A parking brake system. The parking brake system may include a braking assembly frame having a front end portion and a second end portion; a pressure bar disposed at the second end portion of the braking assembly frame, wherein the pressure bar may be configured to apply a braking force to a tire in a first state and to remove the braking force in a second state; and a braking control actuator operatively linked to the braking assembly frame, wherein the braking control actuator may be configured to cause the braking assembly frame to move the pressure bar between the first state and the second state.
