    How do you push the piston in on the eldorado caliper. Do you screw in the piston, if so which way? do you use a 9/16 wrench on the stud sticking out? I dunno, but now I get to get one warrantied at autozone, the stupid thing is leaking at the parking brake bolt.

    There is a tool used for screwing the piston back in. I find it easier to remove the e-brake bracket and then you can gently compress the piston back in. Having the bracket removed allows the e-brake shaft to rotate freely so the piston can be retracted.

    In my experience, it's not the one carried by most parts stores for disk brake service. I've tried rotating the piston and it was a PITA.

    You have the ones with the Seville-style bracket on the caliper, right? I've just unbolted the lever when pushing the piston back in.

    A big c-clamp has always worked for me. You can also try prying it in with a prybar /big screwdriver. Just make sure your master cylinder isn't full when you do it or it will overflow. :)

    That won't damage it?

    it needs to be turned back in, you will damage it by pushing/forcing it in...

    I have always just used some big channel lock pliers, grab the lip of the pistin, and turn it, it goes in.

    Hmm, maybe it turned as I was compressing it on it's own. I guess I should check if there's any damage, but it seems to be working ok.
