MOT advisory “Park brake mechanism/associated mountings prescribed area is corroded but not considered excessive” — meaning and what to do
Last updated · OBDCode UK editorial
In plain English: the tester noted a brakes item that was not a fail on that MOT. Act now.
Can you drive with this?
Limit driving. Limit driving to short essential trips until a garage has assessed it. Avoid hard loads, towing, and long motorway runs.
Vehicle support. Never go under a car held only by a jack. Use axle stands on the handbook support points, on firm level ground, with wheel chocks. No roadside or slopes. Rock-test before you go under.
What the tester saw
MOT testers work from the DVSA inspection manual. For this item the manual wording is “The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area) is significantly reduced ”. In plain English: the tester judged that wear or deterioration on the park brake mechanism/associated mountings had not gone far enough to reject at that test. That is why it was recorded as an advisory rather than a failure. It is not a statement about the vehicle’s condition or legal status today.
If it worsens to the manual fail wording above, DVSA would class that defect as Major. That grade describes the fail threshold, not the recorded advisory.
Do you need to fix it?
An advisory did not affect that test’s result. It is the tester telling you what is likely to need attention, and how soon depends on the item.
- Act now. Do not plan around waiting for the next MOT. Get a professional assessment promptly; some items mean you should limit or stop driving.
- Can you DIY? We do not publish DIY repair or strip-down steps for this advisory. External look-over only; leave structural, brake hydraulic, fuel, steering, or restraint work to a qualified garage.
- Buying a used car? Repeated advisories for the same item across several years of MOT history mean the owner has been ignoring it. Check the car’s full record with our free MOT history check.
