So my mini has a set of braided brake lines that are around 10 years old, they are not leaking but as they are covered in the stainless braid you can't see if they are cracked or perished as you can with standard brake lines, so do these have a age limit ? Cheers

No age limit AFAIK. For info, MOT testers are now failing the old-style braided hoses if they notice them (the ones with screw-on pipe ends, as they can't tell if they have been DIY made/modified), the newer style with crimped ends are ok.

never heard of a limit , but can comfirm ive had one fail
thats the downside to them , a rubber one will show some perishing and maybe even a buldge before it fails giving you a chance to spot it and replace it

It has always been a fail to use self build braided brake fittings, but not many MOT places tend to notice,

More nonsense . Nothing in the manual about compression fitting ends on braided hoses being any different than rubber covered ones .

Fair point, I was told by my local Goodridge dealer / supplier ( who I trust and have used for many years) that crimped ends are ok as they can only be done by the manufcacturer or trained dealer, so you know the quality is good. He explained that the problem with screw-end hoses is that it's impossible to tell if they've been made or modified by untrained/diy/idiot types, so there's no guarantee it's up to any kind of standard. Not what you want on a braking system Are there any MOT testers in the house who can comment? I checked the MOT guide, the bit below might (or might not) be relevant www.motinfo.gov.uk/htdocs/m4s03000601.htm

I run a test station and the part that people get confused relates to repairs not complete hoses . Using a compression fitting on a brake pipe is not allowed but a diy hose has a little nob that slides up inside the liner to support it as the nut pulls down and crushes the olive . . As you can't see how they have been put together you can't fail them as long as they don't leak and satisfy the requirements

its called an olive and a barb.
I'm not sure of the wording or if its in the c&u stuff rather than mot, but a swaged fitting I was led to believe was legal, however many don't know about it.

A brake hose that has obviously been repaired using (as worded in the manual) "Compression joints of a type using separate ferrules" would fail as there is a specific reason for rejection (RFR) relating to it. Braided hoses that aren't leaking/twisted/fouling etc can't be failed just because the tester thinks they may have been assembled by a cak handed womble. It's all about the vehicle reaching the minimum standards required to pass the MOT on the day (or indeed in the hour-long slot) that it is being tested. If a tester is in any doubt, they will pass and advise (to cover their backside mainly, but to also keep the vehicle presenter informed of any possible future issues). In the past, testers were told, if in doubt - fail. Now the mantra is, if in doubt - pass & advise. Non testers, and the less mechanically minded would be surprised and probably a bit shocked as to exactly how bugg*red something has to actually be to fail a test nowadays! Hope this helps (I've been an MOT tester/QC for years) Edit: This is useful to read through. Start off in the left (information) column, then read the middle (method of inspection) column, then finally the right (reason for rejection), this is pretty much the process we use and unless it's there in black and white as a RFR then it's pass and advise. Although quite a lot is left to the tester's discretion, things like the brake hose in question, aren't.

Never had an issue with any of the socket olive lines that I have supplied or fitted over the years
