What causes pad taper? (ceramic pads)
I just changed my pads back to the stock ones--C5 Z06 pads--the OE pads still had over 1/4" material left, so they were almost new.
The ones on the car were ceramic--and the pad wear was the worst by far I have ever seen. Taper was incredible, dramatic, on all 4 pads (inner and outer pads for the front 2 rotors). If you looked at the pad from the top, with the length of the pad running from top to bottom, there was taper at the leading edge (nearest to the the ground) and the trailing edge (nearest to the engine compartment). I would say that only 1/8" or so was left at the exteme areas, where as the rest of the pad had 5/16" or more left.
I hate the ceramic pads, I will not run them again (not my idea anyway--bought it like this)--but what could cause the wear on them to be this poor??? I don't want to see the Z06 pads do this on a track day.
I should add that the Z06 brakes are stock on this car -- rotors, calipers, etc etc etc.
Thanks

You had taper at both edges? leading and trailing? I don't think I've ever seen that.
You can have taper from leading TO trailing, and radial taper (from center of wheel outward). The former is due to gasses and such from the leading edge preventing the trailing edge from making contact. The latter is due to caliper spreading.
Ultimate solution is unequally sized pistons and opposing piston calipers, respectively.

I did not replace the retainers just now, they looked fine, and I didn't do anything special to clean the rotor (like turn it).
Anything I should do to prevent this on the stock Z pads? Maybe this is just an issue with the ceramics??
