Changing brake lines is a crucial maintenance task for any vehicle, as it ensures the safe and efficient operation of the braking system. Brake lines are responsible for transmitting brake fluid pressure from the master cylinder to the brake calipers, and over time, they can become damaged, corroded, or worn out, leading to reduced braking performance and potentially even accidents. In this article, we will provide a comprehensive guide on how to change brake lines, covering the necessary tools, steps, and precautions to ensure a successful and stress-free process.
Why Change Brake Lines?
There are several reasons why brake lines may need to be changed. Some common causes include:
– Corrosion: Brake lines are prone to corrosion, especially in areas with high humidity or salt usage on roads. Corrosion can weaken the lines and lead to leaks or failure.
– Wear and tear: Brake lines are subject to constant pressure and flexing, which can cause them to wear out over time. As the lines wear out, they may become brittle and prone to cracking.
– Damage: Brake lines can be damaged during accidents, road debris, or other incidents. Even minor damage can compromise the integrity of the lines and affect braking performance.
Tools and Materials Needed
To change brake lines, you will need the following tools and materials:
– New brake lines (correctly sized and type for your vehicle)
– Brake line wrench or pliers
– Socket wrench or ratchet and socket set
– Torque wrench
– Brake fluid (if you need to flush the system) (See Also: How Long To Do A Brake Job)

How to Change Brake Lines: A Step-by-Step Guide
Changing brake lines is a crucial maintenance task that requires attention to detail and some mechanical skills. In this article, we will provide a comprehensive guide on how to change brake lines, covering the necessary tools, steps, and precautions to ensure a successful replacement.
Why Change Brake Lines?
Brake lines are an essential component of a vehicle’s braking system, responsible for transmitting brake fluid pressure from the master cylinder to the brake calipers. Over time, brake lines can deteriorate due to corrosion, wear, and tear, which can lead to reduced braking performance, leaks, and even complete failure. Changing brake lines is a necessary step to ensure the safety and reliability of your vehicle’s braking system.
Tools and Materials Needed
To change brake lines, you will need the following tools and materials:
- Braided brake line kit (new lines and fittings)
- Brake line flaring tool
- Brake line tubing cutter
- Tube bender
- Wire brush
- Rust remover (optional)
- Brake fluid (new or recycled)
- Wheel chocks (optional)
- Jack and jack stands (optional)
Step-by-Step Instructions
Changing brake lines involves several steps, which are outlined below:
Step 1: Jack Up the Vehicle and Remove the Wheels
Before starting the replacement process, make sure the vehicle is securely supported by jack stands and the wheels are removed. This will give you clear access to the brake lines.
Important: Always refer to your vehicle’s owner’s manual for specific instructions on how to jack up and support your vehicle. (See Also: How To Relieve Brake Pressure)
Step 2: Identify the Faulty Brake Line
Inspect the brake lines for signs of damage, corrosion, or wear. Identify the faulty line and mark it with a marker or a piece of tape to avoid confusion during the replacement process.
Step 3: Disconnect the Brake Line Fittings
Use a wrench or pliers to loosen the brake line fittings at the master cylinder, brake calipers, and other components. Once loose, use a wrench to remove the fittings from the brake lines.
Step 4: Remove the Old Brake Line
Use a tube cutter to cut the old brake line at the marked point. Remove the old line from the vehicle, taking care not to damage any surrounding components.
Step 5: Install the New Brake Line
Take the new brake line and attach it to the master cylinder, brake calipers, and other components using the brake line fittings. Make sure the fittings are securely tightened.
Step 6: Flare the Brake Line Fittings
Use a brake line flaring tool to flare the brake line fittings at the master cylinder, brake calipers, and other components. This will ensure a secure connection.
Step 7: Bleed the Brake System
Use a brake bleeding kit to remove any air from the brake system. This is an important step to ensure the brakes function properly.
Step 8: Reassemble and Test the Brake System
Reassemble the brake lines, making sure all fittings are securely tightened. Test the brake system by pressing the brake pedal and checking for proper function.
Precautions and Tips
Changing brake lines requires attention to detail and some mechanical skills. Here are some precautions and tips to keep in mind:
- Always refer to your vehicle’s owner’s manual for specific instructions on how to change brake lines.
- Make sure to wear protective gear, including gloves and safety glasses.
- Use a wire brush to clean any corrosion or debris from the brake line fittings.
- Use a rust remover to clean any rust from the brake line fittings.
- Use a tube bender to bend the brake line to the correct shape.
- Use a brake line flaring tool to flare the brake line fittings.
- Make sure to bleed the brake system after replacing the brake lines.
Conclusion
Changing brake lines is a crucial maintenance task that requires attention to detail and some mechanical skills. By following the steps outlined in this article, you can successfully replace your brake lines and ensure the safety and reliability of your vehicle’s braking system.
