I've watched at least 75 videos on brake lines, forming, double and bubble flares, etc. Quite a few have erroneous information. THIS video is complete and accurate, and contains information about little nuances that are found no where else. Well done!!
This is the best brake line instructional video on TH-cam. No doubt. One note: In the "rust belt states" gravel guards tend to hold road salt solutions and road silt making the lines rot very quickly. I would only use gravel guard on stainless or the copper/nickel lines. Thanks for making this video. It's a "Jim Dandy" for sure.
Jim, the video is one of the best brake line fitting break downs I’ve ever watched. You should update your video title to some how catch the attention of ALL viewers who are interested in brake lines repairs/replacements. Your title isn’t doing your knowledge sharing justice! Once again thank you for your amazing work.
Brilliantly put together and explained, so many videos out there with mistakes and incorrect terminology, this one stands out. Thanks for taking the time and trouble to produce this, you will save many people lots of grief 👍
Thank you!!! working on a 97 firebird front to back brakelines. Your video the most helpful concise and informative. I went from confused - angry - despairing to informed and enlightened. Keep up the great work !!
You were right I've been binging on breakline videos and your video was extremely informative on making the different type of flares and fittings. You give me confidence my friend. Thank you.
Jim Dandy! Thank you sir. The most comprehensive and complete brake fitting guide I've come across. Your insturcuction is beyond reproach. I've been searching the web for tutuorial just like this as I tackle, for the 1st time, a few rusted brake line junctions on a '01 4Runner. Not sure that I've ever commented on a video before but felt on the slim chance you might read this, a gracious thanks hurled your way through the digital ether might represent my gratitute. take care and keep up the good work!
As you said at the beginning, there is a lot of other footages that show how to use the tools - I'm really happy you made this video and explain what those other clips were missing.
i know Im randomly asking but does anyone know of a trick to get back into an Instagram account? I was stupid lost the login password. I would appreciate any help you can offer me
@Raiden Maurice thanks so much for your reply. I found the site through google and im trying it out atm. Looks like it's gonna take a while so I will reply here later with my results.
This is without a doubt the most comprehensive, informative, useful, thoughtful and interesting video on brake lines I've seen amonst the hundreds of other offerings on youtube. Thanks for posting. Anyone reading this; stop reading this comment and go watch the video instead
I just got done replacing about 4 feet of corroded line in my 98’ Acura Integra. Fingers crossed that this will do the trick and that I will be safe out on the road. I’ll be bleeding my lines next and then taking it out on a test run. Great video. Makes me feel confident that I did exactly what needed to be done.
Used a single flare on a hydro brake and air always gets in, I did so much research and no one else ever brought that up... Now I know how to fix my problem. Thank you.
This video should be viewed by all "do it yourselfers" who plan to replace brake lines. After I gave the make, model, and year of the vehicle I was working on, the local auto parts store sold me an inverted flare brake line instead of the bubble type I found after removing the corroded line from my vehicle. I didn't understand the difference before I viewed Jim's video, thanks Jim.
Jim Dandy to the rescue, go Jim Dany, Go Jim Dandy! This video was extremely helpful for me to determine if I was going the right route for creating my own replacement brake line for an American/Japanese mix vehicle that appears to have M10x1.0 fittings on both ends, but one having the extended tip. You covered it all.
If I'd found (well YT search had recommended) this video sooner it would have saved me a whole bunch of time getting dribs and drabs of the story from other places. Thanks for putting this all together.
man i watched this whole video and learned so much and finally solved he whole double/bubble flare , fittings, etc. Watched it a second time to subscribe and like the video and when you said I learned all this in the last... cpl days, I laughed so hard. Excellent video, as good as a professional instructional video and way cooler.
