Will this work ??

The seals are in the other half of the caliper.
A word of caution: Don't lose those two square rings. They don't come with the kits, and they are hard to find.
Shop the vendors for price on the kits. There used to be a seller on eBay that had them, but I don't see a current listing. There is one eBay listing for the kit and pistons, but you shouldn't need the pistons. Seal kits (for two calipers) should run ~ $55.
