Shortly after replacing the brake pads on my 2018 Camaro SS 1LE (6 piston calipers and 2 piece rotors), I began hearing a rhythmic clicking/creaking noise under moderate to heavy braking. Road and wind noise would drown it out over 60kph (~40mph), but it was very apparent every time I came to a stop. With the windows up, it was more of a rhythmic creaking noise, and with the windows down, it more of a distinct rhythmic clicking noise. It was definitely coming from the front of the car, but sounded like it was coming from both sides.
I had the brakes apart a couple of times looking for something that the rotor was possibly rubbing on when the brakes were deflecting under load, like a bent dust shield or some other piece of bent brake hardware, but there appeared to be plenty of clearance around the rotors. I finally discovered that the noise was coming from friction between the aluminum rotor hat and the bushings the disk bolts to. Under braking load, the brake disk bushings move around in their respective slots in the aluminum hat, and if there is excessive friction there, it will result in a creaking noise. I simulated this movement by prying between the rotor and the hat with a screwdriver as can be seen and heard in the video.
I suspected that the excess friction was due to brake dust that had made its way in between the hat and some of the bushings. To fix this, I tested each bushing for creaking and if it was, I repeatedly sprayed the bushing down with brake cleaner and flexed the hat to allow the cleaner to flush out the dust until the creaking stopped. This did the trick! Note however, that while one rotor made very obvious noises, as shown in the video, it was very hard to get the other rotor to creak this way, but it was still making some noise when I was driving the car. So, I just washed down every bushing in that rotor. It's possible that simply spraying wheel cleaner on the bushings and then hosing them down with water might have accomplished the same thing.
Hopefully this helps someone, because the noise was driving me crazy!
