The Advantages of Owning a Brake Line Flaring Tool

Do you need a brake line flaring tool? Well, if you’re someone who prefers to do your own vehicle maintenance, it’s a very handy tool to have.

When problems arise, you must diagnose them and fix them before they cause dangerous problems on the road. With a brake line flaring tool in your tool kit, you’ll be well-equipped to tackle common issues like leaks in the brake line. 

Additionally, a brake line flaring tool can be quite versatile.

Types of Brake Line Flaring Tools

As you consider the many different brake line flaring tools available, you’ll want to look at type above all else. The type of tool determines what kinds of flairs it can create. You can choose a tool that offers just one type of flare, or you can opt for one that does double duty with multiple types of flares possible. It’s entirely up to you and your needs. The following are the most common types of brake line flaring tools you’ll come across. 


A single brake line flaring tool is the simplest tool — and it’s typically also the cheapest option you’ll find. These tools allow you to make quick flares, and they tend to be ideal if you need a simple single flare on your line.

However, keep in mind that single flares aren’t the most common type of flare used for brake lines. A single flare tool may not fully meet your needs, and it can come with limitations if you need to create a different kind of flare. These types of brake line flaring tools are also often made to work solely on specific materials, like brass or soft steel.


A double flare brake tool is a step up from a single tool, and it equips you to create double flares in brake lines. They can work with common brake line sizes and materials, and they create a more durable kind of flare that isn’t so prone to cracks. Though you’ll only be able to make double flares, that may be exactly what you need.

Because double flares are the most common type of flare used in brake lines, a double flare tool can be a particularly beneficial type to choose. You’ll likely get a lot of use out of this very common option. 


A bubble flare tool is one of the most specialized options you can choose — and that also makes it one of the most costly. This type of brake line flaring tool creates a screw-style opening at the end or opening of your line, and it allows for attaching accessories or compatible attachments.

You’ll want to consider whether you need to make bubble flares in your brake line. If you don’t see yourself doing that, this kind of tool might be too specialized and a bit too fancy for your needs. It could save you money if you opt for something simpler.

Complete or Combination

Lastly, you can choose a brake line flaring tool that can create multiple types of flares. These tools are typically called complete or combination flare tools. They can create two types of flares, like single and double or double and bubble. Or they might be able to create every type of flare. 

Complete or combination flare tools can give you the ultimate level of versatility. You’ll be equipped for anything, and that can be very valuable when you’re trying to decide what your brake line needs. Attachments, adapters, and accessories can add even more versatility, with features like measurements in SAE and metric, sizing for various brake lines, and more.

What to Consider When Buying a Brake Line Flaring Tool

Once you’ve settled on the type of brake line flaring tool that’s best for your needs, you’ll want to consider different features to make sure you’re choosing a product that’s worth your investment. A quality brake line flaring tool will offer the types of flares you need to perform. But you’ll also want to consider the material — or what the tool itself is made out of. Brake line flaring tools can be made out of everything from plastic to metal. For long-term durability, it’s best to opt for a tool that’s made out of metal. Steel, particularly heat-treated steel, for example, offers great strength.

You’ll want to also consider the convenience and portability of the tool or toolset. Does it come with adaptors to suit different brake line sizes? Does it include any other items that offer more versatility or extra convenience, like a line cutter? If the tools are packaged for extra portability, that can offer additional perks. You can keep the tool and its parts organized, and you can bring it with you wherever it’s needed. 

Best Brake Line Flaring Tools FAQ:

As you consider and compare different brake line flaring tools, you’ll likely come across some questions. These might seem like pretty simple tools, but choosing which one, in particular, is best for you and your car’s brake system can be tricky. Fortunately, we’re here to answer some of the most commonly asked questions about choosing and using a brake line flaring tool.

Q: Do brake lines need to be double flared?

Double flares are the most common way brake lines are flared. Single flares are an option, but they tend to be a less durable and lasting choice than a double flare.

Q: Can you use compression fitting on a brake line?

You can opt to use a compression fitting, but it isn’t recommended. A compression fitting won’t be a reliable choice, meaning you’ll likely find yourself needing to stop another leak soon.

Q: How long does it take to replace a brake line?

This can vary quite a bit. The replacement process will depend on your vehicle and the complexity of your vehicle’s braking system. It could take an hour or two, or it could take longer if it’s your first time performing these repairs.
