4502019 Piston, Brake Caliper Pin

The heavy-duty piston is a critical component within the air disc brake caliper system, ensuring precise movement and reliable braking force. This part is engineered to withstand high-pressure environments and maintains structural integrity under demanding heavy commercial vehicle service conditions. Its role is essential for maintaining stable braking performance and ensuring the safety of the vehicle during operation.

4502019 is the OE-equivalent piston used in DAF, IVECO, MAN, MERITOR, RENAULT TRUCKS, and VOLVO heavy commercial vehicle braking systems. This component is manufactured to meet strict technical requirements for diameter and tolerance to ensure seamless integration within the brake caliper assembly. It provides a high-strength solution for professional workshop technicians and fleet managers seeking reliable replacement parts.

For workshop technicians, this piston is designed for easy assembly within the caliper pin group. It is vital to ensure that the surrounding brake components and hydraulic/pneumatic lines are inspected during installation to maintain optimal system pressure and prevent leaks. Regular maintenance of the braking system helps preserve the lifespan of this piston and ensures consistent braking response across all operating temperatures.

Maintaining the correct diameter of Ø 68 mm is crucial for proper fitment in compatible air disc brake systems. Using high-grade components helps prevent common issues such as uneven brake wear or reduced braking efficiency in heavy-duty applications.
