Hey guys I'm writing this up to help with those of you who may need to service your rear brake calipers, but don't want to spend the money on replacing the whole caliper. I did this because I noticed that my inboard pad on my drivers rear was wearing faster than the outside. Also found that the piston would not retract back into the caliper. So this is my write up for a complete rear brake service (pads/rotors/caliper cleaning).

Tools I used:
3/8" Ratchet
11mm Deep Socket
13mm Socket
7mm Allen head Socket
5/8" Wrench
Pry Bar
Needle nose Pliers
Nylon and Brass Brushes
Piston Reset Tool

Obviously you want to jack up the rear of the car and remove the wheel you are going to be working on. It is always a good idea if you are working on the ground to use a jack stand (SAFETY FIRST). I, fortunately, have the use of a lift.



Using the prybar pry back on the e-brake bracket and use the needle nose pliers to feed the cable free from the bracket. Then remove the clip holding the cable to the bracket and position aside.



Remove the rear caliper using the 13mm and 5/8 wrench (I used a 5/8 because it was the only thin wrench I had in that size)



Use the 13mm socket to remove the brake line bolt. Fluid will come out, I used a plastic cap that fit perfectly to keep from losing excess fluid. *If you are not going to take apart the caliper skip this step.*



At this point you can remove the brake pads. Use the 7mm allen head to remove the caliper bracket bolts and remove the caliper bracket.



Now you can remove the rotor. If all you are doing is replacing pads and rotors you can start re-assembly in reverse order. Caliper piston reset to follow later.

Now that you have the caliper off the car, using the caliper reset tool unscrew the piston all the way out (I had to wiggle it out the last 1mm or so). Inspect the caliper bore, piston, boot, and bore seal. If the seal is torn I strongly recommend replacing as it will most likely leak.




Next I used some brake cleaner and the brass and nylon brushes to clean the gunk off the piston and caliper bore. As well as a right angled pick to clean out the gunk from where the boot goes into the caliper.




I then used compressed air and blow gun to blow out all debris from the caliper. While I had the calipers out I decided to clean them up and give them some paint.



Now it's time to start putting it back together. Slide the boot out of the front groove towards the back of the piston. Insert boot into groove in caliper first (I forgot to do this and had to take it back apart to get it to seat right, lol). Then by hand push piston into caliper and start to thread it on by hand. Once started use piston reset tool to fully seat piston in caliper. Should look like this.



Now you can reinstall brake rotor, caliper bracket, brake pads. Re-attach brake line to caliper (make sure you have a copper sealing ring on either side of line. Bolt caliper back on to bracket, and reattach e-brake cable to caliper.



Fairly simple and straightforward job. Remember to take your time and you should be all right. Remember this is a guide for what I did and how I did it. I am not liable if you follow this and mess something up.

Now you can remove the rotor.
