Soft pedal

Last track day the organizer threw the checkered about half way through the lap, so we only got a very short cool down. Aside from pad deposits (see other threads), the pedal felt consistent throughout the 20 minute sessions. After a session which had very little traffic, I drove around the paddock for ~5 minutes to try and make up for the very short cool down lap. Ended up having the pedal go to the floor as I coasted into my parking spot in the paddock.

I assume this was heat soak from the calipers which caused the fluid to boil after the session? Also, what warning signs should we get on track that the fluid is getting hot...i.e. softer pedal? And, are there any other mechanical points of failure in the system to be aware of?

Fluid was a premium track-capable fluid per the shop...probably don't see many track cars at that shop.
