UFO Sightings?

Hi Derek,

First, I have a pair of used but true UFO rotors that I could part with.

Pad backing plate against rotor makes a bad noise! This is my passive wear
sensor system for all four wheels, long ago spliced the active sensors out
of the system. But the backing plates first only touch on the unworn annular
rings either side of the pad wear area and, as such causes no harm to the
active rotor surface. You let yours go much longer?

There is no min. safe rotor thickness, IMO. The purpose of the factory min.
spec. is to sell new rotors with every pad change. Yours will probably be
just fine with new pads. My original UFOs are up to 260K and looking good.
