Brembo 12-21 BMW 228i/228i xDrive/230i/230i xDrive/320i/320i xDrive Brake Wear Sensor - Front

The wiring and connectors on this Brembo brake wear sensor are built to handle high heat and tough weather, which is important because they're right there near the brakes. This sensor is designed to monitor the thickness of your front brake pads. When the pads wear down to a minimal thickness, it sends a signal to your dashboard, letting you know it's time to replace them. This helps prevent damage to your brake rotors, which can happen if you drive too long on worn-out pads.

This sensor is made to OE specifications, meaning it should perform just like the original part that came on your BMW. Brembo recommends changing these sensors every time you replace your brake pads to ensure you always have an accurate warning system. This part fits a wide range of BMW models, including the 2 Series, 3 Series, and 4 Series, as well as M2, M3, and M4 vehicles.
