Abstract
A linkage interconnecting a brake rod with a brake lever in a brake system of a railroad freight car. A length of chain extends from an end of the brake rod, and a monolithic connecting link interconnects an opposite end of the length of chain with a brake lever, so that the brake lever can be moved by pulling the rod, and yet the brake lever is free to move toward the rod if the handbrake system is not in use to keep the brakes applied.
