An elevator system caliper brake includes first and second brake levers each with a brake pad wherein the brake levers move the brake pads relative to one another along an actuation axis. The first brake lever is rotatably mounted at a stationary first mounting point at a housing of the brake, and the second brake lever is rotatably mounted at a second mounting point on an intermediate lever that is rotatably mounted at the brake housing. A tension element can be moved approximately parallel to an actuation axis and is connected to the brake levers at mounting points between the respective brake pads and the brake lever mounting points. A closing spring moves the first and second brake levers to decrease the distance between the brake pads and a linear spindle drive connected to the intermediate lever selectively counteracts the closing spring to increase the distance between the brake pads.
