The Brembo rear brake wear sensor for BMW 5 Series and related models (2000–2003) including M5 and Z8 applications monitors pad thickness and signals when replacement is necessary. Made to OE specifications for original-equivalent performance, Brembo advises replacing the sensor with brake pads. The sensor uses high-quality wiring and connectors to resist heat and weather for durable electrical function.
