How Do You Choose the Best Brake Line Flaring Tool for Your Vehicle?

Best Brake Line Flaring Tool

If you’re on the hunt for the best brake line flaring tool, this is the place to be. When buying this tool, people overlook certain factors. All they consider is the price and get the cheapest one possible. This negligence, however, is why they end up with a below-average product.

Assuming you know the basics of flaring, we have put together some factors you must consider. 


Remember, you won’t be using the kit most of the time. So, make sure to keep the dimension of the kit in mind when buying. It will enable you to store the kit when not in use without any difficulty.

But make sure it is big enough that you can easily use it.


When buying a flaring tool make sure it can withstand the test of time. Since you won’t be needing it regularly, there are chances it may wear out. Ensure that the materials used are long-lasting and can withstand years of application.


An important thing to consider when buying a brake line flaring tool is its portability. It should give you the freedom of carrying it around without worrying about its weight or size. This feature is especially necessary for professionals who must travel on the job. You cannot travel freely with a heavy toolkit in your hand or the car. Moving it around will only create unnecessary obstructions.


Considering the application is extremely important. What if you end up buying a toolset that does not meet your requirements?

For example, you get a bubble flare set when you need a double flare kit. It will be a complete waste of money and you won’t be able to use it either.


A brake line flaring tool should always be leak-proof. If not, it is of no use. This factor works in sync with the material used to make the flaring tool. Flaring tools made of thick and durable fittings ensure that there are no leaks.

Flaring tool adapters

Flaring tool kits come with many adapters. They help you piece together tricky piping sections if you use the correct size. If a flaring tool kit does not come with adapters, you’ll end up spending a lot on them individually. So, we recommend buying one with adapters, so you get the correct adapters without paying too much.

Frequently Asked Questions

Q1: Is it necessary to double flare brake lines?

Technically speaking, double flaring brake lines is not the only option. You can simply single flare them too. But it is not recommended because they crack easily and cause leakage. Double flaring is the safest option when compared to single flared brake lines.

Q3: What are the two types of flaring?

On brake lines, you can use two types of flaring–double flare and ISO bubble flare. Double flares are a more common sight than a bubble flare as they support many vehicles. 

Q4: How long does it take to repair or replace a brake line?

This depends on the person performing the job. For professionals, it may take up to two hours to fully repair and flare a brake line. As for amateurs and DIYers, it may take longer.
