4502020 Piston, Brake Caliper Pin

The piston is a critical component within the braking system, ensuring precise pressure application and reliable deceleration. Designed with a diameter of Ø 34 x 75 mm, this part provides the necessary structural integrity for heavy-duty braking operations. It is engineered to maintain performance under demanding thermal and mechanical stresses common in heavy commercial vehicle applications.

4502020 is the OE-equivalent piston used in WABCO systems for vehicles such as DAEWOO, DAF, IVECO, ASHOK LEYLAND, PACCAR, and LEYLAND. This component ensures the air disc brake caliper operates with maximum efficiency. It is specifically engineered to meet the rigorous standards required for heavy-duty transport and long-haul stability.

For workshop technicians, this piston offers a straightforward assembly process within the brake caliper pin group. Regular inspection of the braking system and ensuring the piston moves freely within its housing is essential for maintaining optimal braking response. Proper maintenance of the caliper assembly helps prevent system degradation and ensures consistent safety during heavy-duty service intervals.
