3502038 Dust Rubber, Brake Caliper Shaft

The 3502038 dust rubber is a critical component designed to protect the brake caliper shaft from environmental contaminants. By sealing the internal mechanism, it ensures the smooth movement and long-term durability of the air disc brake system. This part is engineered using high-strength components to withstand the rigorous vibrations and temperature fluctuations typical in heavy commercial vehicle braking systems.

This product is an OE-equivalent part used in KNORR-BREMSE systems. It serves as a vital protective element within the Air Disc Brake Caliper assembly, ensuring that the caliper shaft remains free from dust and debris. The precise Ø 74 mm diameter specification guarantees a secure fit and optimal sealing performance during operation.

For workshop technicians, this dust rubber provides an essential maintenance solution for maintaining braking system integrity. Regular inspection of these rubber components is recommended to prevent premature wear of the caliper shaft. Ensuring a clean and well-sealed assembly helps prevent system malfunctions and maintains consistent braking performance in heavy-duty service environments.
