suggest you try loosening the rear brake adjuster on your bike, as a similar issue happened to me on last world presidents meeting in italy when i was riding a multistroodle in similar heat.

the rear brake pads were dragging just a little on the rotor, causing the brakefluid to heat up, and coupled with the ambient heat of that day, caused the fluid to expand just enough to cause the pads to push even further into the rotors, which heated the fluid even more ... and well, you see where this is going.

so ... once the rotor/fluid cooled down, i loosened the rear brake plunger adjustment about 2 full turns, then flushed the fluid. the rear brake never caused any issues for the remainder of the trip.

ciao,
johnc

thanks johnc that seemed to do the trick so far ...when you suggested unscrew adjuster a few turns i remembered that i turned it a few times adjusting my lever awhile back.
