3551052 KNORR-BREMSE SN6, SN7, SK7 Repair Kit

The 3551052 brake caliper pin repair kit is engineered to maintain the precise movement and functionality of the air disc brake caliper system. Designed for heavy-duty service, this component ensures that the caliper remains properly aligned during braking-intensive operations, preventing uneven wear and ensuring consistent braking force.

3551052 is the OE-equivalent of the KNORR-BREMSE K001925, K028451 and MERCEDES BENZ 000 420 43 82 used in the KNORR-BREMSE SN6, SN7, SK7 and MERCEDES BENZ ATEGO, ATEGO 2, ATEGO 3. This precision-engineered kit meets the strict requirements of heavy commercial vehicle braking systems to provide reliable performance in demanding environments.

Workshop technicians should ensure that the caliper mounting surfaces are clean and free of debris before installing this repair kit. Proper lubrication of the pin during assembly is essential to prevent seizing and ensure smooth operation of the air disc brake mechanism. Regular inspection of these components is recommended during standard brake system maintenance intervals to prevent potential system failures.
