Brembo brake pad wear sensor for BMW 525i (2001–2003), 528i (2000) and 540i (2000–2003) models provides electronic monitoring of brake pad thickness and sends a warning when pads are at minimal thickness. Made to OE specifications to match the original sensor, it should be replaced with the pads; high-quality wiring and connectors resist high heat and harsh weather for dependable service.
