| Summary of Issue | I would like to see a safety report on cracked rotors re: OOS at roadside inspection, the criteria for diminished rotor effectiveness, if the 20% reduced braking capacity applies, if so, then on a vented rotor, each surface would figure into the formula, you can order rotors with holes and slots cut into the wear surface that are marketed as a more heavy duty rotor. In essence a rotor with cracks machined into the wear surface. |
| Justification or Need | With the built in safety features of the rotor, why would the need of an OOS order and a tow removal to shop be required for a single crack not extending into the bowl of the rotor when an order for repair within 30 days would suffice. If the rotor and brake friction material are within minimum limits, braking capacity is not affected in braking reduction in any great amount. |
| Request for Action | I would like to see engineering report on safety features on rotors and reasons for 75% crack to be OOS, remove the OOS condition for a cracked rotor unless the crack extends into the bowl or hub of the rotor, or the crack is on both wear surfaces of the rotor. |
