No Leaks, No Brakes

I pulled the drums off the 67 Cuda over the weekend. Trying to figure out why the brakes don't work and go to the floor. The drums, shoes, and everything else in there look really good. There are no leaks in any of the lines, ect. Master cylinder is full of fluid. What are some of the other thing I can check? Maybe the master cylinder push rod is stuck?

May eventually as least do a disk conversion on the front with a new MC but for now I would like to get the drums to work. I do have a Ford 9", not sure if that matters much. The PO did drive the car, though it was about two years ago.

Any ideas?
