Well crap, now I find out after doing complete front and rear master cylinder and caliper rebuilds...guess I'll see how long they hold up.K&L has been around a looong time - long before Mike started importing stuff via Taiwan (in fact IIRC Mike Lalonde used to work for K&L before he went off on his own). K&L's products have always been good quality; I can't remember anything that was substandard or unservicable off-hand.
Oh well, at least I'm cheap labor...
