When it comes to vehicle maintenance and repair, one of the most critical components to focus on is the brake system. Brake lines play a vital role in ensuring the safety and reliability of your vehicle’s braking performance. A faulty or damaged brake line can lead to brake failure, which can have disastrous consequences on the road. Therefore, it is essential to know how to make brake lines to ensure your vehicle is running safely and efficiently.
Overview of Brake Lines
Brake lines are an integral part of the brake system, responsible for carrying brake fluid from the master cylinder to the brake calipers or wheel cylinders. They are typically made of steel, stainless steel, or nylon tubing, and are designed to withstand the high pressure and heat generated by the braking system. Over time, brake lines can become damaged or corroded, leading to leaks, brake fluid loss, and ultimately, brake failure.
Why Make Your Own Brake Lines?
Making your own brake lines can be a cost-effective and efficient way to repair or upgrade your vehicle’s brake system. By doing so, you can ensure that your brake lines are custom-made to fit your specific vehicle’s needs, and are made with high-quality materials that meet or exceed OEM standards. Additionally, making your own brake lines can be a valuable learning experience, allowing you to develop your DIY skills and gain a deeper understanding of your vehicle’s brake system.
In this guide, we will take you through the step-by-step process of making brake lines, including the materials and tools needed, the fabrication process, and the installation and testing procedures. Whether you’re a seasoned mechanic or a DIY enthusiast, this guide will provide you with the knowledge and confidence to make your own brake lines and ensure your vehicle is safe and reliable on the road.
How to Make Brake Lines: A Comprehensive Guide
Brake lines are an essential component of a vehicle’s braking system, and making them requires attention to detail, precision, and the right tools. In this article, we will take you through a step-by-step guide on how to make brake lines, covering the necessary materials, tools, and techniques involved.
Materials Needed
To make brake lines, you will need the following materials:
- Brake line tubing (stainless steel or copper-nickel alloy)
- Fittings (brake line adapters, brake line unions, and brake line tees)
- Brake line flares (single or double)
- Brake line washers
- Brake line lubricant
- Teflon tape
- Tube cutter
- Tubing bender
- Flare tool
- Wrenches and sockets
Tools Needed
In addition to the materials, you will need the following tools:
- Tubing cutter: used to cut the brake line tubing to the desired length
- Tubing bender: used to bend the brake line tubing into the desired shape
- Flare tool: used to create the flares on the brake line tubing
- Wrenches and sockets: used to tighten and loosen the fittings
- Teflon tape applicator: used to apply Teflon tape to the threads of the fittings
- Brake line lubricant applicator: used to apply brake line lubricant to the brake line washers
Step 1: Measure and Cut the Brake Line Tubing
The first step in making brake lines is to measure and cut the brake line tubing to the desired length. Make sure to measure carefully, as incorrect measurements can lead to brake line failure.
To measure the brake line tubing, follow these steps: (See Also: Why Does My Car Jolt When I Brake)
- Measure the distance between the brake master cylinder and the brake caliper or wheel cylinder.
- Add 10-15% to the measured distance to account for any bends or turns in the brake line.
- Use a tubing cutter to cut the brake line tubing to the desired length.
Step 2: Bend the Brake Line Tubing
Once the brake line tubing is cut to the desired length, it needs to be bent into the desired shape. Use a tubing bender to bend the brake line tubing, as it will help prevent kinking or damage to the tubing.
To bend the brake line tubing, follow these steps:
- Use a tubing bender to bend the brake line tubing into the desired shape.
- Make sure to bend the tubing slowly and carefully to prevent kinking or damage.
- Use a tubing bender with a mandrel to help maintain the shape of the tubing.
Step 3: Create the Flares
After bending the brake line tubing, the next step is to create the flares. Flares are essential in brake lines, as they provide a secure connection between the brake line tubing and the fittings.
To create the flares, follow these steps:
- Use a flare tool to create the flares on the brake line tubing.
- Make sure to create the flares slowly and carefully to prevent damage to the tubing.
- Use a flare tool with a mandrel to help maintain the shape of the flare.
Step 4: Assemble the Brake Lines
Once the flares are created, the next step is to assemble the brake lines. Make sure to assemble the brake lines carefully, as incorrect assembly can lead to brake line failure.
To assemble the brake lines, follow these steps:
- Apply Teflon tape to the threads of the fittings.
- Apply brake line lubricant to the brake line washers.
- Attach the fittings to the brake line tubing, making sure they are securely tightened.
- Use wrenches and sockets to tighten and loosen the fittings.
Step 5: Test the Brake Lines
Once the brake lines are assembled, the final step is to test them. Testing the brake lines is crucial to ensure they are functioning properly and safely.
To test the brake lines, follow these steps: (See Also: What Is A Brake Backing Plate)
- Connect the brake lines to the brake master cylinder and brake caliper or wheel cylinder.
- Apply pressure to the brake pedal to test the brake lines.
- Check for any leaks or damage to the brake lines.
- Make any necessary adjustments to the brake lines.
Conclusion
Making brake lines requires attention to detail, precision, and the right tools. By following the steps outlined in this guide, you can create brake lines that are safe and functional. Remember to always follow proper safety protocols when working with brake lines, and consult a professional if you are unsure about any part of the process.

Frequently Asked Questions: How to Make Brake Lines
What materials do I need to make brake lines?
To make brake lines, you’ll need a few essential materials, including brake line tubing (available in various sizes and materials, such as stainless steel or nylon), brake line fittings (e.g., flare nuts, compression fittings), a tubing cutter, a flare tool, and a brake line bender. You may also need some lubricant, such as silicone-based grease, to protect the fittings and tubing from corrosion.
How do I determine the correct brake line size for my vehicle?
To determine the correct brake line size for your vehicle, you’ll need to consult your vehicle’s repair manual or the manufacturer’s specifications. The brake line size is typically measured in inches or millimeters and is dependent on the vehicle’s brake system configuration and the type of brake fluid used. You can also measure the existing brake lines to ensure you get the correct replacement size.
What is the difference between a double flare and a single flare brake line?
A double flare brake line has two flares, one at each end, which provides a more secure connection and helps prevent brake fluid leaks. A single flare brake line, on the other hand, has only one flare at one end and is typically used for brake line repairs or modifications. Double flare brake lines are generally recommended for most brake system applications due to their added safety and reliability.
Can I use a brake line kit or do I need to fabricate my own brake lines?
A brake line kit can be a convenient and cost-effective option, especially if you’re not comfortable fabricating your own brake lines. These kits usually include pre-cut and pre-flared brake lines, fittings, and instructions specific to your vehicle make and model. However, if you have a custom or modified brake system, you may need to fabricate your own brake lines to ensure a proper fit and safe operation.
How do I properly bend brake lines to avoid kinking or damage?
To properly bend brake lines, use a brake line bender, which helps maintain the tubing’s integrity and prevents kinking or damage. Start by marking the tubing where you want to make the bend, then use the bender to create a smooth, gradual curve. Avoid using pliers or other tools that can crush or deform the tubing, as this can lead to brake system failure or leaks.
