brake lines rusted
I recently replaced the rear brake shoes (and e-brake cable) on my 87 bII and I had bought the wheel cylinders to replace while I was at it, BUT upon inspecting where the line goes into the cylinder I discovered that it is rusted so badly that the threads REFUSE to break loose. Does anyone have any suggestions as to how I might get it loose (leverage is not a problem, but being restricted to the open end of a wrench I know that it will simply round off the fitting -- I know this because I already tried it and the wrench would only slip and round instead of grip and loosen)? I applied an extremely good penatrative lubricant VERY liberally and let it sit before I even attempted to break it loose, but it is just TOO rusted! I am not looking forward to buying new lines because the fittings on the other end are prolly just as bad and therefor I will have to have ALL new hardware for essentially my entire brake system. Anyway, I suppose I will do what I have to do, but if anyone has any suggestions they would be GREATLY appreciated.

Hey bronco 2 you need to find a flare wrench that size and use it also most of that penetrant on the market has to be sprayed on and then soaked overnite to have any chance of working. I find that the line itself will rust to the nut so if you do get the nut to break loose the line will be rusted to the nut. If you have access to a cutting torch you could use some heat on the nut and use a rocking motion with the flare wrench back and forth to try and break it loose. If you have to replace those lines they are not that exspensive.
If their that rusty i would question the rest of the line

Hey bronco ll sorry it took so long to reply a flare wrench actually looks like a 6 point box end wrench with a slot cut in it toallow the line to slip thru and still have all six points of the nut in contact with the wrench its made for that purpose hope that helps

Long to reply? It was like 5 min later!!! *lol*
Anyway, I think that what you described is what I call a "line wrench" and that is what I was using. The wheel cylinders are not leaking yet and so I am not going to attempt this task until I have to. In the meantime I plan on soaking those fittings with penatrative oil every time I change my oil (or happen to be under there) and maybe by the time I get ready to try again it will have loosened the rust enough to perform a miricle. Thanks for your info though and if you (or anyone else) can think of anything else to try then please post that as well.
