4551011 Dust Blower, Brake Caliper Pin - VOLVO

The heavy-duty 4551011 Dust Blower, Brake Caliper Pin serves a critical role within the air disc brake caliper system. Designed to protect moving parts from environmental debris, this component ensures the smooth and reliable operation of the brake caliper pin assembly. It is manufactured using high-strength components to withstand the rigorous vibrations and thermal cycles typical in heavy commercial vehicle environments.

This specific part is the OE-equivalent of the DAF 1522161, MERITOR SP8567, and VOLVO 270531 or 3090938 components used in heavy commercial vehicle braking systems. It is fully compatible with systems from DAF, MERITOR, and VOLVO. The precise engineering of this dust blower ensures that the caliper pin remains protected against dust and moisture ingress, maintaining optimal braking performance.

For workshop technicians, replacing the dust blower during brake service is essential for preventing caliper seizure and ensuring consistent braking force. When performing maintenance on DAF or VOLVO heavy-duty trucks, always verify the fitment against the original technical specifications. Regular inspection of the brake caliper components helps prevent premature wear and ensures long-term system reliability during heavy-duty operations.
