Powermaster rebuild

To Quote Herman Munster ,
"Darn,Darn,Darn" didn't work, No power assist. light turns off in ~ 7 seconds. No brake light. But no power assist and the pump side well does not come back up when you step on the pedal . Stays fully charged . Now this is a used PM . Original problem pedal was stuck 1/2 way.
I am going to try with the ordinal that was on the car. If that doesn't work , i don;t know. Really don't want Vacuum and hydro boost.

I don't want to be a Power Master Master
. When "bench" bleeding it the pedal went all the way to the floor & fully back up , Once I got the air out . Reconnected the brake line loosely and allowed any air to escape tighten them had a nice firm pedal . powered it up pump ran for ~10 seconds , brake light went off after ~7 seconds. The pedal feels the same. And as far as I can tell I put everything back the way it came out and from what I could read on the PDF.The power side reservoir does not come back up when the brakes are applied. Pressure assist at full pressure. Before(attempted rebuild) the pedal was stuck 1/2 way down. Wouldn't pull back.
Now my original the brakes were dragging took it ~ 5 seconds for the pedal to return. that is the one I am tiring next.
Could have went flying today
Well at least the new Passenger side front upper control arm in

I'm not sure, I don't think the reaction disc could cause a return issue but not certain. It sounds like the booster section is still trying to provide power assist despite the pedal being released, which I think would be something going on with the valving inside the power piston #25
Every thing in there looked OK, The only I did not do was the the "O" ring on the piston guide/stop (The part closest to the pedal. When it came apart the piston in #25 where stuck. But they where free when it went back together. Unless I rolled a "O" ring.
I bought a used Power Master and attempted to rebuild that one yesterday. That one does not have a flanged pin.
I don't see how the pin can stay in place without it.
I agree , but it is what it is. I will tear that one down again and take pictures. The reaction disk has to be holding it in place. I am beginning to thing that this power master is not out of a GN.
