I've had both of mine completely apart to rebuild 'em. /forums/images/graemlins/cool.gif Don't worry about the jack screw too much. Take the lever off of the jack screw and remove the screw from the bore. Now turn the piston so that it is open-side-up and insert the screw into the piston. Next, hold the caliper so that the piston bore is facing down and insert the piston from the bottom. You can use a big C-clamp to get it started. But don't go too far with the clamp, as part of it will be covering the hole where the jackscrew comes out. /forums/images/graemlins/shocked.gif
Once the piston has started into the bore, remove the C-clamp and insert a 3/4-inch (or so) socket between the caliper and the clamp, so that the open part of the socket faces the hole where the jackscrew will be coming through. Now continue pressing the piston into the bore until it is fully seated. The end of the jackscrew will come through the hole in the caliper and then you can reinstall the e-brake lever arm. /forums/images/graemlins/thumb.gif
