Solution

1. Preparation

Gather all necessary tools and parts.
Safety gear: gloves and safety glasses.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.

2. Gather Tools and Parts

Tools Required:
- Wrench set
- Brake line flaring tool
- Tube cutter
- Brake line bending tool
- Brake line pressure tester
- Torque wrench
- Jack and jack stands
Parts Required:
- Replacement brake line (specific to model)
- Brake line fittings (if necessary)
- Brake fluid

3. Remove Damaged Brake Line

Lift Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Locate Leaking Section:
- Trace the brake line from the master cylinder to the affected area.
Disconnect Brake Line:
- Using the appropriate wrench, carefully disconnect the leaking brake line from both ends (master cylinder and caliper/wheel cylinder). Be prepared for some brake fluid to leak out.
Cut Out Damaged Section:
- Use a tube cutter to remove the damaged section of the brake line.

4. Install New Brake Line

Prepare New Brake Line:
- Cut the new brake line to the required length and use a brake line flaring tool to create proper flares on both ends.
Bend and Route the Line:
- Use a brake line bending tool to shape the new line to match the original routing. Ensure it does not rub against any moving parts.
Connect New Brake Line:
- Attach the new brake line to the master cylinder and brake caliper/wheel cylinder. Ensure fittings are secure but do not overtighten.

5. Bleed Brake System

Fill Brake Fluid Reservoir:
- Fill the brake fluid reservoir with the recommended brake fluid.
Bleed the Brakes:
- Begin at the wheel furthest from the master cylinder (typically the rear passenger side) and work your way to the closest (front driver side). Use a helper or a one-person brake bleeder tool to remove air.

6. Final Checks

Inspect all connections for leaks after bleeding.
Recheck brake fluid levels and top off as necessary.
