start van, brake pedal goes to floor

What is your question?

Right front caliper siezed. I changed rotor, both front calipers (bleeder valves on top) bled from r rear to l front, hard pedal. Turned on motor, pedal went floor. I replaced the master cylinder, bled from r rear to l front, hard pedal. Turned on engine pedal goes to floor ,no brakes. No leaks anywhere.

What makes this problem better or worse?

My frustration

How long has your 1998 Dodge B1500 had this problem?

I have been messing with this thing for 3 days
