4551003 Repair Kit, Brake Caliper Pin — MERITOR

The 4551003 Repair Kit, Brake Caliper Pin is a precision-engineered component designed to maintain the structural integrity of air disc brake systems. This part plays a critical role in the smooth movement of the caliper pins, ensuring consistent braking performance and preventing seizing under heavy-duty conditions. By using high-strength components, this kit helps maintain optimal braking geometry and system responsiveness.

4551003 is the OE-equivalent of the DAF 1522179, IVECO 93161029, IVECO 93161472, MERCEDES BENZ 000 420 04 76, MERITOR SJ1035, and MERITOR ST1153 products used in heavy commercial vehicle braking systems. This specific kit is developed to meet the rigorous standards required for fleet maintenance and heavy-duty service.

For workshop technicians, this repair kit provides an efficient solution for caliper maintenance. It is essential for servicing air disc brake calipers to ensure that pin movement remains free from friction or debris buildup. Regular inspection and replacement with high-grade components like this one can prevent more extensive brake system failures and ensure long-term reliability during routine service intervals.

Proper installation of this caliper pin kit is vital for vehicle safety. Technicians should ensure that all surfaces are clean and that the pins move freely within the assembly to prevent uneven brake wear or uneven braking forces in heavy commercial vehicles.
