4120002 Piston, Brake Caliper Pin

The precision-engineered piston plays a critical role in the air disc brake system, ensuring the smooth and reliable movement of the caliper mechanism. This component is manufactured with high-strength materials to withstand the rigorous thermal and mechanical stresses encountered during heavy-duty braking operations.

The 4120002 is the OE equivalent of the specialized brake caliper piston used in various heavy commercial vehicle applications. It is specifically designed to be compatible with VOLVO models such as FH13, FH16, FM12, and VNL, as well as MACK Pinnacle and Granite series. It also serves systems from MERITOR, DAF, and RENAULT TRUCKS. This part ensures the structural integrity of the braking system during intense service cycles.

For workshop technicians and fleet managers, this component is essential for maintaining optimal braking force and safety. When replacing the piston or caliper pin, it is vital to check the surrounding seals and hardware to ensure a perfect fit within the caliper assembly. Regular inspection of the braking system components helps prevent premature wear and maintains vehicle safety standards.

Maintenance of these critical parts ensures long-term reliability for heavy-duty trucks and buses. Consult your authorized distributor for technical-specific compatibility or further guidance on installation.
