What happens when the brake pads are worn?

When the brake pads wear down to a specific thickness, the wear lead sensor will make contact with the rotor. This typically creates a squealing or grinding noise, signaling that it's time to replace the brake pads.

How do these sensors protect my rotors?

By providing an early warning of worn brake pads, these sensors allow you to replace them before they wear completely away. This prevents the metal backing plate of the brake pad from grinding directly against the rotor surface, which can cause severe damage.

Are these sensors specific to certain brake pad types?

These wear lead sensors are designed for use with FMSI pad number D1897. It's important to ensure your brake pads are compatible with this number for the sensors to function correctly.

Product Details

This product includes the EBC front brake wear lead sensors for your Audi A4. These sensors are a critical component designed to alert you when your brake pads are getting low, helping to prevent costly damage to your rotors.

When your brake pads wear down to a certain point, this sensor will make contact, often creating a squealing noise. This is your signal to replace the brake pads before they wear completely away and cause metal-on-metal contact with the brake rotor. This simple sensor can save you a lot of money on rotor replacement down the line.
