4121002 Spring, Brake Caliper Mechanism

The 4121002 Spring serves as a critical component within the brake caliper mechanism, providing the necessary tension and positioning for reliable air disc brake operation. This high-strength component is engineered to withstand the rigorous thermal and mechanical stresses typical of heavy commercial vehicle braking systems.

This product is specifically developed for compatibility with several heavy-duty vehicle models, including VOLVO FH13, FH16, FM13, FM12, FM11, FM10, FMX, VHD, VNL, B13R, B11R, and NH12 series, as well as MACK Granite and Pinnacle. It also serves MACK and VOLVO heavy-duty engine configurations such as D13A, D13B, D13C, D16C, D16E, D16G, D12C, D12D, D11A, D11B, MP7, and MP8. 4121002 is the OE equivalent of the required spring used in these high-performance braking systems.

For workshop technicians and fleet managers, this component ensures the precise mechanical movement required during braking cycles. Maintenance of the caliper mechanism with high-grade parts like this spring helps prevent system malfunctions and maintains optimal braking response. When replacing parts in the air disc brake system, always verify compatibility with the specific vehicle chassis and engine model to ensure seamless integration.
