Solution

1. Preparation

Gather all necessary tools and parts.
Tools Required:
- Wrench set
- Brake line cutter
- Flaring tool
- Brake line bender
- Torque wrench
- Brake fluid (DOT 3 or DOT 4)
- Safety goggles
- Gloves
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Remove the Damaged Brake Line

Locate the damaged brake line.
Use a wrench to disconnect the line from the brake caliper or master cylinder.
Carefully cut the damaged section of the brake line using a brake line cutter.
Remove any retaining clips or brackets that hold the brake line in place.

3. Prepare the New Brake Line

Measure the length of the old brake line to cut the new brake line to the same length.
Use the brake line bender to shape the new brake line to match the original routing.
Use the flaring tool to create appropriate ends on the new brake line (double flare for most applications).

4. Install the New Brake Line

Position the new brake line in the same path as the old line, ensuring no sharp bends or kinks.
Secure the new line with any retaining clips or brackets previously removed.
Connect the new line to the brake caliper/master cylinder, ensuring a snug fit.

5. Bleed the Brake System

Fill the brake fluid reservoir with new brake fluid.
Begin bleeding the brake system starting from the farthest wheel from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal while opening and closing the bleeder valve to release air bubbles.
Repeat for all wheels until no air bubbles are present and the pedal feels firm.

6. Final Inspection

Check all connections for leaks.
Recheck fluid levels in the reservoir and top off if necessary.
