I have had 2 front MK3 master cylinders rebuilt with the reduced diameter piston. There seems to be little or no options except to rebuild the original. There is a problem now with too much lever travel with the lever now needing to travel further to push the same amount of fluid. The brake lever ends up just short of the grip and if the rubber line expands under the increased pressure, you've got problems. My solution was to have a braided steel line made up at the local brake supply house (the benefits of living in a city) and then I made a spacer plate from 1/4" aluminum plate to fit between the MC and the throttle/switch cluster. It works great with the added benefit that with a small bit of mill work it is now possible to access the inner mounting screw for the throttle which makes it a lot easier to remove or adjust the throttle/MC.
