4506010 Piston, Brake Caliper Pin — VOLVO

The technical function of this piston within the brake caliper pin assembly is to ensure precise movement and pressure application within the braking system. Engineered for heavy-duty grade materials, this component provides essential stability and durability under rigorous braking cycles in heavy commercial vehicles.

4506010 is the OE-equivalent of the MERITOR 68320070 and VOLVO 1697452 pistons used in the braking systems of MERITOR and VOLVO vehicles. This component is engineered to meet strict technical requirements for seamless integration into the air disc brake caliper assembly.

Workshop technicians should ensure that the piston is inspected for surface integrity during every service interval. Given its diameter of Ø 58 / 63 mm, precise fitment is critical for maintaining optimal braking performance. Regular checks of the caliper housing and pin lubrication are recommended to prevent system wear.

Proper installation of this piston helps maintain the integrity of the pneumatic braking system. It is designed to withstand high-pressure environments, ensuring that the heavy commercial vehicle remains responsive and safe during operation.
