Thanks for the helpful info. I just did a pad change and had severe uneven pad wear. The passenger side piston side pad was near metal to metal and the driver side was only about half worn. I cleaned the guide Bolts real good and swapped out the rubber boots. We'll see if that helps any. I guess I have about 6 months to decided on the caliper / rotor upsize. Glad I know it is an option though. Thanks again!
