It depends on how far the rebuild goes. If its just piston seals and dust 
caps, yes all you need is a retractor, but if the whole caliper is being 
stripped, self adjuster, handbrake and all, then some sort of special tool is 
needed to compress the self adjuster spring to allow the circlip to be fitted 
during reassembly. Even this is nothing complicated, I made one from a cycle 
bearing puller and a metal sleeve. 

Rocket science, Phil? Isn't that a bit low-tech for a man who powers his 
lights with dilithium crystals? :-)
