4020012 Ring, Brake Caliper Mechanism — WABCO

The 4020012 Ring, Brake Caliper Mechanism serves a critical role in the structural integrity and function of the braking system. As a specialized component within the air disc brake mechanism, it is designed to withstand high-stress environments and maintain its shape under heavy-duty operating conditions. This ensures that the caliper mechanism operates with consistent precision during vehicle braking cycles.

This part is the OE-equivalent component used in WABCO MAXX 22 L, MAXX 17, MAXX 19, MAXX 22, and MAXX 22 T systems. By maintaining exact dimensional standards, the 4020012 ensures seamless integration with existing brake architectures. It is designed specifically for heavy commercial vehicles to support reliable braking performance in demanding transport environments.

For workshop technicians, selecting this high-strength component ensures that the brake caliper mechanism maintains its intended movement and seating. Regular inspection of the caliper mechanism components is recommended during routine maintenance to prevent system degradation. This part is engineered to facilitate smooth assembly and long-term durability within the pneumatic braking architecture.
