I'm 250 miles into my car and had some issues with my model 3 that I needed to take in for repair. I drove a loaner Model S and noticed that the brakes were excellent and made no sound. I did notice that with my model 3, it doesn't necessarily make a grinding noise but there is some "frictional" noise that when I press on the brakes, you can hear it. I braked hard on the S to try it out and it made zero sound. Is anyone else experiencing this on their 3? Is it because the brake pads are new?
