Make it Stop! ('46 Deluxe)

[FortyNiner]

Looking for some help from the brake experts on the Barn (that would be anyone who isn't me).

Here's the deal:

'46 Deluxe Tudor
Bone stock

As part of my resto, I replaced:
Master cylinder (twice - as part of my trouble shooting efforts)
Wheel Cylinders
All lines / hoses
Shoes
Springs

The drums were not changed.

After reassembly, I have adjusted the shoes so they are just off the drums.
The MC was bench bled
The whole system has been bled at least four times
The system doesn not leak anywhere

Here's the issue: I have very poor to no pedal pressure. if I pump the pedal a few times, the brakes will function and stop the car. Needless to say, this doesn't make for a safe ride. Searching the Barn gave me some tips - that I have followed - without real improvement.

My question: What am I missing? What did I do wrong? Should I do the Bendix conversion?

Thanks!
