Jam a hose on the connector, plug it back in the rear hole. Put a finger on the other port and blow. That should be enough, but you might want to sit down first.

So, got it all rebuilt and back in the car. New servo is in place as well. Hooked up a bleeder kit from the line hookups at the master to the reservoir. I don't seem to be getting fluid from the cylinder to the bleeder kit when I pump it. Any ideas? I'm gonna pull it when I get home because I'm afraid the plunder bit in the servo might have fallen out or something. Any ideas on what I'm doing wrong if this is not the case?

I did one recently for a friend, using a new M/C. In the end, what I did was get my friend to pump the pedal, while I held my fingers over the output holes of the M/C (the threaded parts where the two brake pipes that feed the callipers screw in). When he pushed the fluid pushed my fingers out of the holes, but on the pedal coming back up, my fingers sealed the holes so air could not get back in. Half a dozen pumps and all was well.

Seals in the MC are tapered and seal more tightly when pressing against the hydraulic fluid, but they should easily release and tend to spring back a tiny bit.
I dont think that that you could easily assemble the MC piston if your seals were too large. Let's assume the kit is valid. Are you sure of your order of assembly? This is a 74-77 MC but similar

Can you take a picture of your entire assembly the way you are installing it?
I pulled my master a few years ago and had it painted and back in working condition within the day, something must be out of order to make this such an issue. Are you using brake fluid to lubricate it when assembling?
Did you look inside to see if there is any gunk inside the cylinder bore? What brand is the rebuild kit?
