A PDU for use in an aircraft includes a wheel (51, 52) configured to convey cargo through a portion of the aircraft. The PDU further includes an armature (108) rotatably coupled to the wheel (51, 52). The PDU further includes a brake pad (112). The PDU further includes a hold solenoid (114) configured to compress the armature (108) against the brake pad (112) by a brake amount in order to apply a hold braking force to the wheel by resisting rotation of the armature (108). The PDU further includes a release solenoid (120) configured to apply a force to separate the armature (108) from the brake pad (112) in order to allow the armature (108) to rotate. The PDU further includes a biasing member configured to compress the armature (108) against the brake pad (112) by a drag amount that is less than the brake amount in order to apply a drag braking force to the wheel (51, 52) by resisting rotation of the armature (108).
