i don't think this is what jim was talking about with his post but yes thermodynamics play a huge factor in a racing situation where the braking friction is tranfered into heat which boils the brake fluid. in this situation you may consider sythetic brake fluids as they have a higher boiling point and tend not to attract moisture as normal brake fluids do. the only real problem with sythetic fluids that i have used is that the pedal or lever effort can be vague compared to normal brake fluids.
