4051012 WABCO Compatible Dust Blower, Brake Caliper Pin

The 4051012 Dust Blower, Brake Caliper Pin plays a critical role in maintaining the integrity of the air disc brake caliper assembly. By preventing debris accumulation within the mechanical movement of the caliper pin, this component ensures consistent braking performance and prevents premature wear in heavy-duty environments.

4051012 is the OE-equivalent of the MERCEDES BENZ 002 420 31 83 and WABCO 640 175 922 2 used in the MERCEDES BENZ and WABCO PAN 17 systems. This component is specifically designed to meet the rigorous demands of heavy commercial vehicle braking systems, ensuring seamless integration with existing hardware.

For workshop technicians, this part offers precise fitment and ease of assembly. Regular inspection of the dust blower and caliper pin assembly is recommended during routine brake system maintenance to ensure that external contaminants do not interfere with caliper movement. This part is essential for maintaining optimal service intervals and system responsiveness.

This high-strength component is engineered for heavy commercial vehicle applications, providing stability to the air disc brake system. It is designed to handle high-stress environments typical of truck and bus braking architectures.
