How do these brake wear leads work?

These sensors make contact with the rotor surface once the brake pad material has worn down. This contact triggers a warning light on your dashboard or an audible squeal, alerting you that it's time to replace your brake pads.

Why is it important to replace brake pads when the wear leads activate?

Activating the wear leads means your brake pads are very thin. Continuing to drive can cause the metal backing plate of the pad to grind against the rotor, which can severely damage the rotor and lead to more expensive repairs.

Does this kit include everything needed to install the wear leads?

This kit includes the rear brake wear lead sensors. You will typically need to reuse the existing wiring harness from your old sensors or ensure your vehicle's wiring is compatible for connection.

About this part

Product Details

This is a set of rear brake wear lead sensors for your 2009-2010 BMW Z4 3.0L. These small but important parts are designed to alert you when your brake pads are getting thin and need replacing. They work by making contact with the rotor surface once the pad material has worn down to a certain point, creating an audible squeal or a warning light on your dashboard.

Using these wear leads is a smart way to protect your brake rotors from being damaged by metal-on-metal contact. If your brake pads wear down completely, the metal backing plate can grind against the rotor, causing deep grooves and potentially ruining the rotor. Replacing the pads before this happens is much cheaper than replacing both pads and rotors. This specific set is for the rear brakes and is designed to fit the FMSI D1433 pad number.
