How to create a double flare tool for brake lines?

In this section, we will discuss how does a double flare tool work.Using a double flare tool required a bit of concentration because any mistake can cause an unsuspected result.Process of making a double flare can be a little tricky and serious concern if you don’t have the right tool. So, make sure to get the best one.

Nevertheless, let’s assume you have got one. Besides tools, you would also need to have a cutter, yoke, and brake line.

In general,the brake line comes in 25 feet of a roll. And the others you can get inside a double flare toolset. So, at first, you would need to unravel a piece of the brake line. Now, for this purpose, we are going to cut two inches off. To do that, you insert the tube between the two rollers against the cutting wheel, and you tighten the tube cutter. You have to cut it until the tube is into the little piece.

After placing the double flaring bar into the vise, you now want to insert your tube into the proper hole and snap on double flare tool. You will notice, there are numbers along the top, those ranges from a quarter to 3/16. So, we are going to place the 3/16 brake lines into the corresponding hole and tighten the wing nuts down securely.

Next, take the tube cutter and use it to remove the inside chamfer on the brake line.We have to do this by pressing and rotating.

Because of using the 3/16 brake line, we have to pick an adapter that sized 3/16 inches.You will notice on the side of the adapter that there is a little step. The step corresponds with the top of the tube. To lower the tube down,we should loosen the wing nuts and lower the tube to the top of the adapter. Afterward, tighten the wing nuts.

The next step we have to do is producing a single flare. So, we will take the adapter and turn it into two, and then we will take the yoke and will place it over top of the flaring bar. Then we will turn the cone down. Make sure to tighten that enough until the adapter hits the bar. Now, we are done with a single flare, which is our first step.

In the next phase, we are going to produce a double flare. We are going to do that by placing the cone into the tube and turn it again. Then loosen the wing nuts. If everything goes right, what we will see is the double flare. So, that is all about how to use a double flare tool for the brake line.
