Things to Consider Before Buying Brake Line Flaring Tool
Before you set about choosing the right brake line flaring tool for your car, there are some factors you need to keep in mind. Here they are.
It’s no secret that brake line flaring tool kits are somewhat expensive. So it’s your job to ensure that the materials used in making the tools are durable.
The best material, in our opinion, is a copper-nickel alloy, as they are sturdy and ensure longevity.
Portability & Storage
Automotive tools should all be made such that they can be easily stored in your car and moved when required. Especially if you’re a professional, this can obviously be a huge help.
Car’s Brake System
Before you buy a brake line flaring kit, you have to first ensure that the tools in the kit will match with the measurements of your brake lines and pipes.
This has less to do with the flaring tool you will buy and more with the overall process. You need to be well-acquainted with the fittings of your car’s brake system so you can purchase the right tool.
The three parts of a flaring tool are a crew, a metal piece, and a metal bar. Together, these components ensure your tool kit’s efficiency. Your brake line flaring tool should be able to make tight fittings with ease.
Flaring tools can be pretty expensive. However, single flaring tools do tend to be cheaper, so if you’re not going to be making heavy-duty applications, you should be fine.
At the same time, single-flaring isn’t exactly recommended. Furthermore, when it comes to automotive tools, you usually get what you pay for. Don’t buy poor-quality tools for your car!
FAQs for Brake Line Flaring Tool
1. Why do I need to flare my car’s brake lines?
You don’t absolutely need to, but it does make a difference. The end of the brake line’s tubing is made wider if you flare it. This allows for an easier connection, thereby lowering the possibility of a leak.
2. Do I have to double-flare my brake lines?
It’s not necessary, but it’s certainly recommended. This is because single-flaring makes it more likely that the brake lines will crack.
3. Is it possible to drive a car with a leaking brake line?
Yes, it’s possible, but that doesn’t mean you should do it. Not only is it very dangerous, but it can permanently damage your brakes. So only do it if or when you have no other choice.
4. What is the best material to make brake lines out of?
Copper-nickel alloy is the most popular option thanks to its durability and sturdiness. A similarly durable material is stainless steel.
5. What size should my brake line be?
The most common size for brake lines is 3/16”/4.75mm and 1/4”.
