Abstract
A brake system for a piece of equipment includes a series of rotors and stators, and a first brake actuator including at least one first piston positioned within a first chamber such that pressurization of the first chamber causes the at least one first piston to operatively engage at least one of rotors or stators such that the rotors and stators are compressed together and thereby create braking torque, and may also include a second brake actuator including at least one spring operatively coupled to at least one second piston positioned within a second chamber such that depressurization of the second chamber causes the at least one second piston to operatively engage at least one of the rotors or stators such that the pluralities of rotors and stators are compressed together and thereby create braking torque.
