An adjustable force safety brake for use in an elevator system. The adjustable force safety brake includes a safety block, first and second braking elements housed in the safety block and an electromagnet. The safety block includes a channel arranged to receive a guide rail of an elevator system in use. The first braking element is configured to move from an initial position into a position of engagement with the guide rail received in the channel to create a braking force, and the second braking element is configured to create an additional braking force on the guide rail when the first braking element is in the position of engagement. The electromagnet is operable to selectively produce a magnetic force which acts on the second braking element in a sideways direction away from the channel so as to reduce the additional braking force on the guide rail.
