The Wabco 4006120510 is a 2-sensor, 2-modulator Integrated Anti-lock Brake System (IABS) retarder control unit for heavy-duty truck and trailer applications. The 2S/2M designation identifies the system configuration: two wheel-speed sensors and two brake modulator channels, the standard setup for basic axle-end ABS coverage. This Wabco IABS retarder component integrates ABS logic with retarder control to coordinate wheel-slip management during engine braking and service braking events.
