So today I went to a track day and did several very powerful brakings, but also did a cool down lap. And on that first stint, my pedal got soft. Ok, I'll change the brake fluid... But stopping in the paddock, the brakes were smoking a bit. I immediately rushed out and did a few km outside, cca 80-90km/h cruise to cool the brakes down. Worked well, they were cool. But then when I checked the paint markings on the rotors, they all changed colors, indicating that the rotors exceeded 630°C.

And that was just after one short stint. So later when i drove, i was very gentle, all good...but now when I was going home on the highway, I feel a slight judder around 120km/h, and when I brake, the steering wheel shakes a bit.

Did i really manage to ruin completely new rotors in ONE stint? Or is it possible it's just brake pad deposit?

Thanks for your answers.
