Brake Calipers

When hydraulic pressure is supplied to the calliper, the brake pads move against the brake disc.

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 light emitting diode (LED) in the brake warning indicator, displays an appropriate warning in the message center and sounds a warning chime.

A sensor is fitted to the rear right and front left brake pads. The sensors are connected in series.

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.
