What does it mean when the brake warning light comes on?

[StMariana]

Reasons for the brake warning light coming on: 1. Severe brake pad wear - Brake pads come in two types: those with wear sensors and those without. When pads with sensors wear down to their limit, the sensor circuit completes and triggers the warning light; 2. Low brake fluid level - Brake fluid plays a crucial role in the braking system. When the fluid level drops too low (often due to leaks or normal wear), it can activate the warning light; 3. Other factors like brake system leaks can also trigger the light. If the brake warning light illuminates while driving, reduce speed gradually and pull over safely to inspect the system immediately.
