4120015 Piston, Brake Caliper Pin

This piston is a critical component within the Air Disc Brake Caliper system, designed to provide precise movement and pressure within the braking mechanism. It is manufactured using heavy-duty grade materials to ensure long-term durability and stability under high-stress operating conditions in heavy commercial vehicles.

4120015 is the OE-equivalent piston, brake caliper pin used in the MERITOR DX 175 system. This component is engineered to meet strict technical standards to maintain consistent braking force and system responsiveness. Its integration into the braking assembly ensures that the mechanical movement of the caliper remains smooth and predictable.

Workshop technicians should ensure that the piston surface and surrounding seals are inspected during installation to prevent any issues with braking performance. Regular maintenance of the brake caliper pin assembly is essential for maintaining optimal safety in heavy commercial vehicles. This part is designed for easy assembly and direct replacement within compatible MERITOR braking hardware systems.
