How To Splice a Brake Line Using a Double Flare Union

Demonstrating how to make a double flare connection on 3/16" brake lines. This method can be used to splice the brake line in order to eliminate a corroded section.
I used an inexpensive OTC 4503 Stinger Double Flaring Tool Kit that I purchased from Amazon to make the flare connection.

Been doing electrical and welding for some time now, and wow. I always thought that brake and steel fuel lines were voodoo. Nice video. Very well explained.

Very good, and safe video! I'm 69 years old and have used this tool many times (
wrongly ) I must add. I never had that small black tool for the double flaring. It's so much better doing it this way! My way worked, but this is much better and a clean looking job.

Great video Ben! Your patient and thorough explanation gave me the confidence to tackle my busted brake line this morning.

Good job with the commentary as well as the video. Just did a couple of "practice" flares tonight in anticipation of the real thing one of these days. This really helped. 

Thanks

Nice job. Flare looks good to me . I've tried over 50 flares in the last week, on 1/4 " ni-cop, never came close to what he did . Looks like a good chamfered end is a critical step as part of the prep .

Your video has changed me from steel to nickle. Very good video. Thanks

Benjamin, great video, very complete and timely ... I just had to cut off my old brake line and didn't want to have to replace the entire steel line from the Master Cylinder to my wheel. I'm hoping I have enough room to flare the steel tubing so that I can put in the splice.

Great Video, Thanks for the Flare Tool Explanation and disapproval of compression fittings for Brake lines. I would feel confident riding on this type of repair.

Nicely done video. This will help in fabricating custom brass oil lines on my motorcycle.

Thanks Benjamin. About to do my lines now; but they are metal and one is installed on the vehicle. I think it will be a bit more difficult!  Great video though.

Hi Ben, loved the video. I have a 2000 Grand Prix with a rusted area I need to replace. This gave me the information I need to get going on a fix so thank you!!

[matthewknight]

Thanks for that Ben. I bought cheap flare tool at Canadian tire(same as yours) with instructions not included. It was still 28$+ 13%tax made in China of course, and they too cheap to put a piece of paper with instructions in it. Glad you put your vid up it was very helpful.

Best video I have seem on this subject. Your detailed explanation were very helpful. Thanks for making the video.

Thanks, this was really helpful, I had never done this so of course the first ones I had to do it with were the spiral ones that come out of the ABS unit on the S-10. But I got it done. The crazy thing is I replaced one 1/4 line with 3/16 and it was fine and didn't leak. Very happy I got copper nickel because I was able to bend by hand without kinking and they flare easily too and won't rust. I even reused the fittings, you can reuse them if the threads and sealing surface is good, light surface rust makes no difference. I also second the idea that your tubing cutter needs to be sharp and the cut straight.

Good job w/ the video and commentary ... I have spliced my share of lines before but, the refresher definitely helped, thanks ...

[DatamedicsRecovery]

Thanks for this. My car just failed inspection due to a couple compression fittings (which have worked fine for years). So now I've got to go replace them within 30 or my registration gets dropped.

Excellent video and the commentary was superb!

Good job and nice close up video shots, I have never done a brake pipe before, but! thanks to your video I am about to give it a go.
