You should be able to break them down in about 15-20 minutes each, the way I do mine is remove the cross over tube let them drain over night and then stick a piece of wood between the pistons and use compressed air to blow the pistons outta each side an don’t put your fingers in there it hurts. An if the pistons don’t come completely out use a pair channel locks and just rotate them back an fourth till they come out. Remove inner seals, clean everything real good, freeze pistons overnight, lube and install new inner seals, put dust boots on pistons and slide them into the caliper, an then press dust boots into groove. If your calipers are looking pretty raggedy this is a time to have them either repainted or coated to either match/contrast the car (disassembled of course). When I’ve rebuilt mine I bought new bleeders and bleeder caps as well. When I redo them next time I think I’ll get the Wilwood bleeder kit
