Excessive rotor heat
I have a 2000 mustang. The other day the front right brake began to smoke, so I got home and pulled the wheel and checked it out. I greased the slide pins and put it back together and it was fine for about a week and then started doing it again.
This time I replaced the caliper, brakes, and guide pins figuring that would certainly fix it. Got it all done and test drove it only to find out the rotor was almost twice as hot as the other side when I parked it (over 400*)!
Any idea what it could be? I also noticed after new caliper was on, that it was very hard to spin the rotor by hand (almost impossible). I know that can't be right. So what is wrong?
