[Answer] Tech A says that when a rotor is machined an equal amount of material must always be removed from both sides. Tech B says that the minimum thickness dimension cast into the rotor is the dimension that the rotor can be machined to. Who is right?A. Tech AB. Tech BC. BothD. Neither

Answer: D. The minimum thickness dimension cast into the rotor is usually the discard dimension. The rotor should not be machined closer than 0.0310-in. to this dimension in order to allow for wear. When machining a rotor you do not have to remove an equal amount of material from both sides if the vehicle has floating or sliding calipers. However on fixed calipers an equal amount must be machined from both sides.
