K162565 is the Bendix iSense Wear Indicator Kit, a disc brake pad wear sensor kit. The sensor keeps watch on how much friction material is left on the pads of an air disc brake and alerts the driver before the pads are used up. A wear sensor is generally a single-use item, so it is usually replaced whenever the pads are serviced rather than reused. A sensor that has tripped or been damaged cannot report pad condition, and worn pads can go unnoticed until braking suffers. A genuine Bendix part from Pro Gear and Transmission.
