It's a somewhat fiddly job getting the old seals out, the dust seals are easy as they're near the edge and are thin... the inner seal is thicker and less flexible. I made up a tool from one of those big staples you find holding cardboard boxes together. To avoid scuffing the front surface of the groove that the seal sits in (which is what the seal presses against when the brake fluid is at high pressure) it's best to hook the seal out from behind. Diagram probably explains it better:

Other than that, and the usual worry of keeping the insides as clean as possible when the outside parts seem to have limitless quantities of grime and loose corrosion trying to get in there, and the hassle of bleeding the last reluctant air bubbles out once you've refitted it... yes, it's an easy job. :lol
Hope tomorrow's attempt to clean the pistons is a success!
