Well I religiously waxoil the brake pipes and unions yearly on the daily hacks, only in the last few years have I had that message, likes it's in a drop down menu.

Agreed it’s a drop down menu approach, but the terminology is too ambiguous. And in my opinion not really fit for purpose. (Brake pipe corroded, covered in grease or other material) If the brake pipes are corroded surely it should be specific. Are they really corroded, or just covered in grease, or both, I suppose if it says corroded they are corroded!

I gave the garage a ring where she had the MOT done, spoke to the tester and he said some corrosion but very minor, nothing to worry about at all, and don’t waste money replacing the pipes. He told me he wire brushed them and then he greased them !. So I asked him why was it recorded as an advisory, his reply was incase anything ever happened in the future and it came back on him. So it means nothing really, except it’s recorded in the MOT history and not really beneficial when it comes to re selling, is it !

Wouldn't bother me, it almost shows the previous owner looked after it, and took precautions. No different than waxoiling a chassis.

DVSA MOT manual extract:

1.1.11. Rigid brake pipes
If the metal brake pipes have surface dirt that needs to be removed before it’s possible to assess their condition, you can lightly scrape the pipe with a specialist brake pipe corrosion tool or the corrosion assessment tool ‘spade end’. It must be done with care so that any protective coating does not get damaged.

Chafing, corrosion or damage to a rigid brake pipe so that its wall thickness is reduced by 1/3 (approximately 0.25mm for typical hydraulic brake pipe) justifies rejection, although it’s accepted that this is not easy to determine. If you are not sure whether the pipe is sufficiently deteriorated to justify rejection, you should give the benefit of the doubt.

Repairs to the pressure lines of hydraulic brake systems are unacceptable unless suitable connectors are used. Compression joints of a type using separate ferrules are not suitable.

Unacceptable repairs to brake lines should be failed using RfR 1.1.21 (d)

Defect Category

(a) Brake pipe is at imminent risk of failure or fracture Dangerous


(b) Leaking brake pipe or connection:
(i) on an air brake system Major
(ii) on a hydraulic system Dangerous



(c) Brake pipe damaged or excessively corroded Major

(d) Brake pipe:
(i) inadequately clipped or supported Minor
(ii) likely to become detached or damaged Major

I remember when my mates garage was raided, this was a few years ago, they took the MOT safe, stamp and a nearly full MOT book

They must have made a fortune!
