Default Rear brakes problem

I have been having this problem for awhile now. The right rear brake rotor is always hot as hell when I am done driving it, way hotter than the other ones. Then recently they began to make a lot of noise. Figured out the pads were shot, never heard the wear indicators or anything. Replaced the pads and had the rotor machined down.

Now the rotors are still hot as hell, so hot you can feel the heat on the wheel itself. They have got to be sticking or something because none of the other ones are like this. We even unhooked the e-brake to see if maybe that is what was causing the problem. Thats not the problem since they are still doing it.

So is there anywhere that I can grease or lube up so they dont stick or could this be some other type of issue?

Maybe a seized piston in the caliper? How about a wheel bearing going out? Have you jacked up the rear end and turned the wheels by hand to check for excessive drag?

I havent noticed any thing abnormal, the other side felt the same.

Might be taking a while to release. Take off the caliper and see if you can push the piston back in then use vice grips to hold the piston from popping out when someone else lightly presses the brake down, does it come out smooth and fast? does it release fast? Its probably just a seized rotor, it happens to back ones cause they dont wear out very fast and the piston stays in the same spot in the bore for a long time, also water in the brake fluid can make a little bathtub ring type thing inside that the piston is getting hung up on, Calipers are fairly cheap, just change it out.

Could be the caliper of the brake hose. Both fairly inexpensive. If you do the hose make sure you spray where it attaches to the hard line with PB Blaster or other good penetrating oil. Using a fitting wrench will decrease your chances of rounding the nut off.
