Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working.

2. Remove the Damaged Brake Line

Tools Required: Wrench set, line wrenches, brake line cutter.
Locate the damaged section of the brake line.
Use the line wrench to carefully loosen the fittings at both ends of the damaged line.
Use the brake line cutter to cut the line if needed to remove it entirely.
Ensure to catch any leaking brake fluid with a container.

3. Install New Brake Line

Tools Required: Flare nut wrench, tubing bender (if needed).
Measure and cut the new brake line to the appropriate length, ensuring it fits without kinks.
Use a tubing bender to shape the new line to match the original layout.
Install the new line by threading it into the fittings and tightening securely with the flare nut wrench.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, brake fluid.
Fill the master cylinder reservoir with fresh brake fluid.
Begin bleeding the brakes from the farthest wheel from the master cylinder, typically the rear passenger side.
Use the brake bleeder kit to remove air bubbles from the system until clean fluid flows out.
Repeat for all wheels in the appropriate sequence.

5. Final Checks

Reconnect the battery.
Start the engine and check for any leaks around the new brake line connections.
Test the brake pedal for firmness before driving.
