I am having the same trouble getting the flare nut off my front brake line and I am considering getting a blowtorch as per various recommendations on this site. However, a couple of things concern me: firstly, is brake fluid flammable and if so I presume I need to drain the brake line (or even the entire system?) and secondly, is there an effective way to protect the inner wheel arch from the heat (or will the years of encrusted crud do that???). Thanks in advance.

Be careful heating up the end of the flexi hose. They go off with a heck of a bang when heated up !

In the end I cut the retaining spring which released the flexi enough to rotate the flexi out from the lock pattern cut into the holding bracket. This meant I didn't have to rotate the flare nut and the seized pipe. I made up a new large s/s washer and rotated back in the new braided flexi from an outfit on eBay (and fitted new retaining springs from Rimmers at the same time.) https://www.ebay.co.uk/itm/274286573074 Unfortunately you wouldn't be able to use the standard OEM flexi with this method since you couldn't rotate it back in due to the cutout in the bracket engaging with the gnurled lock ring on the flexi. I'm sure others more experienced than me will come along with advice and correct me if I got anything wrong, but so far my brakes seem fine, and all is well. Good luck. Just take your time to get it right, 'cos getting it wrong with brakes is not an option we want to explore. I did all this as I wasn't confident about using a brake flare tool and replacing the hard brake lines. Next time though I'd probably go for convention since making up the s/s washers took me probably just as long as getting used to working with a brake flaring tool! |

Only use heat as a last resort. If the fitting is seized then cut the solid pipe above it, hammer a surface drive socket on and it should shift - never failed for me.

Thanks for that. In agreement with Marinabrian's post. Useful to hear that re-inforced by another experienced member

Heat didn't work for me - the front unions were too badly rusted.
I used a Duratool D03363 mini blow torch, which is very accurate and has enough wellie, but heating these two was never going to work so I cut them off. |

Did you use a surface drive socket and give it a good few clumps with the hammer? That helps break up any rust in the threads.

No, I cut the pipes & hoses and replaced the whole lot.
