2005 Tahoe brake peddle to floor

[Mjames9905]

Hi 2005 z71 Tahoe. Original problem was brake peddle went to floor while girlfriend drove it. She limped it home with barely any brakes and peddle to floor. Was out of brake fluid. Found sign of leak by master cylinder. Replaced master and brake booster. Then when I went to bleed brakes, discovered bleeder valves had been eaten up and were seized, so I replaced calipers, rotor and pads on front. Rear were fine. Bleed brakes. Peddle still goes to floor and you literally have to pull up peddle to get it to return. When doing bleeding, on a trickle was coming out. For some reason seems like it's not pressuring up. No abs codes, does say service brake system. I find no sign of leaks anywhere else on truck. Any ideas would be appreciated.

Probably need to bleed again to get any air out.

bench bleed the master, then do the truck
