Brake Line Flaring Tool Types
There are various styles of brake line flaring tools available on the market – Conventional, Vise Mounted, Hydraulic, and On Car Flaring Tools. Let’s find out which one is the perfect style for you.
Conventional Flaring Tool
This style of flaring tools is the most affordable brake line flaring tool you can purchase. But, they are inefficient and take a longer time for making flares. Some of these tools can only create single and bubble flares. If you want to stick with the conventional style, make sure it is capable of producing double flares.
Vise Mounted Flaring Tool
It is the professional and convenient style of the flaring tools. The method is effortless – first, mount the tool on the vise and insert the brake line into the right die adapter size, rotate the turret-style indexed head accordingly, then press the T-handle and you’re done!
You can create a large number of flares within a short time by using the vise mounted brake line flaring tool. Also, the quality of the flares produced by these tools is excellent. You can make all kinds of flares (Single, Bubble, and Double) by these tools. We suggest you to get one of these tools, and you’ll love it.
Hydraulic Flaring Tool
Hydraulic tools are versatile, durable, and efficient. But they are expensive, and the method is slower than a vise mounted flaring tool. You can use it to create all kinds of standard and metric flares on brake lines, fuel lines, GM-connect lines, cooling lines, etc.
You’ll get a set of die adapters with the hydraulic flaring tool kit for different line sizes. If you prefer hydraulic tools, you can get one of them.
On Car Flaring Tool
This is a handheld tool that can be used to make flares by retaining the brake line on the car. These are compact tools that can be used under the hood where other styles of flaring tools do not fit. Owning an on car flaring tool is always an advantage for you.
No matter what types of flares you’re creating, the quality of the flares is very crucial. If your brake line flaring tool cannot create high-quality flares, there will be a possibility of a brake fuel leak, which can cause brake failure.
You should not buy a cheap flaring tool. Go for the vise mounted or hydraulic brake flaring tool for excellent flare quality.
You may require to create flares on brake lines of distinct sizes. The conventional lines are – 3/16″, 1/4″, 5/16″, 3/8″, 1/2″, 4.75mm, 6mm, 8mm, and 10mm. So make sure the flaring tool you’re buying; it accepts most of these standard and metric brake lines.
Brake Line Flaring Tools Frequently Asked Questions (FAQs)
What is a brake flare tool?
A brake line flaring tool is a special tool used for making perfect flares on brake lines. You can make single, double or bubble flares on brake lines with these tools.
What is the most common brake line size?
The most common brake line sizes are 3/16 inch (4.75 mm) and 1/4 inch. While the 3/16 inch lines are vastly used on the modern vehicles both on disc and drum brakes, you will also find drum brakes with ¼ inch brake lines. In general, 3/16 inch lines are easy to bend and work with.
Do you have to flare brake lines?
Yes, you have to flare the brake lines. Brake line flares make the connection seamless and leak-free. If brake fluid leaks, there will be a lack of brake fluid pressure, and the brake caliper will not work perfectly.
How do you flare a brake line?
To flare brake lines, you’ll need a brake line flaring tool. These tools come in three different styles, and you can use any of them to flare the brake lines.
First, you need to cut the tube in the required length and remove the burrs. Then put the flare fitting on (important), and follow the user’s guide to make double or bubble flares.
Are brake lines single or double flare?
Automotive brake lines are required to be double flared. You can also make bubble flare brake lines. But never do single flared lines – they aren’t reliable and will cause brake fluid leakage, which is dangerous.
Can I use a single flare on brake lines?
Single flares on automotive brake lines are not allowed – they crack and leak very often. Ensure the brake lines are double, or bubble flared because they provide better protection against brake fluid leaks and have better longevity.
What is an inverted flare?
An inverted flare is another term of SAE double flare. Call it what you want to, SAE/Double/Inverted flares are the same thing.
Is inverted flare the same as double flare?
Yes, inverted flare is the same thing as a double flare. It is also called the SAE flare.
Can you flare stainless steel tubing?
Flaring stainless steel tubings require more strength than flaring nickel-copper tubings. The conventional brake flare tool might not work for stainless steel tubing. You will need to use a vise-mounted professional flaring tool for that task.
What angle flare is used on brake lines?
In brake lines, you’ll see two different angle flares – 37 and 45 degrees. In most of the automotive brake lines, the 45-degree angle flare is used. The 37-degree flare is especially used in A.N. (Army/Navy) applications.
Can I replace my own brake lines?
With the right tool, you can easily replace brake lines yourself. Get a brake flaring tool, and a tubing cutter, then do some practices.
Can you drive a car with a leaking brake line?
You shouldn’t drive a car with a leaking brake line (brake fluid), because your braking system will not work perfectly. It can cause brake failure, which is dangerous.
