partner. you are making it too difficult. the calipers should not be split unless leaking. they come off as a unit. personally i wouldnt remove a caliper to clean anything unless i needed to change a rotor or actually replace or rebuild the caliper. kits for the o rings you need are available for cheap. or you can use the rebuilt units you mention although i cant speak for them.
