4001003 Pin, Brake Caliper Pin

The 4001003 Brake Caliper Pin is a critical component within the air disc brake system, designed to ensure the precise positioning and smooth movement of the caliper. This high-strength component is engineered to withstand the rigorous demands of heavy commercial vehicle braking systems, providing consistent stability and durability under high-stress operating conditions.

This part is compatible with a wide range of heavy-duty vehicles including VOLVO (such as FH12, FH13, FM12, FM13, VNL, and FMX models), RENAULT TRUCKS (including Premium and Kerax series), DAF, and MACK. 4001003 is the OE equivalent of the high-performance braking hardware required for these specific engine configurations and vehicle architectures. It also serves various industrial applications involving brands like SCANIA, IVECO, and MAN.

For workshop technicians and fleet managers, maintaining the brake caliper pin is essential for preventing uneven wear or caliper binding. Regular inspection of the pin and its structural integrity during routine brake maintenance helps ensure optimal system response. When replacing these components, always verify the diameter specifications—in this case Ø 38 / 118 mm—to ensure a perfect fit within the existing caliper assembly.

Proper installation of this pin ensures that the braking force is applied evenly across the rotor. Given its role in heavy commercial vehicle safety, using high-strength grade materials is vital for long-term reliability in the field.
