4051031 Dust Blower, Brake Caliper Pin

The heavy-duty Dust Blower and Brake Caliper Pin is a critical component within the air disc brake caliper system. Designed to maintain the precise movement of the caliper pin, this part ensures reliable braking performance by preventing debris buildup and ensuring smooth mechanical operation during high-stress driving conditions.

4051031 is the OE-equivalent of the WABCO 640 319 922 2 dust blower used in RENAULT TRUCKS, VOLVO, and WABCO MAXX 19 systems. This component is engineered to meet strict industrial standards for heavy commercial vehicles, ensuring seamless integration with existing brake hardware.

For workshop technicians, this part is essential during routine brake service or caliper overhauls. When replacing worn caliper pins or dealing with dust accumulation in the braking assembly, using high-strength components like this one helps prevent system sticking and maintains optimal braking force. Regular inspection of the dust blower and pin area is recommended during scheduled maintenance to ensure long-term reliability.

This product is specifically developed for the heavy commercial vehicle sector, providing a stable fitment for various truck and bus models that utilize these specific braking architectures.
