Brake Pipe Corroded MOT Advisory Cost and Buyer Risk
A corroded brake pipe advisory is one of the more serious MOT notes. It can become a dangerous brake fluid leak and often gets worse quickly on older UK cars.
Typical UK cost
GBP 120-350 per section, more if multiple lines need replacing
Buyer risk
Urgent repair risk
Negotiation note
Ask for evidence it has been repaired or negotiate at least GBP 200-500 on an older car.
MOT wording this covers
- Brake pipe corroded
- Brake pipe corroded, covered in grease or other material
What it means
The tester has seen corrosion on one or more metal brake lines. Light surface corrosion may be monitored, but heavy corrosion near clips, unions or bends can become a major defect.
Is it safe to drive?
Treat it as urgent if the pedal feels soft, brake fluid is low, or the advisory appears repeatedly. Do not ignore it on a car you are buying.
Should you buy a car with this advisory?
For a used car purchase, repeated brake pipe advisories are a clear negotiation point. Walk away if the seller dismisses it, the car has multiple brake corrosion notes, or there is no recent invoice for repair.
Checks at a viewing
- Check the MOT history for repeated brake pipe corrosion advisories.
- Look under the car for flaky rust on thin metal pipes, especially near clips and rear axle areas.
- Check the brake fluid level and look for damp patches under the car.
Garage checks
- Ask a garage to inspect the full brake line route, not only the visible advisory area.
- Ask whether the pipe can be cleaned/protected or needs replacement.
