Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather all necessary tools and parts for the repair.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 4).
3. If fluid is contaminated or dark, perform a brake fluid flush.
4. Reinstall the reservoir cap securely.

3. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check rotors for scoring or excessive wear; replace if necessary.
4. Inspect brake calipers for leaks or damage; replace if any issues are found.

4. Repair or Replace Brake Lines

Sub-steps:
1. Trace brake lines for any signs of wear, corrosion, or leaks.
2. If damaged, use a line cutter to remove the affected section.
3. Install new brake lines using appropriate fittings and torque specifications (typically around 12-15 ft-lbs).
4. Bleed the brake system to remove air.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the brake warning message is illuminated.
Perform a test drive in a safe area to ensure brakes function properly.