Jim you could not have explained that any better, it is obvious from seeing other videos there are a lot of people out there who do not realize there are different flares for different fittings, thank you for your very helpful video.
Very good video. I rebuilt automatic transmissions in the 1980s and I had a flare many times for automatic transmission coolant lines. At least at that time we ONLY did double flares on the transmission lines.
Very nice video, especially for learning the process in just a few days. Happy to see you commented on using the proper flaring tool, the ISO/DIN bubble cannot be made properly using the SAE tool. Close, sure, not not correct and they often will leak. Not worth the risk.
I used an SAE tool to make DIN bubble flares because I couldn't wait for the proper tool to arrive. I wouldn't try it with steel but I think its okay because I was using nicopp with steel fittings. Good video, wish I watched before I needed new brake lines!
I just had to replace a hard line on the rear of my 92 Cavalier and it used a bubble flare on the two connections that I had to take apart. Good video.
I turned my double flare jig to flat side and did only first step of double flaring, and I get the bubble flare profile and it works well.But thanks, very good information.
So can i use a bubble flare as a male and mate it with a double flared end with a female nut? Some eurocars have this as standard but i can't find a video on how to make the different ends up.
Great video! I've been researching youtube the last 2 wks and checking tools needed. My manuals don't identify which lines are brake, transmission cooler or gas lines. I haven't been able to find any good diagrams for 2003 Durango 4.7L so, I'll keep searching for that info. thanks for the video! ps. brake lines are easy to identity since they go to the brakes, same with transmission. the others... vapor/fuel lines and emissions lines I'll have to get down and dirty!
Great video! I've noticed OEM's have used a female flare nut with a male bubble nut rather than a union, this results in roughly half the chance for a leak! The female flare nuts are near impossible to find though. I agree if you need a bubble flare, definitely use the correct tool!
Two things, 1. Old Land Rovers use a bubble flare, I have a 1967 2a, and had a heck of a time finding the correct fittings and information on the flare differences. 2. several people on TH-cam have directions for making a bubble flare with a double flare kit, they recommend using the die on the flat, not the countersunk side to get the flat surface you need. But I like you, bought the bubble flare kit, so I can be sure the flares are properly made. The reason all manufactures went to the bubble flare, is it is supposed to handle higher pressure with a wider safety margin. Also ISO European and Japanese bubble flare fittings are made differently, look closely before substituting.
..I have a dragging brake piston and the steel line is corroded. I will have to replace everything. Didn't know about the single flare, double flare difference. This information is gold : )
A single flare is made by simply pushing a cone into a piece of tubing thus the wall thickness is the same as the tube wall thickness. Single flare is for low pressure line transmission lines. With a double flare you smash the tubing into a gig that rolls the tube into like a bubble, and then you push the cone into it which creates a double wall thickness. Double flare is a "must" for brakes, but some people get away with a single flare, but it's like not wearing seatbelts, it works until it doesn't and then it's bad. The bubble flare seems to be the most common now days. It requires a special gig (ISO metric bubble), but creates a double wall thickness like the double flare. You can fake a bubble flare with a standard double flare kit, but it's not the right way to do it. Double flare kits are in every autoparts store, but the bubble flare kits are harder to find. It should be the other way around now days, but .....
thank you!!! I laughed at the forgotten nut. I had a similar issue last night. Welded a clevis onto Master Cylinder rod, forgot the retaining plate. Then almost forgot the rubber boot.
Very good video, thank you! It explained one main thing I wanted to know, but wasn't able to find info on: can a double flare kit "simulate" a bubble flare if you're in a pinch. Apparently it can. That being said, I'll still buy the proper kits for both. :)

