I replaced the master cylinder and all four wheel cylinders on my 61 Ranchero, bled the brakes and everything felt fine. After driving for less than 10 miles the brake pedal kept getting higher and I could feel drag on wheels. Eventually the pedal could not be depressed at all and the brakes were locked. I released some brake fluid from the right rear bleeder valve and the brakes unlocked. Another test drive and they gradually locked up again. Anybody have any ideas as to how to fix this problem?

When you step on the pedal you are pushing fluid into the wheel cylinders and out of the master cylinder.
What reverses that fluid movement is springs. A lot of them.
There are at least 2 on each wheel a couple in the master cylinder and may be one on the brake pedal.
The springs on each brake do get heated up and loose their springiness. Did you replace those?

With the brake drum off make sure the primary and secondary shoes are correctly installed in the correct position
