Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove the Damaged Brake Line

Tools Required: Wrench set, brake line cutter, bucket, brake fluid container
Locate the damaged section of the brake line.
Use a wrench to disconnect the brake line from the brake caliper and master cylinder.
Carefully cut the damaged section of the brake line with a brake line cutter. Allow any remaining brake fluid to drain into a bucket.

3. Install a New Brake Line

Parts Required: New brake line (ensure it is the correct length and diameter), brake line fittings
Measure and cut a new brake line to the appropriate length.
Attach the new brake line to the brake caliper and master cylinder using the previously removed fittings. Make sure to use new copper washers if applicable.
Secure the new brake line in place, ensuring it is routed away from any moving parts or heat sources.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, brake fluid
Fill the brake fluid reservoir with appropriate brake fluid (DOT 3 or DOT 4 as specified).
Use a brake bleeder kit or clear tubing to bleed the brake lines. Start with the wheel farthest from the master cylinder (usually the right rear).
Open the bleeder valve on the brake caliper and have an assistant pump the brake pedal until fluid flows without bubbles. Close the valve and repeat until all lines are bled.
Check the brake fluid level throughout the process and top off as necessary.
