+1 for silicone grease - it's what Brembo supply with their seal kits.

When I rebuilt a couple of other calipers, with the pistons and seals came sachets of red rubber grease, working perfectly

To clarify my earlier tired answer
I would use it above the seal and in the gap arround and behind piston but i would not use it on the seal, in the seal groove or in the bore as, personaly, i would not want the chance of any contaminent in the brake fluid cos i am not a good enough chemist to know what would happen
