Rotor grooves?

[AUDILUX]

Just had a used set of stoptech brakes installed this weekend, got home and noticed marks on the rotors. I'm pretty sure they weren't there when they were put on, but was wondering what might be causing this? Is it just dirt that got on the caliper and left this mark or is it something I should be concerned about?

Thanks.

Thanks. Yeah, it did go away. I guess it was just caused by small rocks and dirt that got on the pad.

Good to hear. From the pic, they looked fairly deep.
