Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Damaged Brake Line

Tools Required: Wrenches (various sizes), line wrenches, cutting tool, brake line bending tool.
Locate the leaking section of the brake line.
Use a line wrench to carefully disconnect the brake line at both ends (master cylinder and caliper or wheel cylinder).
If the line is severely corroded, use a cutting tool to remove the damaged section.

3. Install New Brake Line

Tools Required: Brake line bending tool, tubing cutter, flaring tool.
Cut a new brake line to the appropriate length using a tubing cutter.
Use the flaring tool to create proper flares on the ends of the new brake line.
Bend the new brake line to match the original routing.

4. Connect the New Brake Line

Attach the new brake line at both ends using the line wrench to ensure a secure fit.
Ensure the connections are tight but avoid overtightening, which can damage the fittings.

5. Refill Brake Fluid and Bleed the System

Tools Required: Brake fluid, bleed kit, container for old fluid.
Refill the brake fluid reservoir with the appropriate type of brake fluid as specified in the owner's manual.
Bleed the brake system to remove any air trapped in the lines. Start from the farthest wheel from the master cylinder and work your way to the closest.
