Help removing '02 Sonata rear rotors

I need to replace the rear rotors on my 2002 Sonata V6. It has the
rear disc brakes with the internal parking brake that is like a mini
drum brake inside the rotor. The rotors will not come off because of
the parking brake shoes are contacting the inside of the rotor and, I
assume, because there is a ridge of rust as there would be with
conventional drum brakes. I removed the adjustment plug and located
the star adjuster but it (on both sides) is rusted solid and I only
managed to break the teeth off the adjuster trying to turn it to
release the shoes. I tried a puller but it only pulled the whole
parking brake assembly with the rotor and I backed off before
something broke. The diagrams and information of the HMA service site
is not very helpful for this procedure. I Would greatly appreciate
any suggestions for removing the rotors. Thanks in advance for your
help. Dave

 

Don't be afraid to use a hammer. I cannot actually recall a time where th
parking shoes actually stuck to the rotor. Usually, the rotor is ruste
onto the hub.

Of course, I'm assuming you're replacing the rotors. If not, you'll nee
a heavy plastic hammer

 

Thanks - yes I'm replacing the rotors (hopefully) but the old rotor is
free of the hub - it comes off about 1/4 inch before it gets caught up
on the parking brake shoe. I've ordered a parking brake hardware kit
and when I get it I'll try to break the adjuster free with a chiesel.
The emergency brake is dragging inside the rotor and I think it has
worn a ridge that is holding it in. This car sat most of last winter
and that probably has something to do with the problem. When I tried
to pull the rotor with a puller the hub actually came about an inch
off of the hub, but I could look behind it and see that it was pulling
all of the brake springs right off the backing plate and I didn't want
to do more damage than good by breaking something inside the rotor
then having it still stuck on.

 

I would also spray as much Liquid Wrench as possible through the brake
adjusting hole. Since you are replacing everything, you have nothing to
lose. Maybe that will free your star adjuster. Are you sure you are going
the right direction on the adjuster? They usually are different from side
to side of the car. Soak the heck out of it and let it sit for a day.
