Well that's embarassing

You notice that peak temp is down 40% by the time it hits the measuring device.
Yes. The core temperature drops rather quickly as heat is transferred to the other (outer) brake components. We don't have them, but I think the Airbus family has brake fans that are activated for cooling on the ground.
 
Right, but that's a measuring issue like I pointed out, not a max temp issue. Max temp comes right around the point it stops as is shown, it just takes a while to spread to where it is measured, and where it does damage.
We really don't care what the max temp is in the brake itself because the brake can handle that temperature and doesn't present a threat to the airplane. What we care about is the temperature of the tires and hydraulic fluid because that's what will cause an explosion (from over pressure) and/or fire. As demonstrated by the chart it takes quite a bit of time for these critical components to reach their maximum temperature after an RTO. That is what we must wait for.
