4051022 Dust Blower, Brake Caliper Pin WABCO

The 4051022 component serves as a critical element within the air disc brake caliper system, specifically functioning as a dust blower to ensure the smooth operation of the brake caliper pin. Designed to withstand heavy-duty industrial environments, this part plays a vital role in protecting the moving parts of the braking system from external contaminants and debris. By maintaining a clean environment around the caliper pin, it ensures consistent braking performance and prevents premature wear.

4051022 is the OE-equivalent of the WABCO 12 999 746VT Dust Blower used in DAF, MACK, RENAULT TRUCKS, and VOLVO heavy commercial vehicles. This high-strength component is also fully compatible with WABCO PAN 19 DOUBLE and PAN 22 DOUBLE systems. It serves as a direct replacement for OEM references including DAF 1440505, MACK 261112999746VT, RENAULT TRUCKS 5001858722, RENAULT TRUCKS 7421454874, and VOLVO 21454874.

For workshop technicians and fleet managers, this part offers precise fitment and ease of assembly within the braking system. Regular inspection of the dust blower and caliper pin area is recommended during routine brake service to ensure that no debris accumulation affects the mechanical movement. Maintaining these components helps prevent sticking calipers and ensures the long-term reliability of the vehicle's pneumatic braking-suspension hardware.
