I've experienced this with my Stoptech BBK, along with a minor version on the street where there is a small amount of variability in brake pedal travel/pressure from application to application. Sometimes it's rock hard, sometimes there's a small bit of squish... And this happens from block to block, during regular driving around town.
The shop I take the car to is very reputable (they even race their own 135i) and I trust their work. The wheel bearings are good, the brakes were bled a few times with Endless RF-650 fluid, etc...
They said it's the classic symptom of knockback, but I'm struggling to believe that I could get hints of that at 35-40 mph surburban driving.
It should be noted that on test drives, they don't see (or more accurately feel) this issue. These are good & experienced guys. But I swear that minor variability is still there for me. My Land Rover LR3 and VW Passat have more consistent brake feel around town, and I don't recall the variability with the 135i OEM setup.
And then you said...
