    I know it was discussed by Shawn a long time ago but I can't remember if was here or on the OR BB. Either way; did/does anyone know how to get the piston on the 78 Caddy Caliper to retract once it's been ratcheted out?? It's not the end of the world for me cause I did it on the old set I have to use for cores while I was stripping them down BUT; it'd sure be nice to know in case I accidentally mess up a new one!![​IMG][​IMG]

    Thanks

    The easiest way that I've found is to remove the nut that holds the parking brake lever onto the screw mechanism at the backside of the caliper. Then as you press the piston back into the caliper, the screw can spin as it returns to its home position.

    BTW, don't even think about taking the piston itself apart. The mechanism inside the piston has a hefty spring inside, along with some ball bearings that ride on two Torrington style races. Putting it all back together without breaking the races is pretty tricky. Guess how I found out? [​IMG]

    The Cadillac dealers can't get parts for the inside of the piston. They only sell the entire caliper assembly. Luckily I was able to take the measurements of the Torrington races to a shop that specialized in bearings and get the new one that fit. [​IMG]

    I haven't looked at mine for a couple years, but can't you just screw it back in?

    Thanks Harry & Pete

    I'll give that a try Harry & unfortunately Pete; mine are in that bad shape that very little "just screw in" on them anymore!![​IMG][​IMG]

    Thanks again

    You can literally "screw" the piston back into its bore also. There are some notches in the face of the piston that accept a special spanner tool for doing exactly that. Since I had mine so far apart when I rebuilt them, I used the method I mentioned above. [​IMG]
