Solution

1. Preparation

Tools Required: Jack and jack stands, brake line wrench set, brake fluid, fluid catch pan, wire brush, rust inhibitor, safety goggles, gloves.
Raise the vehicle securely using a jack and jack stands to access the brake lines.

2. Remove Corroded Brake Lines

Sub-steps:
1. Identify the corroded sections of brake lines.
2. Use a wire brush to clean any loose rust around the connection points.
3. Use a brake line wrench to disconnect the corroded sections from the fitting.
4. Carefully remove the old brake lines, ensuring to capture any leaking brake fluid in the fluid catch pan.

3. Install New Brake Lines

Sub-steps:
1. Measure and cut new brake line sections to the required lengths.
2. Use a brake line flaring tool to create the necessary flare on the ends of the new lines.
3. Install the new brake lines, connecting them to the existing fittings, ensuring all connections are tight but not over-tightened.
4. Route the brake lines away from any potential sources of damage and secure them with brackets if necessary.

4. Bleed the Brake System

Sub-steps:
1. Fill the master cylinder reservoir with new brake fluid.
2. Starting from the wheel farthest from the master cylinder, attach a brake bleeder kit to the bleeder screw.
3. Open the bleeder screw and have an assistant pump the brake pedal until fluid flows without bubbles.
4. Repeat for all wheels in the correct order (farthest to closest).
5. Check and top off the brake fluid level in the reservoir.
