Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Inspect Brake Pads and Rotors

Lift the front and rear of the car using a jack and secure with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for wear; replace if they are less than 3mm thick.
Check the condition of the rotors for scoring or warping; replace if necessary.

4. Check Brake Lines and Master Cylinder

Visually inspect the brake lines for cracks, leaks, or corrosion.
If any leaks are found, replace the damaged sections of the line.
Inspect the brake master cylinder for leaks or fluid contamination; replace if faulty.

5. Reset Brake Warning Light

If all components are in good condition, use the OBD-II scanner to clear any fault codes from the system.
Turn the ignition to the "On" position without starting the engine to reset the brake warning light.
