Wabco 6401950810 is a left-hand (LH) caliper, a genuine Wabco brake part from Pro Gear and Transmission. The caliper clamps the brake pads against the rotor, and it has to slide freely on its guides so both pads apply evenly.
A caliper that has stopped sliding loads one pad harder than the other, so the inner and outer pads wear unevenly and the rotor heats unevenly. Torn or missing guide boots let dirt and water into the sliding mechanism, which is a common way a caliper ends up seizing. This is the left-hand (driver's side) caliper, so order the side that matches the wheel end you are working on, and call us to confirm proper fit.
