Solution

1. Preparation

Gather necessary tools and parts.
Ensure you are wearing safety glasses and gloves.
Park the vehicle on a level surface and engage the parking brake.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).

3. Inspect Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake calipers and pads.
Inspect the brake pads for thickness; replace if they are below 3 mm.
Check the rotors for scoring or warping; replace if necessary.

4. Check for Leaks

Examine brake lines and hoses for leaks or damage.
If leaks are found, replace the affected components and bleed the brake system to remove any air.

5. Test Brake Light Switch

Locate the brake light switch near the brake pedal.
Disconnect the connector and test for continuity with a multimeter while pressing the brake pedal.
Replace the switch if it is faulty.

6. Clear Codes and Test Drive

After repairs, clear any stored DTCs using the OBD-II scanner.
Test drive the vehicle to ensure the brake warning light is no longer illuminated and brakes function correctly.
