Scoring of new rotors and pads

I just replaced my rotors and pads and after just over 1000 miles (mostly highway and all on-road) I already have scoring on the rotor. I haven't had a chance to pull the pad yet but does anyone have any thoughts on why this is happening? I checked the hub temps and this hub is slightly warm so it could be dragging a bit, but wouldn't the wear still be even given the pads and rotor are both new if it was?

Ferodo pads, and not sure offhand on the rotors - what's in the AB kit.

No squealing. There is a distinct groove forming though - that's what I don't expect and find dissapointing. I'll take a closer look when I get home.

Thanks

Only thing I can think of is some grit/dirt got in there and is scoring but I wouldnt worry about it.

Looks like you got a "soft" pebble stuck in there which wouldn't cause a noise. Pull'em and check to see if you got junk in there. Check all the brakes while you're down there. The rest of the glazing pattern looks normal except for the groove you got started.

Rotor scoring or galling is pretty common these days because the quality of rotors is not as good as in the past. When you couple that with a really good metallic pad, scoring is the result. Getting a cooler rotor via slotting or cross drilling can help eliminate the problem.
