4 piston calipers, reman or to rebuild?

Rebuilding the 4-pot calipers is easy to do, and works well only if there's no pitting or corrosion in the bores or pistons. FWIW, the caliper rebuild kit from Mazda contains only the seals/soft parts, and costs something like $20~40. What I would do before buying anything is tear down your junkyard calipers first; if there's ANY pitting or corrosion in the bores & pistons, or it just looks questionable, then use them as cores and purchase reman calipers. Like Ted said, those junkyard parts could have been sitting out there for years and are most likely trashed. If nothing else, tearing down the junkyard calipers for inspection before shipping them out as cores will help you learn how they are put together for a minimal investment in time.
