I had the same problem at around 20 000kms/1 year. All advice I heard was replace the entire slave cylinder. Rebuilding doesn't work well.
I think the major cause of failure was not cleaning the chain muck out of the front sprocket area regularly enough, resulting in accelerated corrosion. (Lots of wet, salty riding conditions.)
The replacement part has lasted twice as long as the original and is showing no signs of failure (knock on wood).
For what it's worth, I was able to get it replaced under the extended 3-year warranty, though this was also a bit of a favour from the shop.
