Lots of reading here and at least be thankful Kia would replace a wearable part in a 1yr/12k miles. Let's be honest, dealers are not going to advertise this on megaphones but it takes a community like this to bring up some of these issues. Also if the OEM rotors are that crappy, you have plenty of aftermarket options at very competitive prices to include drilled and slotted. I personally go with slotted rotors if the option is available over drilled. These will most likely double the life of the current OEM rotors.

Does anyone have a spec on thickness of the rotor?

I've noticed a noise when I stop from high speed like there is a rough surface on the pad or rotor. Like a rrrrrrrrr-rrrrr--rrrrr noise. Maybe it's what you guys are saying is grinding.

It's not pulsing yet, but I'm pretty sure it's going to come back. Funny it's not all of them. The one with the brake issue is a 2019 GT1. I also have a 2018 GT2 and the brakes are 100% fine.

thats exactly the sensation, did you have rotors replaced on '19?

The brakes also squeak on the 19 before new rotors/pads and I've noticed it coming back again a few weeks after the rotors/pads

sounds like we both got the "new and improved" rotors

that is the opposite of the proper bedding procedure.

When following these instructions, avoid other vehicles. Bedding is best done when traffic is light, as other drivers will have no idea what you are up to and may respond in a variety of ways ranging from fear to curiosity to aggression. A police officer will probably not sympathize when you try to explain why you were driving erratically! Use common sense!
  1. From 60mph, gently apply the brakes a couple of times to bring them up to operating temperature. This prevents you from thermally shocking the rotors and pads in the next steps.
  2. Make eight to ten near-stops from 60mph to about 20 mph. Do it HARD by pressing the brakes firmly, but do not lock the wheels or engage ABS. At the end of each slowdown, immediately accelerate back to 60mph, then apply the brakes again. DO NOT COME TO A COMPLETE STOP! If you stop completely, with your foot on the brake pedal, pad material will be imprinted onto the hot rotors, which could lead to vibration and uneven braking.
  3. The brakes may begin to fade after the 7th or 8th near-stop. This fade will stabilize, but not completely go away until the brakes have fully cooled. A strong smell from the brakes, and even some smoke, is normal.
  4. After the last near-stop, accelerate back up to speed and cruise for a few minutes, using the brakes as little as possible to allow them to cool down. Try not to become trapped in traffic or come to a complete stop while the brakes are still hot.
  5. If full race pads, such as Hawk DTC-70 or Performance Friction PFC11 are being used, add four near-stops from 80 to 20 mph.
After the break-in cycle, there should be a slight blue tint and a light gray film on each rotor face. The blue tint tells you the rotor has reached break-in temperature and the gray film is pad material starting to transfer onto the rotor face. This is what you are looking for. The best braking occurs when there is an even layer of of pad material deposited across the rotors. This minimizes squealing, increases braking torque, and maximizes pad and rotor life.
Thank you!

I had my buddy recheck, he found no TSA fro the brakes, I think Kia is simply making use of the manufacturers warranty.

The website for the rotors has no specs whatsoever on these. Just for the ones who would want this info, you should at least weigh the new ones and the old ones for comparison. Rotor thickness would not hurt either and update another thread running with detailed specs.

Give Nick a call, he is always in the loop as to when they will have more in stock, they are using his Stinger for product development.
