Ok guys, I need some direction here please. My rear passenger brakes seized since the pads and rotor are extremely low. I bought the parts I need to change them, but I can't get either rotor off. What am I missing. I don't see anything else that is holding them on, but I can't get it off even after beating it.

Thanks guys

Get a rubber mallet and start hammering the back of the rotor in a circular motion. It just Rusted over time but it will come off. It will help if you spray the hub area with penetrating oil

Beat it harder. I had to really beat the crap out of mine. If you have a big sledge hammer, hit it with that.

The only thing holding the rotor if i remember correctly was the allen nut

Yup, it'll go. Make sure the parking brake is off and of course the locking bolt is out. Also, if the parking brake has been run-in and then readjusted, you may need to back the shoes off. Might be hanging on them if there is a lip on the inside of drum on the rotor. Normally I pound on the front of the rim, hard, moving each hit in a circular motion around the face of the rotor.

Great! Well the parking brake was on to keep it from rolling down my driveway...when I finally got it off it came apart. Springs came out and I have no clue what to do know...This is getting to be a pain in the butt

Awesome write up...very helpful...Ok...I tried putting the parking brake on the driver rear. I had a friend help out, but we can't figure it out. This might have been the original problem. It seems this side is always engaged since the rotor won't go back on.

The parking brake won't close anymore even when adjusted to account for a new rotor. I can't figure it out..anyone have this happen to them? Like the parking brake doesn't disengage.

Did you make sure you aren't fighting the slack adjuster? Also ensure that the shoes are seated all the way and centered. If there is any adjustment between the shoes, make sure that is down.

Well, I worked on it a little more this morning. No, luck. So a tow truck is on it's way...I'm done with it.
