What I really need to do for my state inspection is replace both rear wheel hub assemblies (04 Sonata without ABS) and I was able to get the entire hub assembly out, but it also still has the (very rusted) backing plate and the parking brake/e-brake assembly attached and for the life of me I can't see how to remove the hub assembly from the parking brake assembly. I titled it "replace emergency brake shoes" because I would assume that the wheel hub assembly has to be removed in order to change the parking brake shoes. This is the wheel hub assembly I bought, and it sure looks like the one I'm replacing.

This Sonata is on the east Coast, so it's pretty much nothing but rust underneath right now, but I'm hoping to get another year or two out of it, and they said I needed both rear wheel hub assemblies for my state inspection. Right now the entire assembly is just hanging by the parking brake cable, until I can figure out how to separate the two

I live near Philly and did the same thing a couple years back on my 03. You have to pull the rubber plug from the back. You will see a self adjuster in there and you have to loosen the adjustment. Chances are, your adjuster is rusted and will need significant coaxing to loosen up. Since you are replacing the assembly and using new pads and rotors, use some WD-40 or other lube and let it set some. Once the pads shrink in, you will be able to pull the rotor off and replace parts.

Go to HMAservice.com and create an account. It is a valuable online repair manual and it's free.

Good luck, Chris

MyKids04Sonata is an unknown quantity at this point
For anyone with this same problem...
I am rebuilding a salvage 04 Sonata (2.7L) GL.. When I went to pick up the car the driver's rear wheel was locked up tight. The emergency brake shoes were bonded to the drum and the insides of the ebrake ass'y was a solid rusted mess...

The back plate which has the stone shield for the disk was a crumbling mess.

There was NO adjusting hole on the back of the old "back plate" to loosen the "self adjuster". I ended up having to use two crow bars to pry the disk/drum ass'y off.
The shoes remained attached to the drum. I was able to "gut" the ebrake and get the car home. I'm now in the process of re-assembling the ebrake.

The new back plate LH (58251-38000) retails for $119 but was able to get it for $84 from a friend that works at a KIA dealership. You can get the rest of the parts from rockauto.com for pretty decent costs.
The new back plate also does NOT have an adjustment hole.
The hub ass'y is bolted to the rear axle with 4 bolts. They come in from behind the back plate and thread into the hub ass'y.

Before you take the ebrakes apart TAKE PICTURES as the hmaservice tech site is totally worthless when it comes to info on the ebrakes.. I checked the kiatechinfo.com tech site (04 Optima) and it also lacks info.

If any of you find any pictures of the parts layout I would appreciate you posting them here.
