Abstract: A slack adjuster and systems, components, and methods can comprise a base enclosure, a pair of floating piston assemblies, and a pair of sensing piston assemblies. The base enclosure can define an internal chamber that extends along a longitudinal axis of the base enclosure and an inlet channel that extends along a transverse axis of the base enclosure perpendicular to the longitudinal axis. The internal chamber can have a first chamber portion, a second chamber portion, and a center chamber portion that intersects the inlet channel. The floating piston assemblies can be respectively provided in the first and second chamber portions. Likewise, the sensing piston assemblies can be respectively provided in association with the floating piston assemblies.

Abstract: A slack adjuster assembly and systems, components, and methods can comprise a sensing piston assembly that includes a housing, a piston slidably provided in the housing, and a biasing member provided in the housing. The biasing member can be configured to bias the piston away from an end wall of the housing. The piston can have an end wall opposite the end wall of the housing, where the end wall of the piston can have at least one orifice that extends from a first side of the end wall of the piston to a second side of the end wall of the piston.
