Brake Bleeding Problem

It is better now; which is to say I have resistance/fairly firm pedal with the key off; but with the engine running it is still going pretty much to to floor. So while terrible, it is an improvement over day 2.

I am going to repeat the process again this evening hopefully, and maybe it will improve again after making another. It is interesting that I don't think I have seen any air from the fronts, it does seem as though it is the rears that are the issue.

What is the device on the floor? Seems awful robust for a mere catch can...?

Thanks!

Did a complete pad and rotor swap. When pushing in the caliper piston, I opened the bleed screws to let the fluid out that way. Did a pressure bleed and ran clean fluid through - no pedal pumping, reservoir never ran dry, no line was ever cracked. Pedal is mushy with engine off, but gets to a firm spot (standing on it with both feet and all I can leverage). With engine on and some level of consistent force on the pedal, it sinks slowly to the floor. I have seen all the posts and it looks like a thorough bleed with the software is in order, but I am at a loss to actually explain what has happened.

Any insight from the experts? This is messed.

Thanks.
