When it comes to brake maintenance, one of the most critical tasks is capping brake lines. Brake lines are the hydraulic lines that connect the brake master cylinder to the brake calipers or wheel cylinders, and they play a vital role in ensuring that your vehicle comes to a stop safely and efficiently. However, over time, brake lines can become damaged, corroded, or worn out, which can lead to brake fluid leaks, reduced braking performance, and even accidents. This is where capping brake lines comes in – a process that involves replacing the old brake lines with new ones, ensuring that your brakes are functioning properly and safely.
The importance of capping brake lines cannot be overstated. Failing to do so can result in serious consequences, including brake failure, accidents, and even loss of life. In fact, according to the National Highway Traffic Safety Administration (NHTSA), brake-related problems are a leading cause of vehicle crashes, resulting in thousands of injuries and fatalities every year. Moreover, capping brake lines is a critical task that requires attention to detail, technical expertise, and the right tools and materials. If done incorrectly, it can lead to more problems than solutions.
In this comprehensive guide, we will take you through the step-by-step process of capping brake lines, including the tools and materials needed, the different types of brake lines, and the common mistakes to avoid. Whether you’re a DIY enthusiast, a professional mechanic, or a car owner looking to ensure your vehicle’s safety, this guide is designed to provide you with the knowledge and confidence to tackle this critical task.

Understanding Brake Lines
Before we dive into the process of capping brake lines, it’s essential to understand the basics of brake lines and their importance in the braking system. Brake lines are hydraulic lines that connect the brake master cylinder to the brake calipers or wheel cylinders. They are responsible for transmitting brake fluid pressure from the master cylinder to the brake pads or shoes, which then apply pressure to the brake rotor or drum to slow down or stop the vehicle.
There are two main types of brake lines: steel brake lines and rubber brake lines. Steel brake lines are the most common type and are used in most modern vehicles. They are durable, resistant to corrosion, and can withstand high pressure. Rubber brake lines, on the other hand, are more flexible and are often used in older vehicles or in applications where flexibility is required.
Brake lines can become damaged or worn out over time due to various factors, including corrosion, road debris, and wear and tear. When this happens, it’s essential to replace them with new ones to ensure that the brakes are functioning properly and safely.
Tools and Materials Needed
To cap brake lines, you’ll need the following tools and materials:
- Brake line cutter or tubing cutter
- Brake line flaring tool
- Brake line bender
- New brake lines (steel or rubber)
- Brake line fittings (e.g., banjo bolts, brake line adapters)
- Brake fluid
- Brake cleaner
- Rag
- Work light (optional)
It’s essential to use high-quality tools and materials to ensure that the job is done correctly and safely. Using cheap or inferior tools can lead to mistakes, damage to the brake system, and even accidents.

Step 1: Jack Up the Vehicle and Remove the Wheels
Before starting the job, make sure to jack up the vehicle and remove the wheels to give you clear access to the brake lines. Use a hydraulic jack and ensure that the vehicle is securely supported by jack stands.
Step 2: Locate the Brake Lines
Identify the brake lines that need to be replaced and locate their connection points to the brake master cylinder, brake calipers, or wheel cylinders. Take note of the type of brake line fittings used and the orientation of the brake lines.
Step 3: Disconnect the Brake Lines
Use a wrench or pliers to loosen the brake line fittings and disconnect the brake lines from the brake master cylinder, brake calipers, or wheel cylinders. Be careful not to spill brake fluid or damage the surrounding components.
Step 4: Remove the Old Brake Lines
Use a brake line cutter or tubing cutter to cut the old brake lines, taking care not to damage the surrounding components. Remove the old brake lines from the vehicle and discard them.
Step 5: Measure and Cut the New Brake Lines
Measure the length of the new brake lines required and cut them to size using a brake line cutter or tubing cutter. Make sure to leave enough slack for bending and fitting the brake lines.
Step 6: Flare the Brake Lines
Use a brake line flaring tool to flare the ends of the new brake lines. This will create a secure connection with the brake line fittings.
Step 7: Bend the Brake Lines
Use a brake line bender to bend the new brake lines to the required shape and orientation. Make sure to follow the original brake line routing and avoid kinking or twisting the brake lines. (See Also: What Happens if You Pull the Parking Brake While Driving? Serious Consequences)
Step 8: Connect the Brake Lines
Connect the new brake lines to the brake master cylinder, brake calipers, or wheel cylinders using the brake line fittings. Make sure to tighten the fittings securely and avoid over-tightening.
Step 9: Bleed the Brake System
Use a brake bleeding kit to remove any air from the brake system and ensure that the brake fluid is flowing properly. This will help to prevent brake failure and ensure that the brakes are functioning properly.
Common Mistakes to Avoid
When capping brake lines, it’s essential to avoid common mistakes that can lead to brake failure, accidents, and even loss of life. Some common mistakes to avoid include:
- Using inferior tools and materials
- Failing to follow proper safety procedures
- Not bleeding the brake system properly
- Not tightening brake line fittings securely
- Not using the correct type of brake line fittings
- Not following the original brake line routing
By avoiding these common mistakes, you can ensure that the job is done correctly and safely, and that your vehicle’s brakes are functioning properly.
