MOT & brake pipes

[TheGriffalo]

Are reusable fittings an immediate MOT fail on flexible pipes? Someone said if they weren't swaged it's an MOT failure but most of the Goodrich self assembly fittings (the olive type) have a higher burst pressure than a normal pipe with a swaged fitting.

Does anyone have the definitive answer before I take a saw to mine?

Hang on, am I getting this here?

Are you talking about braided hoses? If so, then you should be fine - I've had them on just about all of my cars and MOTs in that respect have been fine.

I would go and aks at your usual MOT place.

I've got braided, that's fine. It's just that I want to shorten a couple of them and there's some confusion about making the ends off yourself with compression fittings rather than swaged ones. Some MOT places appear to have different opinions, hence me looking for the definitive answer.

I've not checked but i assume it'd be mentioned here

I am good mates with an experienced tester ( he does not do my cars as he lives in the wrong part of the country ). I could give him a call and ask him if you like. If I were you I would ask the garage where you normaly get your MOTs done what their views are. Even if the definitive answer is that its OK, if they don't like it, you don't want to have to fight to get it passed. If the definitive answer is no, but they accept it, you don't want to make extra work for yourself.

3.6.B.2.D (!) states:

D. inadequately repaired or with unsuitable joint fittings

Note: 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

However, the sub section it is stated in (B.2) is for rigid brake pipes.

I would not fail a car for those pipes, the note is there more for olive type hard line joints I believe, however different testers interpret the guide differently, I had one re-test on a car the other day that stated no warning system was fitted for low brake pressure, using the guide number for the fail (as printed on the sheet) to check the fault I found it was an air brake warning system it had failed on....DOH!

Good links there... To an inconclusive answer No wonder the testers have differing interpretations of the guidelines!

Well - that's my Xantia cream-crackered, then! The brake lines are populated with such fittings!

My personal preference would be to buy new shorter ones.
