Recently I noticed the drivers front wheel is getting alot more brake dust compared to all the others which are pretty dust free. I looked at the rotor on that wheel and it has dark rings/tint and I can feel they are not as smooth as the other 3 rotors. I did some research and think the caliper might be binding/dragging a little. I get the same dark /tint/ ridges on all 4 rotors after some hard braking, but it stood out this time because it's just on one rotor and I haven't braked hard for awhile. Any ideas? Thanks.
This is what all the good rotors look like
This is the one that has alot of brake dust. Don't mind the gold color of the photo. It was the lighting.
