Benefits of Brake Line Flaring Tool
- Perform your own repairs. Owning a brake line tool will save you money and time. You will not need to call a professional to replace rotted or broken brake lines, nor will you need to invest in costly premade lines.
- Can be used for other projects. A flaring tool can be used for flaring other tubing on the vehicle or elsewhere. If you intend to do so, you will need to select a kit that can be used with the proper materials and tubing diameters.
- Easy to use. Flaring tools are very simple to use and only require a little practice. Even the most intricate designs only require a basic understanding of mechanical systems and a review of the instructions.
Types of Brake Line Flaring Tools
These flare tools use a bar and yoke to flare lines. The bar clamps the brake line in place, and the yoke is used to drive the flare adapter into the line to create a flare. Most of those on the market do not require additional tools for the operation, but there are exceptions.
These flare tools use hydraulic power to drive the flare adapter into the line instead of a fastening design. These are ideal for professionals because they provide unmatched performance and can even be operated in a single hand. However, they are far more expensive than traditional offerings.
Traditional and hydraulic designs are often too large to use for flaring lines on a vehicle. These tools feature a single opening for lines and an interchangeable adapter. They may only be compatible with a single diameter of tubing, but it will make quick work of flaring tools that are already on the vehicle.

Brake Line Flaring Tool Pricing
- Under $20: Kits that list for less than $20 are basic and intended only to flare lines. Many subpar options are present, but some offer great performance.
- $20-$50: A variety of flaring tools exist in this price range. However, it is mostly dominated by traditional kits of decent quality.
- $50-$100: Compact and professional-grade tools begin to appear in this price range. While many are similar to cheaper options, better materials and construction are typical.

Use of cheap or flimsy materials and poor designs are the first things to watch out for. You must use a tool that is capable of producing a quality flare each time you use it because your life can depend on it. Poorly designed tools and bad castings can cause deviations that prevent the line from sealing properly or failing prematurely.
A simple operation is always ideal. You never want to invest in a tool that’s clumsy or hard to use. A complicated process can result in poor quality results. Most flare tools follow a simple design, but others depend on additional tools and procedures you may not be familiar with.

Useful Flaring Styles
Not all flare tools produce the same flares. For example, some only make a single flare type that you may not be able to use. Always be sure to select a tool that can produce the flares your application requires. Otherwise, you might not create a good seal, or the flare simply may not be useable.
- Storage Case. A storage case is always something to look for. Some kits come with a simple plastic tray to hold the components of a flare tool. While it works great initially, it will eventually fail. Therefore, when purchasing one of these tools, it’s wise to consider those that at least come with a blow-molded case.
- Inclusion of Necessary Tools. A flaring tool can only flare the lines. It will not file or deburr lines, nor will it cut them. You will need additional tools to perform these tasks. That’s why it’s always a good idea to invest your money in an inclusive kit. If they don’t, you will need to make additional investments.
- Compatibility with Larger Tubing. Most brake lines are small in diameter, but a flare tool is necessary for larger lines found in other plumbing systems. If you work on fuel lines, plumbing systems, or HVAC components, you may want to invest in a kit that can be used to flare wider tubing.

- As you flare a line, you need to be careful not to apply too much pressure. Otherwise, the flare is likely to crack and fail prematurely.
- Before flaring a line, you must be sure to ensure the end is cut as straight as possible and free of any burs. If you don't, it will fail to seal correctly.
- Take your time to make sure you are producing the best flare possible, even if it means taking a few shots at it. Rushing to a finish will likely lead to failure of the line if details are overlooked.
