Its the phenolic pistons in the calipers. I am not sure what the issue is, but calipers with phenolic pistons will start to seize up and the brakes will get hot.
The front brakes on my old '91 Ford Ranger does this, generally at about 100K miles on them, had it happen twice now.
Co-worker had this happen on one of his rear brakes on his '04 Ram 3500 recently. He changed the caliper and we bled the entire system and even took it out on wet grass and cycled the antilock brake pump to purge the old fluid out of it. A few weeks later he was on a trip to Florida and called me from about half way between his house and mine. Had the other rear brake seizing up (fronts were replaced a long time ago) and I told him to go to my house and I would meet him there with a caliper. We did a quick pit stop change of the caliper and he went on his way. A guy at work does lots of auto work for hire from a shop at his home and he says the phenolic piston brakes always do this.

And if a person, especially living in the salt belt, does not adequate lube the slides, that is the second most likely cause IMO.
No "light grease rubs" into the pores of the steel. First, it sounds dirty or you're having too much fun rubbing your pins...
Anti seize that stuff and be done with it.
