Passenger side front rotor has groves

11500 Miles on 2006 , no track or auto cross time : front passenger rotor is developing grooves on rotor while the remaining three are wearing evenly

Um, severely worn pads on that corner? Worn down to rivets causing groove.

Why that one corner only, most likely caliper slide pins seized.

Remove caliper, clean up or replace slide pins. Lube properly.

New rotors, new pads.

Great! FYI, a good way to clean pins is chuck them up in a drill, then use a scuff pad. You can get them very smooth very fast. Use brake lube on them.

If the grooves are fading away after just a few miles, then they weren't really grooves. They were deposits from the pads. Grooves worn into the rotor would take thousands of miles of street driving to wear away, if at all.
