4120014 Piston, Brake Caliper Pin

The 4120014 piston serves a critical function within the air disc brake caliper system, ensuring smooth and reliable movement of the caliper pin. This high-strength component is engineered to withstand the rigorous demands of heavy commercial vehicle braking cycles, maintaining structural integrity under high-pressure environments.

This part is the OE equivalent of the MERITOR piston used in the MERITOR DX 175 system. It is designed to meet strict technical tolerances to ensure seamless integration with existing braking hardware. By utilizing heavy-duty grade materials, this component provides the necessary stability for heavy-duty service environments.

For workshop technicians, this part offers a reliable solution for maintaining brake caliper functionality. Regular inspection of the piston and caliper pin assembly is essential to prevent uneven wear or system drag. This component ensures that the braking force is applied consistently and efficiently throughout the service interval.

Proper installation requires adherence to standard heavy commercial vehicle maintenance protocols to ensure optimal system response and safety.
