Brake Wear Sensor - Front is an electrical component in the front braking system of the Discovery 3.

The sensor is embedded in the brake pad and makes contact with the brake disc rotor when the pad material has worn to its minimum safe thickness. This triggers a warning on the instrument panel, indicating that the front brake pads require immediate inspection and replacement.

Frequently asked questions

What does the front brake wear sensor do on a Discovery 3?
The front brake wear sensor triggers a dashboard warning when the front brake pads reach minimum thickness. It sits in the front brake pad and contacts the disc as the pad wears down, signalling the pads need replacing. Part number SEM000024 on the Discovery 3.
How many front brake wear sensors are needed for a Discovery 3?
Typically one front brake wear sensor is fitted per axle on the Discovery 3, usually on a single front caliper rather than both. Check your existing setup before ordering, as it's common to renew the sensor whenever the front pads are changed.
Why does the front brake wear sensor need replacing?
The front brake wear sensor is designed to be worn through as the pads reach their limit, breaking its loop to trigger the warning. Once triggered or disturbed during a pad change it won't reset, so it's typically replaced alongside a new set of front brake pads.
