3556006 SB6, SB7 Ø74mm Optional and Dust Bellow

This specialized brake caliper component plays a vital role in the air disc brake system of heavy commercial vehicles. Designed as an optional and dust bellow/tappet, it ensures the smooth movement of the caliper mechanism while protecting internal parts from external contaminants. Its robust construction is engineered to withstand demanding braking environments.

3556006 is the OE-equivalent brake caliper tappet used in Scania, Mercedes Benz, MAN, BPW, SAF, and Knorr-Bremse SB6/SB7 systems. This part is fully compatible with OEM specifications such as 09.801.02.63.0, 0980102630, II179320065, II304130065, 81.50822-6007, 81.50822-6022, 000 420 06 82, 000 420 39 82, 000 420 48 82, 3434380400, 1390429, 1746824, and 1759811.

Workshop technicians should perform regular inspections of the brake caliper assembly to ensure the dust bellow remains intact and functional. Proper installation of this Ø 74 mm component is essential for maintaining optimal braking performance and preventing system failure in heavy-duty trucks and buses. Always verify compatibility with the specific brake system architecture before assembly.

Maintaining high-strength components like this one helps prevent debris from entering the piston area, thereby extending the service life of the entire air disc brake assembly.
