3556029 SL7, SM7, ST7 Optional and Dust Bellow

The brake caliper tappet serves a critical role in maintaining the integrity of the braking system by protecting moving components from external contaminants. This component is designed to provide a durable seal and ensure smooth operation of the air disc brake assembly under demanding heavy-duty conditions. By utilizing high-strength components, it helps maintain consistent braking pressure and prevents premature wear of the caliper mechanism.

3556029 is the OE-equivalent component used in KNORR-BREMSE SL7, SM7, and ST7 systems. This part is specifically engineered to meet the rigorous requirements of heavy commercial vehicle braking hardware, ensuring seamless integration with existing pneumatic systems. It provides a precise fit for workshop technicians performing maintenance or repairs on specific brake caliper assemblies.

For workshop technicians specializing in heavy commercial vehicle service, this part offers a reliable solution for maintaining braking system efficiency. Regular inspection of the dust bellows and tappet components is essential during routine brake service to prevent dust or debris from entering the caliper system. Proper installation ensures that the braking force remains consistent and the system operates within specified technical tolerances.
