The brake pedal slowly travels to the floor. I replaced the master cylinder and bleed all 4 calipers and still get a spongy pedal that slowly bottoms out

Yep, this is common when one of the brake caliper slides is seized, or you have air stuck in the ABS unit, here is a guide and a video to help you fix the issue.
