Incidentally, I was reading a write up on the latest Honda Fireplace..blah blah more power blah blah 2 grammes lighter etc etc. It seems the latest brake calipers fitted are NON rebuildable...so if one of the six pistons sticks or seals leak due to the glorious British weather,you have to buy a new caliper 
...however they are several grammes lighter than the old ones apparently.....
Well I don't know where they got that from. I just looked on the parts list for the 08 and guess what, pistons and seals listed as usual. Just remember, never believe everything you read. I do believe it may be true of certain Honda cars though, I'm sure I came across one like that a few months back, can't remember which model though.
Makes slightly more sense for a car's rear were the hand brake is electric a la VW. The launch control requires fairly close set up to avoid roll back and this can be a PITA even with the vehicle diagnostics. If the one calliper includes the electrical/mechanical hand brake and hydraulic footbrake it does become a big complex lump that might be better (safer) reworked at the factory. I'd expect an exchange set up on something like this to be not that much more cost or hassle as the worldwide volumes will make sense. Imagine the wait while say Ducati rebuilt your brake and sent it back though
