1995 P32 Rotors Overheating

Thanks guys, I do have the "grooves" like Bud mentioned and I thoroughly cleaned all moving pieces on the caliper with wire wheel brush using a drill. I used high temp grease that came with new pads, but there was not a lot of grease. Should have used high temp wheel bearing grease since I have plenty of that. Regardless, does it not seem odd that both sides would have the problem? Could that point to some other problem? This was my first ever brake job with this type of caliper, so maybe I made a bonehead mistake on both sides; but its not exactly high tech to understand.
