Abstract

A railcar brake system includes a first brake beam and a second brake beam configured to be mounted on opposite sides of a bolster of a railcar truck; a brake cylinder connected to the first brake beam; a first lever and a second lever pivotally connected to the first brake beam at separate points, the first lever and the second lever also being connected to opposing ends of the brake cylinder to connect the brake cylinder to the first brake beam; a slack adjuster connected to the second brake beam; a first push rod connecting the first lever to the second brake beam and the slack adjuster; and a second push rod connecting the second lever to the second brake beam and the slack adjuster. Actuation of the brake cylinder causes movement of the brake beams via the first and second levers and the first and second push rods.
