Understanding the Audi A4 B7 Brake Warning System
The brake warning system in your Audi A4 B7 is designed to alert you to potential problems before they escalate into major safety hazards.

How the Brake Pad Wear Sensor Works
Your Audi A4 B7 utilizes wear sensors embedded within the brake pads. These sensors are small wires that become exposed as the brake pad material wears down. When the pad reaches a critical thickness, the exposed wire makes contact with the brake rotor, completing a circuit and triggering the warning light on your dashboard. This system provides a clear indication that your brake pads need replacement.

Diagnosing the Audi A4 B7 Brake Pad Warning Light
While worn brake pads are the most common cause of the warning light, several other factors can contribute to this issue. These include:
- Low Brake Fluid: Insufficient brake fluid can trigger the warning light, indicating a potential leak in the braking system.

- ABS Issues: Problems with the Anti-lock Braking System (ABS) can also activate the warning light.
- Brake Master Cylinder Problems: Issues with the brake master cylinder can lead to a loss of brake pressure and trigger the warning light.
Checking Your Brake Fluid Level
Before assuming worn brake pads, check your brake fluid level. Locate the brake fluid reservoir under the hood and ensure the fluid level is within the recommended range.
