If you realy need to replace them, somebody posted a link to e-bay, with a full kit of everything you need to refurb your Tokicos, for a lot less than my stealer wanted for just seals. I'll see if I can find it.
Last time I stripped a troublesome caliper, I hooked up the master cylinder directly to the caliper, bled it, then pumped out the piston with that. Worked a treat, if a little time consuming to set up. I have a small block of wood about 15mm thick that I put between the pistons, then I can just pump out until all six pistons are in contact with it. If you're going to split the caliper halves I'd suggest loosening the four joining bolts slightly whilst the calipers are still in situ on the bike. The fork legs make a pretty useful caliper counter-holding tool
I used one of these seal kits for the last few years:
And had no trouble with them. My preferred Suzuki dealer also now stocks the same brand of pattern seals.
