Solution

1. Preparation

Gather tools including a brake fluid tester, OBD-II scanner, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety Warning: Always wear safety glasses and gloves when working on the braking system.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and visually check the fluid level. It should be between the "MIN" and "MAX" marks.
If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).

3. Inspect for Leaks

Visually inspect the brake lines, calipers, and master cylinder for any signs of leakage.
Clean any existing leaks with brake cleaner and dry the area.
If leaks are found, replace the damaged components (e.g., brake lines, calipers).

4. Brake Pad and Rotor Inspection

Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if they are below 3mm.
Check the rotors for grooves or warping; replace if necessary.
Reassemble the wheel after inspection.

5. Electrical Connections Check

Locate the brake light switch; ensure it is properly connected.
If necessary, test the switch using a multimeter for continuity.
Replace the switch if it’s faulty.

6. Clear Trouble Codes

Use the OBD-II scanner to clear any diagnostic trouble codes found during the initial check.
Restart the vehicle and check if the brake warning light remains illuminated.
