Thanks all for the comments.
Byers Chevy, south of Columbus replaced the brake fluid. I asked for a high temp fluid if they had it. I don't know what they used; the FP-Number on the ticket is M0C06001, but I suspect that's just the work code for a brake flush. They are going to check my brakes Friday.
Due to personnel commitments I won't be able to go to the track again this season so I'm not going to spring for track pads. My plan for upgrading brakes is to buy a 2017 1LE at the end of the year or early in 2017.
Air temps were relatively cool so the track temps had to be very friendly. Over heating brakes probably had more to do with my poor attempt at track driving. I feel that I got only got turns 1, 3, 4 and 5 (end of the back straightaway), down reasonably well, even drawing some praise from the instructor. I'm sure those are the easy turns. I never felt like I had tun 2, madness, and the carousel at all right. I braked kind of hard in Thunder valley once and my instructor freaked out.
