Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel, rag
Open the hood and locate the brake fluid reservoir.
Wipe the area around the reservoir cap with a clean rag to prevent contaminants from entering.
Remove the reservoir cap and check the fluid level; if low, fill with the recommended brake fluid (typically DOT 4 or as specified in the owner's manual).
Replace the cap securely.

3. Inspect Brake Lines and Components

Tools Required: Socket set, flashlight
Visually inspect the brake lines from the master cylinder to the brake calipers for any signs of wear or leaks.
Check the brake calipers and wheel cylinders for leaks; if any are found, replace the damaged components.
Inspect brake pads for wear; replace if they are worn down to the indicator.

4. Test the Brake System

Tools Required: Brake bleeder kit (if applicable)
If the brake fluid was low, bleed the brake system to remove air bubbles. Start from the brake furthest from the master cylinder (usually the rear passenger side) and work your way to the closest.
Recheck the brake fluid level in the reservoir and ensure it is filled to the appropriate level.

5. Reset the Warning Light

Tools Required: OBD-II scanner (if applicable)
If the warning light remains on after addressing the issue, connect an OBD-II scanner to the vehicle and clear any stored codes related to the brake system.
Start the vehicle and check if the warning light has turned off.