Best video on different types of flares. CHRYSTAL great job thanks for passing on the knowledge it helped me fix my C300 rusted brake lines
This is without a doubt the most comprehensive, informative, useful, thoughtful and interesting video on brake lines I've seen amonst the hundreds of other offerings on youtube. Thanks for posting. Anyone reading this; stop reading this comment and go watch the video instead
Excellent, excellent tutorial. Very complete. Really helped me and I have a lot of brake line bending and flaring experience. Thanks so much.

Execellent Instructions On The Mechanics Of Flaring. Kudos To You, You Are The Flaring King! Thanks...
Super informative video. Everything condensed nicely.
Thanks for the video. I like the reference drawings showing the standards.
The best vid so far on the subject, good for problem solving
Thanks
Nice!!! I enjoyed your well laid informative video regarding the details on brake flaring in general. Thank you sir!
Definitely should rename the video, it's very useful. Watching this one video has been more useful than watching 10+ others
Thank you for this informative video. Helpful to understand the task at hand.
Jim, your a smart man. You saved my ass. Learned from you and I thank you for your valuable information you've shared. Thank you!
great video. thanks for taking the time to learn about this and present it so well.
This is the best video on the subject. Thank you so much.
I enjoyed this video the guy knows what he's talking about thank you
Excellent video. Thank you for posting this! Learned something today!
Very good video. I rebuilt automatic transmissions in the 1980s and I had a flare many times for automatic transmission coolant lines. At least at that time we ONLY did double flares on the transmission lines.
Thanks for the details on the differences in lines.
Cristal clear information. The best video i´ve found. Thanks for sharing!
Should of watched this video, before I got started buying parts, thanks Jim for your " GREAT" info video !
Great video and clarifies my ignorance. Thank you for sharing.
Top quality video , thank you from Bath, England.
Thank you. Great information and just saved me some time.
Very nice video, especially for learning the process in just a few days. Happy to see you commented on using the proper flaring tool, the ISO/DIN bubble cannot be made properly using the SAE tool. Close, sure, not not correct and they often will leak. Not worth the risk.

finally an explanation. Seems many people are mixing up the nuts and flare terminations
So can i use a bubble flare as a male and mate it with a double flared end with a female nut? Some eurocars have this as standard but i can't find a video on how to make the different ends up.
Best video ever, Big Thank you, now I know what I need for my car!
Excellent video. Very informative and useful information. Best I have seen. New subscriber and will be following. Thanks for the info Artie 👍👍👍
A very informative well presented video thank you.

Best video I have seen. Great job.
Having owned older vehicles from the 1980's , this is great to update my knowledge . I have been lucky to use lines with fittings and unions . L
Great video! I've noticed OEM's have used a female flare nut with a male bubble nut rather than a union, this results in roughly half the chance for a leak! The female flare nuts are near impossible to find though.
I agree if you need a bubble flare, definitely use the correct tool!
This is the Best video out here
Best video out there! Thanks!
Superb video Jim - thank you
Great informational video.. best one yet..

Well done. VERY clearly explained. Thanks.
I work at TI automotive this is so helpful
We make brake lines and fuel pipes and fuel tanks for Mercedes’
Incredible. Excellent video.
The Very Best Video on brakes Ever
for the sake of accuracy - 3/16" is actually 4.76mm which is why we can easily substitute it for metric 4.75mm line. Other than that, great video!
4.76 is actually 3/16 and this I'm sure bugs metric fans to no end b/c they have no concept of fractions.
Very in depth and helpful thanks

Very informative video, thank you 🙏
Excellent video
such good video many thanks
Very helpful information!!!
Excelent explained . Thanks !
Awesome lesson for me thanks.
Great info! You just solved my probleo. My master cylinder fits abubble flare where as the rest of my yj fits adouble flare. Thanks!
thanks for sharing info,
Perfect, I was wondering if the bubble flair needed different fittings.
Great information
thank you!!!
I laughed at the forgotten nut. I had a similar issue last night. Welded a clevis onto Master Cylinder rod, forgot the retaining plate. Then almost forgot the rubber boot.
Thanks, very informative
Thanks for the info on this.
Thumbs up, good information.
Very good video, thank you! It explained one main thing I wanted to know, but wasn't able to find info on: can a double flare kit "simulate" a bubble flare if you're in a pinch. Apparently it can. That being said, I'll still buy the proper kits for both. :)
