Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Engage the parking brake and wear safety gloves.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and check the fluid level against the "Min" and "Max" markings.
If low, add manufacturer-approved brake fluid (DOT 3 or DOT 4 depending on model).

3. Inspect for Leaks

Visually inspect brake lines, calipers, and hoses for any signs of leaks or damage.
If any leaks are found, replace the affected components and ensure all connections are tight.

4. Brake Pad and Rotor Inspection

Remove the wheel to access the brake caliper and rotor.
Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
Check the rotor surface for scoring or excessive wear; replace if necessary.

5. Reset the Brake Warning Light

If all components are in good condition and no issues are found, the warning light may need to be reset.
Disconnect the negative battery terminal for a few minutes and reconnect it to clear codes.
