Abstract: A valve including a valve housing, a casing, a spring guide, and a retaining cup. The casing may be disposed within the valve housing and may include a bore. The spring guide may be disposed within the bore and the retaining cup may be disposed partially around the casing to engage and retain the spring guide at least partially within the bore of the casing.

Abstract: Systems and methods for emergency brake systems are provided herein. In this regard, a brake system may comprise a summing lever having a first end and a second end, a brake handle coupled to the first end of the summing lever, the brake handle rotatably coupled about a first axis, and a linear actuator having a plunger, the plunger being coupled to the second end of the summing lever. In various embodiments, an idler link may be coupled between the brake handle and the first end of the summing lever. The brake system may further comprise a brake cable coupled between the summing lever and a brake metering valve. The brake metering valve may be actuated in response to at least one of the brake handle being rotated about the first axis or the linear actuator being actuated.
