Lastly, a deburring tool is essential for removing any burrs or rough edges from the cut ends of the tubing. Burrs can cause leaks and weaken the integrity of the brake lines, so it is important to deburr the cut ends before installing the lines. A deburring tool will ensure that the ends of the tubing are smooth and free from any imperfections, allowing for a secure connection to fittings. Using a deburring tool is a simple yet crucial step in the brake line installation process that should not be overlooked.
Preparing the Brake Line
Measure and Mark
Before you begin working on your brake line, it is crucial to accurately measure and mark where you will need to cut. Using a measuring tape or ruler, determine the length of brake line you will need for your specific vehicle. Make sure to account for any bends or curves in the line as well. Once you have the measurements, use a pencil or marker to clearly mark the cutting points on the tubing.
Cut the Line
With the brake line properly measured and marked, it’s time to make the cut. Using a tubing cutter or hacksaw, carefully cut the tubing at the marked points. Make sure to apply even pressure and keep the cut as straight as possible to ensure a clean and precise cut. Avoid using excessive force, as this could result in jagged edges or an uneven cut.
Deburr the Cut End
After cutting the brake line, it is essential to deburr the cut end to prevent any sharp edges that could potentially damage the fittings or cause leaks. A deburring tool is the best option for this task, as it can quickly and effectively remove any burrs or rough edges left from the cutting process. Simply insert the deburring tool into the cut end of the tubing and rotate it to smooth out the edges.
By following these steps to prepare your brake line, you will ensure a proper fit and secure connection when it comes time to install it in your vehicle. Taking the time to measure accurately, cut cleanly, and deburr the ends will result in a professional-looking finish that is both safe and reliable. Remember, attention to detail in the preparation stage will make the rest of the brake line installation process much smoother and more successful.
Bending Techniques
Using a Bender Tool
When it comes to bending brake lines, using a bender tool can make the process much easier and more precise. Bender tools are specifically designed to bend tubing without causing kinks or deformities. They come in various sizes to accommodate different diameters of tubing.

- Measure and mark the tubing before bending
- Place the tubing into the bender tool
- Slowly apply pressure to bend the tubing
- Check the angle to ensure it matches your requirements
Using a Vice and Hammer
If you don’t have access to a bender tool, you can also bend brake lines using a vice and hammer. While this method may not be as precise as using a bender tool, it can still be effective with some practice. Simply place the tubing in the vice and carefully hammer it to the desired angle. Be sure to take your time and make small adjustments as needed to avoid over-bending or kinking the tubing.
- Secure the tubing in a vice
- Carefully hammer the tubing to bend it
- Make small adjustments as needed
- Check the angle for accuracy
Using a Tube Bender
Another option for bending brake lines is to use a tube bender. Tube benders are similar to bender tools but are specifically designed for bending tubing. They come with various dies to accommodate different tubing sizes and can create precise bends with ease. To use a tube bender, simply insert the tubing into the die and slowly crank the handle to bend the tubing to the desired angle. This method is great for achieving professional-looking bends without the risk of damaging the tubing.
- Choose the appropriate die for your tubing size
- Insert the tubing into the die

Flaring the Ends
Clamp in Flaring Tool
When it comes to flaring the ends of your brake line, one of the first steps is to securely clamp the line in the flaring tool. This ensures that the line remains stable and in place while you apply pressure to create the flare. The clamp should be tight enough to hold the line firmly, but not so tight that it damages the line itself.
Apply Pressure to Flare
Once the line is securely clamped in the flaring tool, it’s time to apply pressure to create the flare. This step requires a steady hand and a good amount of force to ensure that the flare is formed correctly. Be sure to follow the instructions provided with your flaring tool to ensure that you are applying the right amount of pressure for the size of your brake line.
Check for Proper Flare
After you have applied pressure to flare the end of the brake line, it’s important to check for a proper flare. A proper flare will have a smooth, uniform shape and will fit securely into the fitting it is meant to connect to. Take the time to inspect the flare closely to ensure that it meets the necessary specifications for your brake system.
- Is the line securely clamped in the flaring tool?
- Are you applying enough pressure to create a proper flare?
- Have you checked the flare for any imperfections or inconsistencies?
Remember, the flaring process is crucial to the overall functionality of your brake system, so it’s important to take your time and ensure that each flare is done correctly. By following these steps and paying attention to detail, you can successfully flare the ends of your brake line and ensure a secure connection for your vehicle’s braking system.
Installing the Brake Line
