so much so that when i touched it the skin was seared off my finger. The other rotors don't do this, they only get mildly warm. I changed the brake caliper because the heat can only be caused by friction from the brake pad. Even the lug area of the rotor is getting blistering hot after a few minutes at highway speed.
Changing the caliper had no effect. I bled the brakes when i put the new caliper on the offending rotor. Why else could the brakes be causing so much friction if not a sticking caliper?

Good evening,

The brake hose is a very common failure for collapsing and not allowing the caliper to release and overheating the rotor.
