OK-I have the rear calipers off the car, I have them separated, and I am trying to rebuild the damn things. How in the hell do I get the piston's out? I have tried air, I have tried pliers, I am running out of ideas. The one I am working on was frozen (hence the rebuild). I can get the piston to move about 1/8 inch by beating it back in with a 3# shop hammer then prying back the e-brake lever in my vise. That is all the movement I can get out of it. Any ideas?

You should be able to remove them, one at a time, by using the adjustment screws. Use a 4mm (4.5mm?) allen wrench to back them out.

Thanks, I'll give it a try!
