@Blade, having used Brembo SC I too think they're amazing BUT I made the switch to SBS DC for the track and those are a far superior track pad. I did use them on the road and it was dangerous.. I could not keep heat into them!!
@Rossgo, I was going to ask about the foot resting on the brake. Maybe try going for a ride where you consciously don't use the back brake and see how hot it gets then. Furthermore, when you get home, if it is hot stick the bike on a stand and see if the wheel still spins freely or if the pads are engaged
