You need to bleed the brakes after every track session, if you want to keep brake performance at peak. You should also check the dust seals on your calipers for baking. The rubber parts of the caliper do get baked hard on track, sometimes after a couple days the rubber soaks up enough fluid to soften them and they work better.. But if I'm tracking a street driven car I'm going to regularly tear the calipers apart and replace the O-rings, and the dust seals.
The dust seals are optional on a track only car, I don't even install them on race cars.(They just bake away anyhow...)

Aslo when you change your brake pads, and your compressing the calipers, open the bleed screws so
you don't force grungy fluid back into the ABS pump and master cylinder. Instead just let it run out the bleed screws into a catch bottle.
