Claim:
1. An elevator brake, comprising a first braking member, said first braking member being biased by a first spring member into engagement with a braking surface, said first braking member comprising a first armature being arranged such as to be actuated by an electromagnetic actuator, to disengage said first braking member from said braking surface against the biasing force from said first spring member, said first braking member comprising a first housing; and a second braking member, said second braking member being biased by a second spring member into engagement with a braking surface, said second braking member comprising a second armature being arranged such as to be actuated by an electromagnetic actuator, to disengage said second braking member from said braking surface against the biasing force from said second spring member, said second braking member comprising a second housing; wherein said elevator brake comprises a first electromagnetic actuator adapted to actuate said first armature, and a second electromagnetic actuator adapted to actuate said second armature; and wherein said first spring member comprises a plurality of first springs arranged along the periphery of a circle around an axis in equal angular distances to each other, and said second spring member comprises a plurality of second springs arranged along the periphery of a circle around said axis in equal angular distances to each other, said first springs being accommodated within respective recesses formed in said first housing, and said second springs being accommodated within respective recesses formed in said second housing.
