OK Mike. I can now better interpret your concern, and the consequence of renewing the flexible hoses - which will result in the ends of the metal brake pipes being ‘destroyed’ by trying to separate the two.
Not meaning to cause offence, but it’s clear to me that you are not going to rest easy until you have renewed these serviceable hoses, so really, the general opinion of the forum is not what you want to hear - and that’s OK too.
I fear it’s not going to be any consolation to your way of thinking, but in 60 years of motoring, I’ve never experienced an unexpected and catastrophic failure of what appears to be a serviceable brake hose, following normal inspection at service intervals, but I might have been lucky -? You say, these could fail at some point, even when abroad, but why not be positive, and think they won’t - following your normal inspection. Sods Law will point to component B subsequently failing when you are worrying about the potential of component A failing!
Again, with my negative hat on now, this could turn into one of those jobs where you wished you had left well alone! I really hope it doesn’t, but…
Apologies Mike, but I don’t feel I can offer any more meaningful advice with this.
Kind regards,
Gareth.
p.s. If you are minded to still go ahead with this - and I’m sure you are - is it worth getting a fine intense heat source and heating the hose to pipe connection in the hope that may help free the two from one another? Nothing lost if you still have to replace the metal pipe as well as the flexible.
