4156018 Piston, Brake Caliper Pin

The 4156018 piston is a critical component within the air disc brake caliper system, designed to provide reliable actuation and structural integrity under heavy-duty conditions. This part ensures that the braking force is applied accurately within the caliper assembly, maintaining consistent performance for heavy commercial vehicles.

4156018 is the OE-equivalent piston used in the MERITOR ELSA 2, ELSA 195, ELSA 225, and EX 225 systems. It is specifically engineered to maintain the operational standards of these heavy-duty braking hardware configurations. By ensuring exact fitment, this part supports the stability of the braking mechanism during intense thermal and mechanical stress.

Workshop technicians should ensure that the caliper housing is clean and free of debris before installation to maintain optimal movement. Given its role in the brake caliper pin assembly, regular inspection of the piston and its surrounding seals is recommended during routine maintenance intervals to prevent system failure. This component is designed for professional assembly in professional workshop environments to ensure vehicle safety and compliance.
