You clearly have an understanding of how braking works. You'll be fine.
It's the people who don't have that understanding and are used to autocross or tracks with shorter straights and lower speeds that sometimes get into trouble at Sebring. To your brakes, Sebring is 3 minutes of:
Brake from 110-80 (turn 1)
Brake from 95-55 (turn 3)
Brake from 110-45 (turn 7)
Brake from 95-45 (turn 10)
Brake from 85-45 (turn 9)
Brake from 110-70 (turn 14)
Brake from 80-60 (turn 16)
Brake from 130-75 (turn 17)
Lather - rinse - repeat
Speeds are +/- 20 mph depending on how quick your car is, how well it corners, how good you are, and how big your balls are. But, you get the point. Lots of repeated heavy braking, not much time for the brakes to cool.
For the novice driver, it can be worse, because they'll want to touch the brakes in a lot of other places where they probably shouldn't. That introduces more heat to the brakes where they should be being allowed to cool instead.
This PSA is brought to you by Loren, because it's Friday and he doesn't feel like working.
