Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Wrench set
- Brake line flaring tool (if making new lines)
- Brake line cutter
- Brake fluid
- Funnel
- Clean rags
- Safety goggles and gloves
Safety Warnings:
- Always wear safety goggles and gloves to protect from brake fluid.
- Ensure the vehicle is securely lifted and supported before working underneath.

2. Remove the Damaged Brake Line

Lift the Vehicle:
- Use the jack to lift the car and securely place it on jack stands.
Locate the Damaged Brake Line:
- Identify the section of the brake line that is leaking.
Disconnect the Brake Line:
- Use the appropriate wrench to loosen and disconnect the brake line fittings at both ends. Use a catch pan to collect any leaking brake fluid.
Cut the Damaged Section:
- Use a brake line cutter to cut out the damaged portion of the brake line, ensuring clean cuts for proper fitting.

3. Install New Brake Line

Measure and Cut New Brake Line:
- Measure the length needed for the new brake line. Cut a new brake line from a coil of brake line tubing.
Flare the Ends:
- Use a brake line flaring tool to create flared ends on the new line for a proper fit.
Install the New Brake Line:
- Attach the new brake line to the existing brake lines and fittings, ensuring a tight seal. Use a wrench to secure the connections.

4. Refill Brake Fluid

Refill the Brake Fluid Reservoir:
- Open the brake fluid reservoir cap and use a funnel to refill it with the appropriate brake fluid (usually DOT 3 or DOT 4).
Bleed the Brake System:
- Starting from the brake furthest from the master cylinder, bleed the brakes to remove air. Repeat for all brakes until the pedal feels firm.

5. Test the Brake System

Check for Leaks:
- Inspect all connections for leaks after the brake system is bled.
Test Drive:
- Conduct a test drive to ensure brakes are functioning properly and there are no fluid leaks.
