EBC 06-09 BMW Z4 3.0 Si Front Wear Leads

These EBC brake wear sensor leads are designed to give you an early warning when your front brake pads are getting thin. They work by making contact with the rotor surface once the pad material has worn down to a specific point, triggering a warning light on your dashboard. This helps you avoid the costly damage that can occur if your brake pads wear down completely to the metal backing plate, which grinds away at your rotors.

The sensor itself is a small, durable piece that attaches to your brake pad. When the pad wears down, the sensor makes contact with the rotor, completing a circuit and illuminating your brake warning light. It’s a simple but effective way to monitor your brake pad life and ensure you replace them before they cause further issues.
