When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid.

When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible, of course, and the brake pedal goes to the floor instead of moving the caliper pistons. Production cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on race cars.\u003c\/p\u003e\n\u003cp\u003eRace-only brake calipers generally come with titanium caliper pistons for one reason: titanium has low thermal conductivity. This means it's very bad at transferring heat, which is good if you're trying to keep your brake fluid from boiling.
