Brakes cooked after 1 lap on the nürburgring

Basically i had newly swapped brakes less that 2K km on them and on the way back from the netherlands i stopped by for a quick lap on the ring with my daily my G20 3 series. Obviously the stock brakes weren’t that good so i couldn’t push the car as much as i would like to (Top speed was just around 200kmph) + 3 yellows in one lap so it wasn’t much strain on the car. However i come back home and now my brakes are basically squeeling the whole time and i wonder if i should probably get them changed again :/ .
