ceramix pads and performance rotors

hey all i had new performance rotors and cermaix pads put on with the new tires last week and they work great now warpage yet. had a quick question i noticed on rotors that it looks like the pads are leaving marks at where they stop like the cermaix feel on them. is this normal with aftermarket pads and rotors.

they are stopping better than stock pads and rotors just wanted to make sure nothing was wrong

this is an 02 grand cherokee

I went to NAPA Ceramix pads last spring on both the Jeep and wife's mustang. In my opinion they are good parts and you are fine. HTH -Bill-93XJ
