I can't weigh in on bbk but I can tell you what made a big difference for me. Bleeding out all the old dirty fluid along with stop tech sport pads all around. Also added the master cylinder brace & it made a huge difference from what I had. It was almost scary before as it felt like I might not be able to get stopped. The sport pads have a little less cold bite but not too bad, & are way better once they are warm than what I had. All for just a little over a hundred buck & a few hours time.
