Solution

1. Preparation

Gather Tools and Parts: Ensure you have all necessary tools and replacement parts ready.
Safety Precautions: Park the vehicle on a level surface, engage the parking brake, and wear safety glasses and gloves.

2. Remove the Damaged Brake Line

Tools Required: Wrench set, brake line wrench, cutting tool (if necessary).
Locate the section of the brake line that is leaking.
Use a wrench to disconnect the brake line from the fittings at both ends carefully.
If the line is severely corroded or damaged, use a cutting tool to remove the affected section.

3. Install the New Brake Line

Tools Required: Brake line bending tool, flare tool (if creating new ends), brake line wrench.
Cut a new piece of brake line to the required length.
Use the brake line bending tool to shape the line as needed to fit the vehicle.
If necessary, use the flare tool to create the proper fittings on the ends of the new line.
Connect the new brake line to the existing fittings, tightening securely with the brake line wrench.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old fluid.
Start at the farthest brake caliper from the master cylinder.
Attach the clear tubing to the bleeder screw and submerge the other end in a container filled with brake fluid.
Open the bleeder screw and have an assistant pump the brake pedal several times until fluid flows without air bubbles, then close the screw.
Repeat this process for each brake caliper in order: farthest to nearest.

5. Final Checks

Tools Required: Torque wrench (if applicable).
Inspect all connections for leaks.
Refill the brake fluid reservoir to the proper level with fresh brake fluid.
If applicable, torque the fittings to manufacturer specifications.
