Have you checked front sway interference with the caliper while turning?
I was having what I perceived as knock-back on my z4m. Checked hubs, changed pads, flushed system, etc. etc. Nothing worked and would occasionally get a super soft pedal going to the ground (and the corresponding "code brown" in iffy situations).
Finally broke down and took it to my indy and he found that the aftermarket sway I put on this year (H&R 30mm bar) actually makes contact with a front caliper under significant turning conditions and push it out of position. Apparently, H&R doesn't recommend this bar for the Z4M (though various sites like ECS say otherwise). Needless to say, i'm putting the stock bar back on. YMMV!
