Smart move. If you want to rebuild your original calipers, I would soak them in a good rust removal solution for at least a couple of days. If I remember right, those are metal pistons in the calipers, and they WILL take off like a bullet under a lot of air pressure. After you get the old ones out, you will need to clean the piston bores, here is where you will have the problem, if the bores are real pitted you may need to have them machined and sleeved, there are shops that can do this, but it is pricey. The good news is once done by a good shop, they will last forever, not like the junk rebuilds you get from China. Good luck.Yeah factory disc car.
took the originals apart in hopes of potentially rebuilding them. One piston in each side are frozen. Attempted to plug the holes and use air pressure to push them out. Ran the pressure up to 80PSI before I ran out of cajones. I didn't need a missile shooting across the garage.
The bores of the ones I did manage to get out are rusted pretty bad.
I would also change over to DOT 5 brake fluid to cut down on the moisture in the brake system.
