3556003 SB5, SN5 Brake Caliper Cover

The 3556003 brake caliper cover serves as a vital protective component within the air disc brake system. This part is engineered to shield the internal caliper mechanisms from external contaminants, ensuring the longevity and consistent performance of the braking assembly in demanding environments.

This component is the OE-equivalent cover used in KNORR-BRESE SB5 and SN5 systems for MAN TGL and TGM heavy commercial vehicles. It provides a precise fit to maintain the structural integrity of the braking-suspension system during intense operation.

Workshop technicians should ensure that the caliper surface is clean and free of debris before installing this cover. It is designed for seamless assembly within the SB5 and SN5 series, providing a reliable seal that supports regular maintenance intervals for heavy-duty truck fleets. Proper fitment prevents dust and moisture ingress, preserving the mechanical function of the caliper components.

Using high-strength components like this cover helps prevent premature wear of the internal piston and seals. It is essential for maintaining optimal braking performance in heavy commercial vehicle applications.
