brakes using a hose and check valve into a jar of brake fliud. This works on all my other vehicles. I ran quite a bit of fluid through to make sure. Brake pedal goes straight to floor but will pump up quickly and hold pressure. As soon as I let up and pedal comes all the way to the TOP the brakes are gone again and need to be pumped. If I just let up a little I don't lose them. I then gravity bled them all for a few hours.. Two rears at same time , then two front at same time. Still get the same result. I thought I read something about the Dart M/C losing pressure somehow? Or, is it air in m/c? Bad m/c? Any advice is great ... I would loooove to drive this car oneday. -- -- Please address private mail -- mail of interest to only one person -- directly to that person.
