Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a flat surface and securely supported.
Disconnect the battery to prevent accidental activation of electrical components.

2. Connect OBD-II Scanner

Plug the OBD-II scanner into the vehicle's diagnostic port located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to access the brake system codes.

3. Analyze and Address Fault Codes

Record any error codes retrieved from the scanner.
Research each fault code to identify the specific issue related to the brake system.
If the code indicates a specific component failure (e.g., ABS sensor), proceed to inspect or replace that component.

4. Inspect Brake Components

Check brake fluid levels; refill with manufacturer-recommended brake fluid if low.
Inspect brake lines for leaks, cracks, or corrosion, replacing any damaged sections.
Examine brake pads for wear – replace if the thickness is below manufacturer specifications.
Inspect brake rotors for scoring or warping and replace if necessary.

5. Test Brake System Functionality

Reconnect the battery and perform a brake system functional test.
Ensure the brake warning lights are off, and the brake pedal has a firm feel.
Conduct a road test to confirm the brakes engage smoothly without unusual noises.
