But the devil is in the details, or in this case how you use the barrel adjuster. I agree completely with the danger of reducing the caliper's actuating arm's travel as that could cause the arm to bottom out before the pads get full bite on the rotor. But using the barrel adjuster to establish the fine tuning of the cable anchor WRT the arm's initial start of it's travel is, IMO, acceptable. To only rely on the cable anchor bolt and where along the cable is clamped is like using a base ball bat to swat a fly. Sure can be done but it's easy to damage stuff if you don't get it just right the first time. Andy (who is failing to come up with a better analogy that is also funny).
