'91 200q20v, 110k miles
Pulled off my UFOs this weekend (they have about 40k miles on them).  Couple
comments:
The pad covers pretty much the entire surface of the rotor, from inside to
out.  The rotors are vented, and open on the inside (near the hub) and outside
(near the wheel).  Over time, the open portions of the vents starts to rust...
the rust moves into the metal, under the surface where the pad rests.  As the
metal rusts, it expands; the pads wear on it, the surface gets uneven, and the
inner and outer edge of the pads get worn deeper than the center area of the
pads.  This leaves a "lip" on the inner and outer edge of the rotors, both
sides.  I'd say this would be a good reason for the rotors occasionally
"warping"; some good hard braking will set the pads to the actual shape of the
rotor surface.

Question:  anyone in the New England area have an on-the-car brake lathe that
can true UFO rotors?  The pads have about 1/3 to 1/4 their life left, and I'd
like to _not_ install the new pads I purchased until I have the rotors turned.
Per Mr. Bentley, the on-the-car lathe is the way to go on UFOs.  I have not
approached a dealer about this yet.
