Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shocks.
Gather all necessary tools and parts.

2. Remove the Damaged Brake Line

Tools Required: Wrench set, brake line wrenches, line cutter, container for fluid.
Locate the leaking section of the brake line and mark it for replacement.
Use a line cutter to cut the brake line at both ends of the damaged section.
Wrench the fittings on both ends to remove the old line, being careful not to damage surrounding components.
Allow any residual brake fluid to drain into the container.

3. Install the New Brake Line

Tools Required: Brake line bending tool, flare tool, brake line wrenches.
Measure and cut the new brake line to the correct length, adding a bit of extra for bends.
Use the brake line bending tool to create any necessary bends for proper routing.
Flare the ends of the new line as needed to ensure a tight seal.
Install the new line by threading it into the existing fittings, tightening with the brake line wrenches.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container for old fluid.
Reconnect the negative battery terminal.
Fill the master cylinder reservoir with fresh brake fluid.
Begin bleeding the brakes from the furthest wheel from the master cylinder to the nearest, ensuring no air is trapped in the lines.
Repeat the process until the fluid runs clear without bubbles.

5. Test and Inspect

Recheck all fittings for leaks after bleeding.
Test the brake pedal feel before taking the vehicle on the road.
Conduct a short test drive to ensure proper brake function.
