3551061 KNORR-BREMSE SL7, SM7, ST7 Repair Kit

This specialized repair kit is essential for maintaining the structural integrity of the air disc brake caliper system. Designed as a high-strength component for heavy commercial vehicle braking systems, it ensures smooth piston movement and prevents binding during operation. The kit provides a reliable solution for workshop technicians performing routine maintenance or complex repairs on braking hardware.

3551061 is the OE equivalent of the KNORR-BREMSE K012912 brake caliper pin repair kit used in KNORR-BREMSE SL7, SM7, ST7 systems and MERCEDES BENZ ACTROS or AXOR vehicles. This product ensures compatibility with heavy-duty braking architectures requiring precise mechanical tolerances. By utilizing this kit, technicians can restore the original functionality of the braking assembly without compromising safety standards.

During installation in the workshop, it is vital to verify the cleanliness of the caliper housing and ensure that the pin moves freely within its seat. This component is specifically designed for heavy commercial vehicle applications such as Mercedes Benz heavy trucks. Regular inspection of these pins is recommended to prevent uneven pad wear or uneven braking force caused by friction or debris buildup in the assembly.
