No booster on my setup....just the new dual master and brake safety block, or distro block. So, after some time, here is where things stand. Had the older master rebuilt by White Post Restos.....great sleeving and rebuild. This time used the lines to bench bleed, and as noted above, did the bleed again after finding air sucking in one wheel cylinder during bleed. Replaced the one wheel cylinder, as noted by Big John, and also suggested by rebuilder. So, then gravity bled because my help was busy. No pedal. Got her to pump brakes later, and no pedal.....not happy. So, starting from scratch, found two wheels a bit loose on the shoes.....not much but not tight. Also, was not getting enough fluid thru rears. So, start over with pressure bleed on reservoir.....a lot of crap to stop the air leaks on the adapter. So with very low press, maybe 15 psi, began at back yet again. Bled rears and found some air in the RR. Then, the last one, LF, found a bit of air there too. So, after my trials, I have some brakes. Now what I like is a rock hard pedal. I have maybe 90% and the wheels will lock up on gravel drive now.....and need more road test to seat the new shoes. So, for today, I am a happy guy with enough brake to road test. Good thing that when I was young it was not this hard, or I would have bailed.
Glad to see you don't use a booster! W a good master and good wheel cylinders, there just isn't any need for them on regular passenger vehicles. Now, if hauling heavy loads, say, putting more than 3 tons on the road, I'd want a booster. Otherwise, a well designed system will do nicely without that, as I've found with my pickup truck!
If called on to bench bleed a master, I do it literally; on a bench, to make damned sure the master IS AIR FREE before I hang it on my firewall. That approach serves me well. Also, it seems to simplify testing the wheel circuits to have them disconnected from any master. I found I could more easily bleed the brake lines and cylinders while the master was loose, by virtue of a turkey injector syringe full of brake fluid and a little bit of hose too.
