Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake for safety.

2. Retrieve and Document Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Record all error codes related to the braking system for reference.

3. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).

4. Examine Brake Components

Remove the wheel to gain access to the brake assembly.
Inspect brake pads for thickness (minimum 3mm recommended) and check for uneven wear.
Check rotors for scoring or warping; replace if necessary.

5. Test Brake Pedal Switch

Use a multimeter to test the continuity of the brake pedal switch.
Press the brake pedal and check for a change in resistance; replace the switch if it fails.

6. Clear Codes and Test Drive

Use the OBD-II scanner to clear error codes from the vehicle's memory.
Perform a test drive to ensure brakes function correctly and monitor for the return of warning lights.
