Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid tester, basic hand tools.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Wear safety goggles and gloves.

2. Address Fault Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Power on the scanner and navigate to the "Read Codes" section.
3. Record all retrieved brake system-related codes.
4. Research each code to understand its specific implications and possible issues.

3. Inspect Brake Fluid System

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; top off with manufacturer-recommended brake fluid if low.
3. Inspect the fluid for contamination or discoloration. If contaminated, flush the brake fluid system.

4. Visual Inspection of Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if below manufacturer specifications.
3. Check rotors for scoring or warping; replace if damaged.
4. Examine calipers for leaks or sticking; repair or replace as necessary.

5. Test Electrical Connections

Sub-steps:
1. Locate the brake system sensors and connectors.
2. Use a multimeter to test for continuity and proper voltage at each connector.
3. Repair or replace any damaged wiring or connectors as needed.

6. Clear Codes and Test Drive

Sub-steps:
1. Use the OBD-II scanner to clear any fault codes from the system.
2. Perform a test drive to monitor brake performance.
3. Re-scan for error codes after the test drive to ensure no new codes have appeared.
