Double Flare Brake Line Tool: What It Is and How to Use It

If you’ve ever had to work on your car’s brakes, you know that it’s important to have the right tools. One of the most essential tools for brake work is a double flare brake line tool.

A double flare brake line tool is used to create a double flare on the end of a brake line. This is necessary to create a secure seal between the brake line and the fitting on the brake caliper.

In this article, I’ll explain what a double flare is, why it’s important, and how to use a double flare brake line tool. I’ll also provide some tips for choosing the right tool for the job.

What is a Double Flare?

A double flare is a type of crimp that is used to create a secure seal between two pieces of metal. In the case of brake lines, a double flare is used to seal the end of the brake line to the fitting on the brake caliper.

Double flares are made by using a special tool to create two crimps in the end of the brake line. The first crimp is called the primary flare, and the second crimp is called the secondary flare.

The primary flare is the larger of the two crimps, and it is located closer to the end of the brake line. The secondary flare is smaller than the primary flare, and it is located further away from the end of the brake line.

Double flares are important because they provide a secure seal that prevents leaks. This is essential for ensuring the safety of your brakes.

How to Use a Double Flare Brake Line Tool

Using a double flare brake line tool is relatively simple. However, there are a few things you need to keep in mind in order to get the job done correctly.

First, you need to make sure that you have the right tool for the job. There are a number of different double flare brake line tools available on the market, so it’s important to choose one that is compatible with the size of your brake lines.

Once you have the right tool, you can begin by preparing the end of the brake line. This involves removing any burrs or sharp edges from the end of the line.

Next, you need to insert the end of the brake line into the tool. The tool will have two dies, one for the primary flare and one for the secondary flare.

Once the end of the brake line is inserted into the tool, you can begin to crimp it. To do this, you simply turn the handle of the tool until the two dies crimp the end of the brake line.

It’s important to crimp the brake line evenly. If you crimp it too tightly, you could damage the line. If you crimp it too loosely, the seal may not be secure.

Once you have crimped the brake line, you can remove it from the tool. The brake line is now ready to be installed on your car.

Tips for Choosing the Right Double Flare Brake Line Tool

When choosing a double flare brake line tool, there are a few things you need to keep in mind.

First, you need to consider the size of your brake lines. The tool you choose needs to be compatible with the size of your lines.

Second, you need to decide what type of tool you want. There are two main types of double flare brake line tools: manual and pneumatic. Manual tools are operated by hand, while pneumatic tools are operated by air.

Manual tools are typically less expensive than pneumatic tools, but they are also more difficult to use. Pneumatic tools are more expensive, but they are also easier to use.

Finally, you need to decide how much you are willing to spend on a double flare brake line tool. Prices range from around $20 to $100, so you need to decide what your budget is.

A double flare brake line tool is an essential tool for anyone who works on their car’s brakes. By following the tips in this article, you can choose the right tool for the job and use it correctly to ensure the safety of your brakes.
