If your pedal went to the floor - you must've been out there a wee bit too long and not cooled down properly inbetween sessions.
As a minimum you'll need to change your fluid out and probably pads. If things got that hot you'd better hope you haven't warped your discs. if you're going braided lines - most gor for HEL or Goodridge - though if you're planning on tracking more your pockets had better be deep
Plenty pads and discs here http://www.350z-uk.com/forum/viewforum.php?f=157&start=0
