My cats breath smells like cat food.

Neither of those two things has anything to do with the Cleg brakes and what they may or may not use.

It looks like they can use XT pads, but what about other stuff? If you blow a line or some hardware/seals, can you use Hayes/Shimano/Hope/Avid/Magura stuff in a pinch, or are you stuck waiting on small parts from a very small company in Germany to be shipped over?

For that kind of money for brakes, I'd better be getting some spare hardware and hoses to go with them, especially if ordering from overseas. At least they use some standard forms of DOT fluid. I'll stick with some standard available stuff, that I can get parts for much quicker if I need.
