Abstract

A service brake system for a locomotive includes a brake cylinder, a first lever defining a first end and a second end, a first engagement element coupled with the first lever at the second end, a second lever extends in an orthogonal direction relative to the first lever, a bracket assembly, and a second engagement element. The first lever is adapted to pivot relative to a pivot point. The second lever is adapted to be coupled with a brake shoe of the service brake system and define a third end and a fourth end. The bracket assembly is adapted to engage the first lever with the second lever and includes first and second brackets. The second engagement element is coupled with the second bracket and at least partially received within the second bracket and extends parallel to the first engagement element.
