My wife and I have experienced rear brake master cylinder (hand lever) failures. Angela's XT (8000) twice in about 3000km where the cylinder weeps and needed bleeding regularly.
As they cannot be overhauled or serviced, they have been replaced at huge expense.
My 8100 XT have not even done a 1000km, and there's sign of leakage from the same place.
As a comparison, my 2006 Anthem's XT brake set are still fully functional, and have never given a day's trouble.
Anyone else?
