I’m sure many will chime in here, but after doing many many many track events, I will try to answer some of your questions and give you some advice.
First off, you need brake cooling ducts. Period.
Now that’s out of the way, I would say it is not normal to lose your fluid out the bleeders after the fluid boils. My last track event at Road Atlanta I did lose some fluid out the front outer driver bleeder, but never lost my pedal, didn’t have any smell. I believe the bleeder screw was a little loose. Luckily it didn’t affect my paint on the car.
The one time I did boil the fluid was at Carolina Motorsports Park where there are moderate braking zones, but little straights to get them cooled enough. I lost pedal pressure near the ends of my 25 min sessions, but after driving around the paddock it came back. I did not have any fluid leak from the bleeder screws. I absolutely recommend changing the fluid after that circumstance.
I’ve got nothing for you in regards to your smell inside the cabin. Sorry.
