4156053 Piston, Brake Caliper Shaft

This precision-engineered piston is a vital component within the brake caliper shaft system, designed to maintain optimal pneumatic control and structural integrity during heavy-duty operation. As a critical part of the air disc brake caliper assembly, it ensures consistent pressure application and reliable braking performance for heavy commercial vehicles.

4156053 is the OE-equivalent piston used in the MERITOR DX 225 braking system. This component is manufactured to meet strict dimensional tolerances to ensure seamless integration with compatible heavy-duty vehicle systems. It is specifically designed for the right-hand (R) direction side of the brake assembly.

Workshop technicians should ensure that the caliper housing and surrounding seals are inspected during replacement to maintain system efficiency. Regular maintenance of the brake caliper shaft components is essential to prevent uneven wear and ensure the longevity of the braking performance in demanding environments. This part is engineered for high-strength service in heavy commercial vehicle applications.

Proper installation requires adherence to standard heavy-duty braking service protocols to ensure the piston moves freely within its housing. Given its role in the air disc brake system, ensuring no debris or contamination exists in the assembly line is critical for long-term durability and safety.
