Any ideas on what would cause an Eldorado to overheat? And what I can do to repair it.

Let me try to make a long story short. The other night I was going to change out the rotors and pads on the front disc brakes of my 99 accord lx 4cyl. I noticed that the lugs were kind of warm and the caliper was pretty warm as well, it had been sitting for about 1 hour or maybe a little less. I didn't think much about it. Well I got the new rotors installed along with the pads took it for a test drive and everything seemed fine. Well tonight I was out driving it I noticed a smell I didn't know what it was. When I got back to the house it was the front brakes. The lug nuts were so hot you couldn't touch them for a second with out getting burned. The rim felt fine as well as the tire. I called a friend and he told me jacking the car up and spin the tire and have someone stop and try to spin the tire right after they release the brake to make sure the caliper wasn't catching or holding. I did that and it spun like a champ. So I don't think it's the calipers catching. He mentioned something about a check valve when you push in the piston on the rotor. He said if you do it to quickly that it does something with that check valve. Do Hondas have that check valve? His next advice was to bleed the brakes and see if that check valve would reset itself. Have you guys heard of that? What else do you think could be causing the problem? Thanks for any help
