3502022 KNORR-BREMSE SB6, SB7 Dust Blower, Brake Caliper Pin

The 3502022 component serves a critical role in maintaining the cleanliness and functionality of the braking system. As a dust blower for the brake caliper pin, it helps prevent debris accumulation that can lead to binding or uneven wear in the air disc brake assembly. This part is manufactured using heavy-duty grade materials to ensure long-lasting performance under demanding road conditions.

This product is designed to be compatible with KNORR-BREMSE SB6, SN6, SB7, SN7, and SK7 systems, as well as SCANIA and ZF hardware. 3502022 is the OE-equivalent part used in KNORR-BREMSE SB6 and SB7 braking systems. By maintaining precise tolerances, it ensures that the caliper pin remains free from contaminants, preserving the smooth movement of the caliper during deceleration.

For workshop technicians, this part is essential during routine brake inspections or caliper overhauls. It is recommended to check the condition of the dust blower and caliper pin whenever the braking system is serviced to prevent potential sticking or premature wear of the brake components. Ensuring a clean interface between the caliper and the mounting bracket is vital for consistent braking performance in heavy commercial vehicles.
