Brake Pad Wear Sensors

When a brake pad incorporating a brake pad wear sensor is approximately 75% worn, the sensor wire within the pad material is worn through and the brake pad wear sensor goes open circuit. When the instrument cluster detects the open circuit, it illuminates the amber LED (light emitting diode) in the brake warning indicator, displays an appropriate warning in the message center and sounds a warning chime.

Refer to Instrument Cluster (Description and Operation).

NOTE: A new pad wear sensor lead must be fitted whenever the brake pads are changed, irrespective of the brake pad warning sensor being triggered.

The brake pad wear sensor is wired in series with a wear sensor on the RH (right-hand) rear brake and the instrument cluster. If the thickness of one of the brake pads connected to a wear sensor decreases to a predetermined limit, the instrument cluster illuminates the brake warning indicator.
