My two Combat came with the brake cable routed under the Z-Plate so the cable bore on the edge until it wore a obquie groove the area that tough to eliminate w/o grinding about 1/4" of Al off the surrounds. Point being the factory way is not that good but the way the factory has the lever and muffer mounts set up there just ain't a really good way and it indeed hints the brake effectiveness somewhat too. Even the after market rear sets, if installed as designed, require the same poor routing. If ya put the brake plate stop peg under the swing arm edge instead of in its slot, so it let the brake cam lever lean back a ways, and the rear set mount cocked CCW one bolt hole alignment amount, then you can get a direct straight shoot at the brake lever w/o any collisions nor cable wear nor lost lever effort.
