If the yellow warning light indicating brake wear (central circle with dashed semicircles on the sides) illuminates on the instrument panel, it means that the minimum thickness of the brake pads has been reached, causing the wear sensor circuit to open: in this case, both the pads and the sensor must be replaced.

The sensor is located on the edge of the inner pad of the left front wheel or the right rear wheel, and it is sufficient to lever it out with a screwdriver; then follow the cable to reach the connector (black plastic) located near the blue speed sensor connector.

If the warning light remains on after replacing the front pads and sensor, then it is the rear sensor: to confirm this before replacing it, disconnect the connector and join the contacts of the wiring connector to simulate the sensor replacement and restore continuity; when the ignition is turned on, the light will turn off after about 20 seconds.

Subsequently, proceed with the replacement of the pads and sensor.
