why is my left brake squeaking and getting ridiculously hot?

What is your question?

My left rear brake rotor is getting super hot when I drive. I looked at it and my slide bolts are perfect, my brake pads have 3/8 of and inch left and my brakes aren’t sticking. There is a little bit of friction but it’s normal. They squeak sometimes when I drive as if something is rubbing because the squeaking gets faster the faster I drive. Sometimes it squeaks and only when I’m turning left, sometimes only right. If it only squeaks when turning, it goes away when I turn the other way. Most recently it just squeaks sometimes no matter what. The squeak will always go away when I step on the brakes. This problem has only been going on for about 2 weeks but it’s really annoying.

How long has your 2009 Hyundai Sonata had this problem?
