I have found that just replacing rotors unless tons of unusual wear i can get away with doing it every other time. However i run a small operation and do not pull near the weight and equipment that you guys do so i imagine that you are in a different boat then me. However i can still pull everything off get it re machined and put back together in a lot cheaper then 600$ even if i pay myself my hourly rate of 40$ an hour i work to reach.
