An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.
