4502019 Piston, Brake Caliper Pin

This high-strength component plays a critical role in the air disc brake system, ensuring precise piston movement and consistent braking performance. Designed for heavy commercial vehicle applications, the piston is engineered to withstand demanding thermal and mechanical stresses during operation.

The 4502019 piston features a diameter of Ø 68 mm and is engineered to meet high-durability standards. It is compatible with various heavy-duty models including VOLVO FH12, FH13, FH16, FM11, FM12, FM13, FMX, VNL, VHD and B11R/B13R series. It also serves RENAULT TRUCKS (Magnum/Premium), MACK (Pinnacle/Granite), DAF, IVECO, and MAN applications. This 4502019 part is the OE equivalent of the standard components used in these specific heavy commercial vehicle systems.

For workshop technicians performing brake system maintenance or overhauls, this part provides a reliable fit within the brake caliper assembly. Regular inspection of the piston and caliper pin components is essential to prevent system irregularities. When replacing worn parts, ensure the diameter specifications match the original equipment requirements to maintain braking integrity.

Maintenance professionals should verify the diameter and compatibility with the specific engine models (such as D13 or D16 series) to ensure seamless integration into the vehicle's braking architecture.
