My last PIR Quattro Club track event left my UFO brakes cooked and
vibrating badly.  A post mortem of the system revealed that I had more
pad lining material glued to the rotors than I had on the pads.  My fix
was to take a disk grinder with 60 grit to the accessible friction face
of the rotor and an emery cloth wound whip stick to friction face that's
inside the mounting bell (you've gotta see a UFO rotor to understand
this) and grind away the deposits.  This resulted in getting rid of the
vibrations and also got me real serious about replacing the whole
system, which I have since done.
