6402500040 is a genuine Wabco disc brake part, sold by Pro Gear and Transmission. In an air disc brake the rotor, the pads that clamp it and the caliper that carries those pads work together as one system. A big difference between the inner and outer pad on one rotor points to a caliper that is not sliding freely. A sticking caliper can make pads look worn out when the real fault is the caliper, so trace uneven wear to its cause before you fit new friction. Call us with your brake details to confirm this is the part you need.
