1. An elevator system arrangement including a car, a brake strip and an elevator brake device for braking the car on the brake strip, the elevator brake device comprising:
a brake housing horizontally displaceably mounted in the elevator brake device and in a standby position by an applied force;
a brake pad that is supported on the brake housing by at least one spring;
a brake body movably arranged on the brake housing and is displaceable or rotatable upon contact with the brake strip to clamp the brake strip between the brake body and the brake pad;
a pusher arranged on the brake housing such that the brake strip can be arranged between the brake body and the pusher;
wherein, in the standby position of the brake housing, a distance between the brake body and the pusher corresponds at least to a thickness of the brake strip plus a first clearance between the brake body and the brake strip and a second clearance between the pusher and the brake strip;
wherein the pusher is adapted to be advanced in a direction of the brake body along a line of action extending perpendicularly to the brake strip to press the pusher against the brake strip when the brake strip is arranged between the brake body and the pusher;
wherein the line of action and a direction of travel of the car lie in a reference plane;
a car-remote plane is oriented in parallel with the reference plane such the elevator brake device is entirely located on a car side of the car-remote plane and the car-remote plane touches the elevator brake device, and a car-side plane is oriented in parallel with the reference plane and such that the elevator brake device is entirely located on a car-remote side of the car-side plane and the car-side plane touches the elevator brake device;
when the elevator brake device is installed on the car, a distance from the car-side plane to the brake strip less than 70% of a distance from the car-side plane to the car-remote plane;
a pressure lever pivotally mounted on the brake housing and acting on the pusher during a braking process to press the pusher against the brake strip thereby laterally displacing the brake housing and bringing the brake body into contact with the brake strip; and
wherein the pressure lever includes a pivot pin aligned horizontally relative to a vertical direction of travel of the car.
