maldren said:Not sure that's actually correct, my Elan +2 has copper pipes fitted by a PO, they're very different in colour from Kunifer.
Kunifer is a silver/green colour whereas Copper is, well copper coloured like a 2p coin!

Its either a 10 or 11 mm as there is no imperial anything on Porsches and there is no 10.5 .. it should be an 11 which has corroded .
Your choices ..
Replace No.9 ..
Do a cut and join on No.9 .. i dont recomend that ..
Use mole grips on the corroded nut and either a spanner or more mole grips on the flexi pipe .. youll need to force it out of the bracket or at least far enough so it can be turned as the bracket locates the flexi pipe ... and whilst holding the metal pipe ( no.9 ) in place you will undo and twist off the flexi pipe .
Its important not to allow the metal pipe to twist .. it wants to be held ridgid as too much twist will fracture it .
Your kinda doing the job backwards basically .
You could cut the nut and re flair but if its steel pipes then i wish you the very best of luck there and if not it may well be too short to reach the pipe ... i think go down this route if my above suggestion doesnt work
Demort said:If you use mole grips then you remove the flexi from the metal pipe and refit it the same way .. it wont be pretty but then it isnt now due to the corrosion.
You could use something else rather than mole grips if you want as thats just an example. .. there are pliers out there with plastic jaws .
The best way is obviously to replace all the pipes needed but this was an unexpected failure and so a quicker repair for now is IMHO fine .
If it doesnt work then you are left with replacing no.9 .. i think reflairing might be a problem .
Lets face it if it dont leak then theres nothing wrong with it , i dont condem things because they are ugly
Anyways you got my number if you need it !
ragpicker said:I usually heat them up with a blow torch, the crud falls off them and they unseize too. Sometimes you get the brake fluid catching fire as it drips out which is always interesting.
Another favourite trick is when the flexi pipe is siezed into the calliper and you heat the calliper so much the flexi blows off and makes a sound like a gunshot.
Neither of the above are the best way to do the job by the way.... I hadn't thought of the double mole grip method
