I am sick and tired of destroying brake lines and fittings every time I go to work on brakes. I am always rounding off the fittings (which are WAY too soft IMO) and usually ruin the fittings and lines in the process.
Would there be any ill effects to using some anti sieze on the threads of the flare nuts on the connections?
It took two pipe wrenches to break apart three fittings today and one line i had to cut. This is probably going to cost me God only knows how much to fix. The small 3/16" line from the rear brake splitter to the left wheel cylinder wont be too bad, but since i ruined the big line that runs from a joint just in front of the gas tank to the block in the back on the axle, it could cost me quite a bit if a new line needs to be made.

I can't remember but I think I was told once if the pipe uses the treads to seal then its ok to use gasket pipe tape. But if you use tape on a pipe with a o ring it will leak. Not saying use tape but I don't see a problem with anti seize. But also I never had a problem with flare nuts as long as I use a flare nut wrench. And if the pipe did break some how it was probably about time to replace it anyway

Did you use flare nut wrenches? You probably did, but just making sure.

ive used a little bit of antisieze on the threads and a little bit between the line and the nut so they dont rust together

Just Replaced All The Brake Lines On My 1984 C-10, Used a little dab of Antisieze on all the fittings with no leaks.

I have use never seize on the lines and thread of brake line fittings before. Never had a problem. We use it on them, on hydraulic pipe, & hose threads, fuel lines etc. all the time at the shop. The only time we use pipe sealant dope is on pipe threaded fittings.

I use anti-sieze on line fittings also. Never had a problem.
