It is worth mentioning that reassembly of a dual pivot caliper and getting the tension correct on the pivots can be a major PITA. Just like a hub, the goal is to get the pivots as loose enough to pivot freely while also having little to no play in them. Worry about getting the center pivot adjusted first, then do the other pivot second. Sometimes the center pivot can tighten up slightly when the caliper is mounted to the bike, so make sure it still moves ok while mounted before messing with the other pivot. Make sure to tighten the set screws once the each pivot is adjusted. Once that is done it is time to get the spring tucked into place, do it while the caliper is mounted to the bike. A flathead screwdriver can be used to push it in place, but something with a concave surface will make it easier and safer. Make sure all fingers and other body parts are not positioned in the way of the spring if it slips loose, it can easily damage any flesh it comes in contact with.

Good luck!
