Cheap rotors and aggressive pads are my suggestion.

I still think something is probably hanging up and heating the rotor(s) non uniformly. Can you see a lot of pad deposits on the rotor? I'd see if a cylinder is bent or stuck or slow to retract.

These were new OEM-ish parts.

Do you have specific suggestions for each? I've got 2 brand new sets of textar pads. Would prefer not to toss them, but oh well.

I will take a look at them at some point. It probably won't be for a week or two though.

Did I use too many words? Meant friction between the pads and rotors. Are the pads grabbing too aggressively, or could they be grabbing inconsistently and causing a pulsing?

Could it be a failing ABS sensor, falsely reporting lockup? How about wheel bearings?

No that's not it.

Yes is the problem.

I don't think it's any of those things. Everything is consistent with inconsistent friction surface on the rotors.

I wonder if you have a bad hub. Check for wheel bearing play.

How could it be the hub if it mostly goes away with bedding and then comes back with a vengeance?

Honestly, I think I'm suffering from the same. My new Zimm rotors and textar pads on the 535i pulse like crazy. I haven't had the time (and space) to go out and bed them, but in my heart of hearts, I don't think it's going to cure it.
