I have had ZERO, NILCH, NADA, NO problems with my Grimeca System 8's
they stop awesome, they have good power, and look nice to boot.
they come with braided lines, and are easy to bleed and fill.
use DOT 3 or 4 fluid, and use the same pads as Shimano XT so no worries about having to find a place to import Grimeca pads from Italy
