Hello,
I wanted to bump this thread. I experience the same issue now, and I am pretty sure it did not occur before. I've landed with low braking just like dectenor2 said BTV far at the end of the runway. I exited the runway with about 80C and when I taxi to the gate the temperature goes up really quickly and goes beyond 300C without any manual braking.
And I did check my brakes, they were fully released.
Hopefully you'll be able to fix this little bug.
