| Summary of Issue | An actively leaking inner wheel seal on a disc brake system but it does not contaminate the brake friction surface due to the oil draining in the rotor vents. See attached video. |
| Justification or Need | The active wheel seal leak poses a safety risk due to losing all of the oil and the hub seizing up, which can lead to a crash. Furthermore, it is likely at some point the brake friction material will become contaminated during transportation, which could lead to a fire, as well as a defective brake. |
| Request for Action | I respectfully request the Out of Service Criteria be amended to include wording which places a vehicle out of service if a wheel seal can be seen actively dripping without the brake friction material being contaminated. |
