After 189k miles, it's finally time to do the rear rotors and pads. I have had absolutely no luck getting the 1st(right side) rotor to budge. PBBlaster, heat all around the hub and a hammer have had no effect. I've tried releasing the tension on the parking brake cable but have no idea if that's doing anything inside.
There is no movement at all between the rotor and hub when I pry on the back side. I removed the rubber plug for the star adjuster but it doesn't feel like it's moving.
What am I missing?

 

nothing, sometimes they can be a bear. I've hit them so much I've broken the rotor off the hat. Then when they come loose, there can be a rust ridge so the ebrake shoes catch it. Then you have to adjust the shoes looser.

 

Been a while but aren't there two threaded bolt holes in the drum on opposite sides of the hub? Insert bolts. Tighten till the drum pops loose.

 

Drums have this, yes. Rear disks, however, do not.

If it won't budge, consider it a writeoff and start beating it again and again with a BFH. Like Tizz1 said, I've also broken the disk off the hat so be prepared.

 

The OP mentions "rubber plugs and star adjusters". That said drum to me.

 

Inside the rear disks on these models IS a tiny drum brake that is the parking brake. It uses the inside of the rotor hat s a grabbing surface for the parking brake. The disk itself is a non vented type that slides over the hub like most disk brakes. I could be wrong saying there were no holes, but I don't remember them the last time I did my rear brakes as I have the rear disks on my 02.

 

Hey, I learned something. Thanks

 

Now that I'm convinced it indeed is a rotor take a look at this simple trick. I like the producers video flare too. Recommend you do a better job of making sure the nut and not the bolt maintains contact on the rotor if you plan on having them turned.

 

Well, I did what any logical person would do and made an appointment to get the work done. After 4-5 hours with absolutely no progress, I threw in the towel. The final straw was after I fabricated some flat stock to bridge between the studs and then used a 3 jaw puller along with heat and a BFH and had nothing to show for it. I'm guessing that it's hanging up on the emergency brake but I'm done.
The shop I'm taking it to said that they have had to break the rotor in some cases.

 

C4 maybe?
