I changed out the Hawk blue track pads a couple of months ago to street pads.
I've changed them 3-4 times in the past 8 months. The rotors have always been like glass and I bed the pads in right after install using 70mph to 40mph smooth decels.
I went to put the track pads on yesterday and noticed the rotors were all grooved up. Hasn't affected stopping performance (at least what I can feel on the street) but clearly, they weren't like this when I last put the street pads on.
Here's what they look like. Its never happened to me before, what causes this?
