How to Run Brake Lines: A Comprehensive Guide
Running brake lines is a crucial step in the brake system installation process. It requires careful planning, precise measurement, and attention to detail to ensure proper function and safety. In this article, we will provide a step-by-step guide on how to run brake lines, covering the necessary tools, techniques, and best practices.
Preparation and Planning
Before starting the brake line installation process, it is essential to prepare and plan carefully. This includes:
- Reviewing the vehicle’s brake system diagram to understand the layout and routing of the brake lines
- Measuring the distance between the brake master cylinder and the brake calipers or wheel cylinders
- Choosing the correct type and size of brake line fittings and tubing
- Ensuring the necessary tools and equipment are available, including tubing cutters, flares, and tubing benders
It is also important to ensure the brake system is free from any debris or contaminants that may interfere with the installation process. (See Also: How Many Brake Pads Per Box)
Routing the Brake Lines
The brake line routing process involves tracing the path of the brake lines from the brake master cylinder to the brake calipers or wheel cylinders. The goal is to create a smooth, straight, and secure route that minimizes bends and kinks.
Here are some general guidelines for routing brake lines:
- Route the brake lines along the frame rails or suspension components to reduce exposure to heat and vibrations
- Avoid routing brake lines near hot surfaces, such as exhaust systems or engine components
- Keep brake lines away from sharp edges or corners that may cause damage or kinking
- Use tubing clips or brackets to secure the brake lines to the vehicle’s frame or suspension components
It is also important to consider the following factors when routing brake lines:
- Clearance: Ensure the brake lines have sufficient clearance to avoid interference with other components or systems
- Flexibility: Route the brake lines to allow for flexibility and movement, such as when the vehicle suspension is compressed or extended
- Protection: Route the brake lines to protect them from damage or corrosion, such as by using protective tubing or shielding
Flaring and Fitting Brake Lines
Once the brake lines are routed, it is necessary to flare and fit them to the brake calipers or wheel cylinders. This involves:
- Using a tubing flaring tool to create a flare on the end of the brake line
- Attaching the flare to the brake caliper or wheel cylinder using a fitting or adapter
- Securing the fitting or adapter to the brake caliper or wheel cylinder using a nut or bolt
Here are some tips for flaring and fitting brake lines:
- Use the correct size and type of flare tool for the brake line and fitting
- Apply even pressure to the flare tool to avoid damaging the brake line or fitting
- Check the flare and fitting for proper alignment and securement

Testing and Bleeding the Brake System
After installing the brake lines, it is essential to test and bleed the brake system to ensure proper function and to remove any air that may have entered the system during the installation process. (See Also: How Long To Do A Brake Job)
Here are the steps to test and bleed the brake system:
- Fill the brake master cylinder with the recommended type and amount of brake fluid
- Check the brake fluid level and top it off as necessary
- Test the brake system by pressing the brake pedal and checking for proper brake function
- If the brake system is not functioning properly, bleed the system by opening the bleed screws and allowing air to escape
- Repeat the bleeding process until the brake system is functioning properly and there is no air in the system
It is also important to check the brake fluid level regularly and top it off as necessary to ensure proper brake function and to prevent corrosion and damage to the brake system components.
Recap and Key Points
Running brake lines requires careful planning, precise measurement, and attention to detail to ensure proper function and safety. Here are the key points to remember:
- Review the vehicle’s brake system diagram and measure the distance between the brake master cylinder and the brake calipers or wheel cylinders
- Choose the correct type and size of brake line fittings and tubing
- Route the brake lines along the frame rails or suspension components to reduce exposure to heat and vibrations
- Use tubing clips or brackets to secure the brake lines to the vehicle’s frame or suspension components
- Flare and fit the brake lines to the brake calipers or wheel cylinders using the correct size and type of flare tool and fitting
- Test and bleed the brake system to ensure proper function and to remove any air that may have entered the system during the installation process
By following these steps and guidelines, you can ensure a successful brake line installation and proper brake function for your vehicle.
Remember to always follow proper safety procedures and guidelines when working with brake systems, and consult a professional mechanic if you are unsure or uncomfortable with any aspect of the process.
Here are five FAQs related to “How To Run Brake Lines” with headings, questions, and answers:
Frequently Asked Questions
What tools do I need to run brake lines?
To run brake lines, you’ll need a few basic tools, including a brake line kit, tubing benders, tubing cutters, and a flare nut wrench. You may also need a tubing deburrer and a brake line cleaner, depending on the type of brake line you’re using. (See Also: How Long Brake Pads Last On A Car)
How do I measure for brake lines?
To measure for brake lines, start by measuring the distance from the master cylinder to the brake caliper. You’ll also need to measure the distance from the brake caliper to the wheel hub. Add a few inches to each measurement to allow for any bends or kinks in the line. Use a brake line kit that’s specifically designed for your vehicle’s make and model to ensure the correct length and routing.
How do I bend brake lines?
To bend brake lines, use a tubing bender and follow the manufacturer’s instructions. Start by bending the line in small increments, checking the bend as you go to make sure it’s even and smooth. Use a tubing deburrer to remove any sharp edges or burrs that may be left behind.
How do I connect brake lines to the master cylinder and brake calipers?
To connect brake lines to the master cylinder and brake calipers, use a flare nut wrench to tighten the flare nuts onto the master cylinder and brake calipers. Make sure the lines are securely attached and not leaking. Use a brake line cleaner to clean up any excess brake fluid that may have spilled during the installation process.
What are some common mistakes to avoid when running brake lines?
Some common mistakes to avoid when running brake lines include kinking or bending the line too tightly, which can restrict brake fluid flow and cause the brakes to fail. Another mistake is not using a brake line kit specifically designed for your vehicle’s make and model, which can lead to incorrect routing and poor performance. Finally, not tightening the flare nuts securely enough can cause the lines to leak and lead to brake failure.
