Finally got them off using, get this, vice grips. Anyways, I now can't get the rotor off, parking brake is off, truck is in park, brake fluid container cap is off. It "gives" a little, but only moves very little, won't come off. We've tried hitting it with a hammer, etc. My truck sounds like it's grinding while driving at low speeds and braking just amplifies it so I am replacing the rotors and the pads. I should take a pic of the pads, you'd be surprised how bad they look. There are small chunks taken out of the pads everywhere and the rotors are extremely grooved. I have duralast rotors I am going to put in, my brake pads are Raebesto's ceramics (SP?) though. Just to let you know, this is the rear, not the front.
