In answer to a bunch of the statements below...not everyone has the money to run out and buy new brake lines. Or maybe you need to get your vehicle back up and running quickly until you have time to do the whole replacement. Thats my situation. No time. I need my brakes to work NOW to get to work! New brake line kits are ordered and on the way. Until I have the time to do the job, they will sit in the box.

Keep the inside of your lines clean after cutting and de-burring the ends so metal shavings don't remain. Any contaminates left inside the lines can prove fatal to any brake system in no time. Debris may jam the piston or quickly destroy the seals and o-rings. If lines are still on the vehicle, you can carefully twist a Q-tip inside both ends while to capture debris. Don't worry about leaving a piece of Q-tip hair behind, it's less detrimental that metal shaving floating around in your system. IF the lines are off the vehicle, blow/flush the lines out well. If you flush the lines with water, blow them out. Cleanliness is more important that anything. Keep the system sterile.

A person should use brake fluid to lubricate the die and the line. because other lubricants are often not compatible with brake fluid. and can contaminate the fluid in the system.

Compression fittings on brake lines are actually not legal in some parts of the world.

Why the automotive industry does not offer an inverted double flare coupling is beyond me. You know that many a mechanic has been faces with a broken brake line. I do not see why a bite-type compression coupling made specifically for steel line would be unsafe. I am a designer who has done industrial piping and specify compression fillings made by Park-Hannifin and Swagelok for steel tubing applications. Many years ago, I was faced with repairing a broken brake line and ended up having to make up an entire line that took many twists and turns. It was stressful because if I messed up the double flare on either end, the entire line was scrap and I had to start all over again. So I practiced making double flares on scrap until I got it down to a science.

I've watched a number of videos on repairing brake lines now, and yours is the only one I finished. Outstanding! Now I'm ready to fix my brakes. Thank you!

My parts store treated me like a criminal when I asked for a union fitting and told me they only have compression fittings and thats all I should be using.

A great tutorial on brake line repair, I have been doing auto repair in New England for almost 50 years so have lots of experience with rusty brake lines. I would like to add use the copper/nichol brake tubing for replacement as it doesn't rust, is easier to cut and flare and very easy to bend by hand. I by it by the 25' roll so replace whole line instead or patching sections.

Nickel-Copper (NiCop) brake lines. Best stuff ever. Bend by hand, no kinks, double flares beautifully. More expensive but eliminates all frustration. Worth it.

watched a lot of videos on here as a novice,yours is the only 1 that shows how the copper union works,i was thinking it worked another way!,thanks again.

I have owned severl older vehicles with steel brake lines and live in the salt belt. Over the years, I learned that you should always have ample brake line parts (e.g. brake lines, fittings and tools) on hand at all times. Also, replace as much of the leaky brake line(s) as possible when doing a brake line job. Take it from someone who has done dozens of brake line repair jobs over the past 50 years.

Flares are better than compression rings. Always. Once you have the tool, it's just a matter of discipline to do the flares and that pays off after the first repair. Thanks for showing this so clearly!!

This is just the information I needed to tackle my burst brake line at my front passenger side of my Dakota. Appreciate the clear close-ups on the flaring details such as setting the line height in the anvil part the same as the thickest part of the die. thanks again.

Glad to see someone using the proper procedure for brake lines . I've had many arguments with people that have no idea what their doing using single flare, especially with aluminum lines used on small aircraft

Thank you so much for this. This made it super easy to understand the steps and proper way to fix a small section. I’m going to do this since the previous owner used a compression fitting, and like you said, when jamming the brakes hard, it made it leak. Appreciate your time in making this video!

This is exactly what I was looking for, thank you! My old truck is rusted from stem to stern underneath, and I blew a brake line bleeding the brakes after installing new pads, rotors and calipers. For $75 I got a full set of pre-bent brake lines, but some of them are too long, or bent in such a way you'd have to take out the gas tank, take out the radiator, remove front end parts- take the body off the frame almost to get these pre-bent lines in where I need them. Instead, I can cut the really oddly shaped ones in 2 pieces, slide them in from both ends and splice them in the middle. I don't want to use compression fittings for the reasons mentioned in the video, so yeah- this is exactly the tutorial I was looking for. Thanks!

Thanks so much for an excellent tutorial video. I watched the video 3 times so I could remember the exact steps. It's not so complicated now after watching your video. Thumbs up!

Good video, you answered all my questions , I have a old truck and lost a line. Neighbor let me use his flare kit , had no idea how to use it. Plus the fact that you mentioned not to use compression fittings , which I use at work all the time . So Thank you for the video

excellent explanation of the topic at hand, including last but not least the critical distinctions between the two couplers... thank you for explaining these things and posting this video
