I have a model 3 performance with the factory brake equipment. I was driving spiritedly through a canyon road and I felt my brakes slowly fading, and I got a message saying brake temperature high, braking performance reduced, so I eased off the brakes. I pulled over to check the rotors, and they were glowing orange! Now, even though this surprised me, I know brakes heat up an intense amount as there is another car I have for track use. Although it has carbon ceramic brakes and does not glow.
I immediately drove at speed to cool the brakes for a couple miles and then parked again to check the brake pads. They were all good. My only concern is that the outer ring of the rotor (not the face, on the edge) had some corrosion on it due to the heat. I’ve had this happened on a Civic Type R I used to own.
I just wanted to ask people who do autocross or track events know if this is ok, and if there’s a way to clean. I don’t care about the aesthetics. Just want tips on what to look out for. I know when hot, you shouldn’t apply the parking brake as it can stick to the rotor.
