Hello, so there has been a few threads recently of stuck brake calipers so I decided to rebuild a rear caliper and do a write up on what you will find.
Thanks to @Exitus04 for the caliper to work on.

Rear brake caliper rebuild.
Special tools needed:
brake cube
https://www.amazon.com/OTC-4589-Drive-Brake-Piston/dp/B0050SGQVY
ball joint seperator
3/4" Forged Ball Joint Separator
Note: tool will not be used as directed
long nose angled snap ring plyers

Step 1: use the brake cube to rotate the brake piston out. the groves on the piston will match one of the faces of the brake cube. just rotate it all the way out. it unscrews. BE SURE NOT TO DAMAGE THE BOOT! there is a clip holding the outside dust boot into the caliper.
Pic of the clip in the boot:
set the piston aside with the dust boot.
GENTLY USE A NON MARING TOOL TO REMOVE THE SQUARE CUT SEAL!!!! DO NOT USE A SCREWDRIVER LIKE THIS PICTURE!! I didnt capture a picture of the seal so i got one off the internet.
here is the piston completely dissasembed. YOU DO NOT HAVE TO TAKE THE PISTON APPART ANY FARTHER. I did this just for demostration.
Now you will have to deal with the c-clip. your going to have to take the clip out.
now this picture below shows the assembly your trying to take out.
The assembly is deep inside the the caliper as you can see in this picture its pretty deep. this is an after picture after removing the clip and top hat,spring and post as seen above.
you cna use the angled snap right plyers to take the snap ring out. put a rag over the opening to make sure it doenst go shooting off. once you take the snap ring out you will have those parts come out as well with a washer and a roller bearing.
Now you can take the nut off the back of the caliper. once you take the nut off you will want to take a marker and index the bracket to the stud. it will make reassemby easier. as you can see in the next picture the stud has groves on it, the bracket that the e-brake cable pulls on also is splined. once you mark the spline and the bracket so that it goes back on the same splines grab your hammer and give the stud a smack. the following is what comes out.
make sure you also get the o ring on the stud too, it may still be in the caliper.
