2003 Mazda B3000 Replace front disk brake pads and pedal no

I removed the original pads, still had life, pushed the pistons all the way back into the calipers (after venting the fluid reservoir cap) to allow clearance for the new pads, replaced and lubricated the slide rails installed the new pads, and remounted to the rotor. I then put the cap back on the reservoir tested the pedal and it felt fine. Started the vehicle and then tested the pedal and it goes all the way down to the floorboard with some braking action that will stop the vehicle. After a short drive, I feel like the pads are dragging and of course the pedal really fades when the engine is running. I then proceed to bleed the front brakes, retested, no improvement.

Does the master cylinder need re-bleeding now. No check engine light.

I appreciate any insight anyone can provide, not my 1st brake job, but it's been awhile.
