Well in that case....

If you wanted to know the pad temperatures, Rick...I would assume like before that the pad temperature at the contact patch would be the temperature of the rotor at that patch....We could assume no heat transfer due to air movement, and I could still give you a formula to find the cross-sectional pad temperatures.

Given what Richard has explained to us, heat is disipated through the rotors....so if your formula has the max temperature of the rotor, then this is a convection heat transfer from air to rotor.

q(local heat flux) = hA (Trotor - Tinf)

One could assume that both sides of the rotor get air contact, so the A in the above equation would relate to the area of the rotor *2.

So how are you going to continue now, Rick? You gonna base your experiments on pad heat and then rate of rotor heat transfer? Those seem like two good spots to focus on...Of course you don't want to burn up your pads...and it just makes sense that the bigger the rotor, the more braking and cooling you could get.
