I'm in the process of building a pressure bleeder for my truck, and decided to also make an adapter plate so that I can use it on Mopar master cylinders as well.

Tonight I was typing up a set of instructions to keep with the tank, but I need to know the highest recommended pressure for power bleeding a Mopar's brake system. Will different systems handle different pressures? The system I'll be using it on is for a '70 Dart Swinger, all drum, manual.

Some of the service manuals state requried pressure bleeding pressure. Some systems (but not a all drum Dart) had to be below or above certain pressures because of some hold-off valve or something in the system.
If I can find some of my service manuals I could look up the info.

My all-drum Valiant gravity bleeds just fine. Just open the bleeder screws and it bleeds itself.

I use speed bleeders. They are bleeder screws that have a one way check valve in them. Press pedal down, fluid and air comes out. Release pedal and the valve closes, preventing air from being sucked back into the lines.

I still don't trust those at all. I prefer the old "unscrew and then tighten while there's still pressure pushing out" method. Plus if there's any gunk built up from the rubber lines, it could clog up inside those check valves.
