Understanding the BMW 5 Series Brake Pad Warning System
The brake pad warning light system in your BMW 5 Series is designed to alert you when the brake pads have worn down to a point where they need to be replaced. Ignoring this warning can lead to further damage to the braking system, compromising safety.
How the Warning Light Works
The system typically uses sensors embedded within the brake pads themselves. These sensors monitor the thickness of the brake pad material. When the pad material wears down to a predetermined level, the sensor triggers the warning light on your dashboard. The light usually appears as a yellow or red symbol, often depicting a circle with brake pad outlines. If you see this symbol illuminated, it’s time to inspect your brake pads. You can also learn more about the specific symbols by checking our guide on BMW brake pad warning light symbol.
