Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe working environment.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (typically near the back of the engine bay).
Carefully remove the reservoir cap.
Inspect the fluid level; if low, add brake fluid (DOT 3 or as specified in the owner's manual) to the appropriate level.
Replace the cap securely.

3. Inspect Brake Lines and Hoses

Visually inspect all brake lines and hoses for signs of leaks, cracks, or damage.
If any leaks are found, replace the damaged lines or hoses.
Ensure all connections are tight and secure.

4. Test Brake Components

Remove the wheel and inspect the brake pads for wear; replace if thickness is less than 3mm.
Check the brake rotors for grooves or warping; replace if necessary.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically 80-100 lb-ft).

5. Reset Warning Light

If no issues are found, use an OBD-II scanner to clear any fault codes related to the brake system.
Turn the ignition on and off to ensure that the warning light resets.

6. Test Drive

Take the vehicle for a short test drive to ensure the brakes function properly and the warning light does not reappear.
