Do you have a firm brake pedal?

If you have access to a power bleeder then it couldn't hurt to try. I know it took 2 people, a few hours, a lot of brake fluid and patience when I did mine.\nYep, pulling those rear wheels and drums is a lot of labor... I hope I don't have to mess with it again for a long time!

How much pressure would you say is coming out of the bleeders ? Alot or just dribble ? Are your wheel cylinders good ? I had to replace all mine. They looked fine until I peeled the rubber cups back and they were solid rust. Also possible the Booster is bad.\nI am sorry I didn't flush mine out completely and switch it to DOT 5 fluid. That is what My Deuce uses and it does not rust out the insides nearly as bad as DOT3.

Good flow on the rears, not so good on the fronts. The wheel cylinders are working and look pretty good. I have ordered a power bleeder. I have been soaking the bleed screw on the rear booster. When the bleeder comes in, I'll go for round three on the bleeding.

That could be a bad booster if it does not improve or the Proportioning valve is stuck. Is the Dash brakelight on ?

[FSJNut]

The plunger on the proportioning valve seems to pull in and out freely. I don't know if that means anything, but it does move.\nI did see the dash light come on for about a second one time when I hit the brakes really hard.

That means there is uneven pressure. Could be air, could be something else. How old is your master ?

3 weeks old from Alretta. Geoff is awesome, BTW.

Unscrew the vacuum line at each booster and look for signs of brake fluid. You may have a stuck booster.
