In this video, I use Cupro Nickel (Kunifer) brake line because it is more corrosion resistant. I use a mini brake pipe cutter because the more compact ones can fit into small places when working on the car, rather than just on the bench. I use a hand help double flare tool, again, because it can more easily be used on the car if needs be (compared to one that fits in a vice) and it is cable of doing a single flare and a double flare on a brake pipe.

Once you learn how to double flare a brake pipe, you can pretty carry out any brake pipe repair. It can be time consuming and that’s why DIY brake pipe repair is such a money saver!

🔧 TOOLS & MATERIALS 🔨

Single & Double Flare Tool

3/16” Cupro Nickel (Kunifer) Brake Line / Brake Pipe (More corrosion resistant than normal Copper)

Brake Line fittings – These should allow you to join in a new section and put a new nut / fitting onto a flexible or a brake caliper

Mini Tube Cutter – In this case, small IS better! Just in case you have to use it in situ on the car.

Brake Fluid Dot 4 for Topping Up (check that is what your car needs but most modern cars do!)

Just as a reminder. Put the correct fitting on the pipe before flaring.

Brilliant! Thank you for this video demonstration 👍

This is a great video... thank You.... I just got my flaring tool last week... haven't used it yet.... you did a great job going through step by step... much appreciated... Thank You!

Just got this type of flaring tool, with no Instructions included, so very helpful video, , you should do a bubble flare one too

Nice video. I started watching your battery load test.
I will say that I have the exact Titan double-flaring tool.
But on the car on the steel OEM line (Mazda 3 in my case) it’s not so facile.
I think you have to have a hydraulic flaring tool like the Mastercool 72485.
I double-flared my 4 wheels to accept new flexible brake line, using the Mastercool.
I found this manual tool you have (Titan-Franklin) was best to straighten out the ripple of “unbent” line. This to prepare the line for the hydraulic flaring tool.

You have to spend $ on the hydraulic tools. The hand held tool only works on the bench with soft copper-nickel spare brake line.
Cheers!

Got one of these flaring tools. They don't chew the pipe up unlike the cheap clamp type tools. Very easy to set up and operate. Produces perfect flares.

You don't need to risk damaging the end of the brake pipe with the stop if you fit the stop first while the two 10 mm bolts are still slack enough for the pipe to be gently pushed up against the stop.

Perfect set of instructions. Bought the exact kit and now feel confident to start. Thanks!

I am completely new to making flares, but i have to say this little tool that comes in so many different brands of packaging will yield the most beautiful flares...if you do it right which is not a massive learning curve. I used steel piping and that takes a LOT more force to get the job done but it does work just as well as with copper piping.

[levelman]

Cheers fella, exactly the info I needed!

[randyschmittou]

Very well made video! Thanks for sharing!

wish I watched this before eating all the grease...

I had to replace a section of 1/4" 409 stainless on my '80 Chevy 3/4 ton truck that was damaged by a "professional" mechanic. The 1/4" version of this tool was the only one that would flare the 409 stainless on my truck (inside the frame).

Hi. Excellent video!! Thinking of getting one of these. Can you tell me what the difference is between a single and double flare. And how to know which one to use? Thanks

[melvis]

Great video and thanks for sharing with us this

[nmozgeq]

Absolutely clear instructions and excellent video. Well done.

[jetmech]

You are THE Man!! Thank you very much for the demo and instructions. Exactly what I was looking for. Very helpful. I liked and subscribed. I am looking forward to more of your videos, but right now I gotta get back out to my corroded old dodge dakota and splice in new brake lines. Not a good feeling when you step on your brake pedal and it goes to the floor...
Thanks again... 2 thumbs up!!!

[jameslarson]

Thank you very much I just ordered. To be arriving today and your video help immensely

[nicam]

Am I correct in thinking that you should be using a DIN flaring tool not an SAE one? The underside of the DIN flare is flat, to match the DIN fitting...? This is soooo confusing as the market is flooded with a mixture of both, seemingly interchangeable, but they're not.... 🤔

[chrisduhaime]

That simple tool is accurate and contained/ that split wing nut tool is no good because the dies DON t have a right size steam and cannot center properly / that has been out there over 50 years ! Eye believe that it's intentional somehow the industry don't want diy to fix there own stuff.
