4056012 Gear, Brake Caliper Mechanism — WABCO

The 4056012 Gear, Brake Caliper Mechanism serves as a critical component within the braking system of heavy commercial vehicles. Designed to ensure precise mechanical movement within the air disc brake caliper assembly, this part plays a vital role in maintaining consistent braking force and system-wide reliability. Its robust construction is engineered to withstand the rigorous demands of heavy-duty operation.

This part is engineered to be compatible with WABCO PAN 19 DOUBLE and WABCO PAN 22 DOUBLE systems. 4056012 is the OE-equivalent gear used in WABCO PAN 19 DOUBLE and WABCO PAN 22 DOUBLE brake caliper mechanisms. By adhering to strict dimensional tolerances, it ensures seamless integration into the existing brake architecture, providing a reliable alternative for professional maintenance.

Workshop technicians should ensure that the caliper mechanism is inspected for wear during routine service intervals. When replacing this gear, it is essential to verify that the surrounding brake components are in optimal condition to prevent premature wear. Proper installation within the brake caliper assembly ensures that the mechanical movement remains fluid and free from obstructions under high-pressure braking conditions.
