MOT defects: Master cylinder/servo mounting
Brakes
8 defects: 4 dangerous, 4 major. 3 can be given as an advisory instead.
| Certificate wording | Severity | As an advisory | Inspection manual |
|---|---|---|---|
| Master cylinder/servo mounting prescribed area is excessively corroded and functionality of the braking system is affected | dangerous | None | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is so weakened that the functionality of the braking system is affected |
| Master cylinder/servo mounting prescribed area is excessively damaged and functionality of the braking system is affected | dangerous | None | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is so weakened that the functionality of the braking system is affected |
| Master cylinder/servo mounting prescribed area is fractured and functionality of the braking system is affected | dangerous | None | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is so weakened that the functionality of the braking system is affected |
| Master cylinder/servo mounting prescribed area is inadequately repaired and functionality of the braking system is affected | dangerous | None | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is so weakened that the functionality of the braking system is affected |
| Master cylinder/servo mounting prescribed area is excessively corroded | major | prescribed area is corroded but not considered excessive | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is significantly reduced |
| Master cylinder/servo mounting prescribed area is excessively damaged | major | prescribed area is damaged but not considered excessive | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is significantly reduced |
| Master cylinder/servo mounting prescribed area is fractured | major | None | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is significantly reduced |
| Master cylinder/servo mounting prescribed area is inadequately repaired | major | repair covered in underseal | The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is significantly reduced |
