      Odd Rotor Wear Pattern

      I have a 14 GT with 49k+ miles on it and it is just 3 years old. I have noticed that there is a rusty ring about 3.8 to 1/2 inch wide on the outer edge of all 4 rotors. I am not having any issues with stopping and no noises or pulsing while stopping. I am thinking it is just the outer edge of the pads that got damaged somehow and are just not contacting the rotors. I have looked at other Darts and the wear patter on the rotors look "normal" to me. I am guessing it is time for new pads and rotors.

      Thoughts?

      I noticed strange wear patterns on my rotors too. On one front rotor the wear goes all the way to the edge, and on the other front it has like 3/16" unused ring on the outside edge. I checked out others' Darts at the Midwest Dart meet, and I saw the same thing on a lot of Darts. It seemed to be completely random on how wide the contact area was on the rotor.

      As far as your issue though, from the picture it's pretty clear that new pads are in order, and it wouldn't hurt to get rotors too.

      The wear marks in the picture are almost certainly from 1 of three things. Worn out pads, or having had worn pads on the car at some time, a stuck caliper or (much less likely) a rock caught between the pad and the rotor. Marks like that are not really a safety risk and your pads will eventually wear into them. Keep an eye on them however because with a smaller contact area, the pads will wear faster. When you replace pads next time, plan on putting new rotors on it as well. That's my take on things. @D2Stanely.

      @SmokyOwl , if the pads are not contacting the rotor square, you can get an area of the rotor that is not making contact. I'd make sure the pads are properly seated in the caliper, that the caliper is not stuck or impeded, and do a brake fluid flush/refill/bleed service. If you have an air bubble in your in your caliper cylinder, you will not get full pressure and the piston can actuate unevenly. Bleed the brakes, pump them till all the fluid coming out is crystal clear. Most brake shops will blee....or tell you they bled the brakes. It is a simple job, get a buddy overm watch some youtub instructionals and you'll be set. bleeding brakes is pretty much the same procedure on any Dodge/Chrysler.

      I checked, I couldn't find anything wrong (or different between the two) with the caliper & pad setup. See the first picture the OP displayed with the 1/4" unused edge of the rotor...that's what I'm referring to. That ring varies from car to car from what I've seen, although I think it's preferable if the worn area extends all the way to the edge. There really isn't anywhere for the pad to not be in proper position and still function normally, and same for the position of the caliper. That's when I started looking at other owners front rotors and found many of them had similar issues. I'm thinking it's a manufacturing defect of some sort from just how many unequal pairs I saw. Maybe the caliper's bolt holes' true position is out of sorts or something.

      The fronts don't look too bad, but there's something wrong with the rear rotor. I would change out the pads and at least have the rotors turned if you can't afford new ones. I run these on all of my vehicles with zero problems in 15 years.

      Thanks everyone for the feedback. I was just wondering if this condition was unique to my car or if it was somewhat common. @viperman96 Thanks for the link, I have ordered the pads and rotors. These were actually less expensive that any options that I have researched lately.
