4156020 Piston, Brake Caliper Shaft

The 415_6020 piston is a critical component within the air disc brake system, specifically designed for the brake caliper shaft assembly. This part plays a vital role in maintaining precise braking force and ensuring the stability of the caliper mechanism during heavy-duty operation. Manufactured with high-strength components, it provides the necessary durability to withstand extreme thermal and mechanical stresses common in heavy commercial vehicle braking-suspension systems.

This product is engineered to be compatible with MERITOR DX 175 systems. 4156020 is the OE-equivalent piston used in MERITOR DX 175 heavy commercial vehicles. By maintaining strict dimensional tolerances, this part ensures seamless integration and optimal performance within the braking architecture.

For workshop technicians, this component is designated for the 'L' (Left) direction. When performing brake system maintenance or caliper overhauls, it is essential to verify the directionality and ensure that all assembly surfaces are clean and free of debris. Regular inspection of the piston and shaft interface is recommended to prevent any degradation in braking responsiveness or system pressure.
