The invention relates to a caliper brake for a brake disc, in particular for elevator drives. Said brake comprises a brake body that is mounted on a fixed bolt ( 7 ) in a floating manner ( 1 ) and a brake caliper ( 2 ) that impinges on the brake disc ( 3 ) from the outer periphery of the latter, in addition to a solenoid ( 14 ) that is integrated into the brake body ( 1 ) to electromagnetically pull a spring-loaded armature disc ( 4 ) against the brake body ( 1 ). Said armature disc ( 4 ) and the section of the brake caliper ( 2 ) lying axially opposite are equipped with friction linings ( 5, 6 ) for engaging with the two end faces of the brake disc ( 3 ). To release or centre the caliper brake in relation to the brake disc at any time, a dual-arm rocker lever or bracket ( 8 ) is pivotally mounted on the fixed bolt, one limb ( 15 B) of said lever or bracket being connected to the peripheral surface of the armature disc ( 4 ) and the other limb ( 15 A) to the brake caliper, in such a way that the rocker lever or bracket ( 8 ) displaces the armature disc ( 4 ) when the brake is disengaged, simultaneously redirecting said movement into a displacement of the brake caliper ( 2 ) in the opposite direction, in order to obtain an air gap (s/ 2 ) on both sides of the brake disc ( 3 ).
