Bad slave or master cylinder or simply air?

1 year ago i replaced a bad booster, master cylinder, both calipers and rear cylinders (drums)

brake lines in the rear..

now on this vehicle..

The rear passenger tire is locking up only when the brake pedal sticks about midway..

the only way to get it to release is to press the pedal FURTHER down and it pops back up. before i bench bleed a new master cylinder,

Update:

Update: 2/6 removed the master cylinder to check the booster for signs of a cylinder leak and also I couldn't get it to stick My wife also stated that it hadn't stuck all day..

Now I am concerned. I have a new master cylinder ready and the old one is acting fine when I did nothing.
