Just had the AWD rear brakes removed and the car's quiter again about 50. Stinking bearings had hardened a little and transmitted an oscilating / vibrating / rubbing noise into the cabin. Rather annoying so much so I could feel it. Other benefit was that I forgot how heavy they were. I reckon I've just shaved .2 of my quarter time :bowrofl:
