The Brembo OE brake pad wear sensor is an OE-spec replacement for specified BMW applications (01–05 325xi, 01–06 330Ci/330i/330xi, and 01–06 M3). It monitors pad thickness and sends a warning when pads reach minimum serviceable thickness. Manufactured to OEM standards, the sensor features durable wiring and connectors that resist high heat and harsh weather; Brembo recommends replacing the sensor with each brake pad change.
