So i was driving to the airport the other day and i noticed that my wheels were making noise when i tried to brake. Then later a whining noise started coming from my rear right wheel. I checked it out and turns out that i have a frozen caliper. I'm guessing that its frozen because my brake is clamped onto my disc. Anyways, I have no idea what i'm supposed to do. I remember threads about it a while back but search isnt working so i have to ask. any help is greatly appreciated. thanks in advance.
