I think this describes it perfectly. I also have painted calipers (yellow) but the paint job was exceptional and does not come in contact with any moving parts. Hope the dealer doesn't "blame" this on the vibration. I read that there is a law that states, bluntly put, that if the rotor is warped, they cant blame it on a painted caliper.

This sounds intriguing. I KNOW a car is supposed to have smooth braking, but this just feels different to me.


Will the dealer replace the rotors, you think?


Thanks for the help! OP, glad you posted this.
