Uncle Sam, We have a brake thread going at the present time, I'm sure you'll find it on the first page. Please post your commentary in that thread.
Sorry for your trouble however your assertion is correct I believe. When you cool the caliper, most often and if it isn't totally damaged, the piston pressure will release and relieve the tension on the brake pad. This has been my experience as well.
(just cut and copy it)
I am going to lock this thread down.
