4151053 Bolt, Brake Caliper Pin — VOLVO

This high-strength component serves as a critical fastening element within the air disc brake caliper system. Designed to maintain precise positioning and structural integrity under heavy-duty braking loads, it ensures the consistent operation of the caliper assembly. The part is manufactured using high-grade materials to withstand the rigorous mechanical stresses typical of heavy commercial vehicle braking environments.

4151053 is the OE-equivalent bolt, brake caliper pin used in VOLVO (8550881), MERITOR (SJ2021, SJ4021), and ALEXANDER DENNIS (655377-10) systems, including compatibility with models such as DENNIS LISA. This part ensures seamless integration with existing brake hardware to maintain optimal safety standards.

Workshop technicians should ensure that the caliper pin bolt is inspected for any signs of wear or deformation during routine maintenance. When replacing the component, verify that the mounting surfaces are clean and that the torque specifications are strictly followed to ensure proper assembly and long-term reliability of the braking system.

Regular inspection of the caliper pin assembly is essential for preventing irregular brake wear or caliper misalignment. This part is engineered to meet strict industrial standards for durability and precision in heavy-duty applications.
