Abstract of the Disclosure The block brake unit for rail vehicles has a service brake which includes a transmission lever which is pivoted by a brake piston to shift an actuating rod coupled with a brake block carrier. A parking brake includes a spring- loaded cylinder which is coupled by a pivot able parking brake lever through a transmission lever to the actuating rod. An impact wedge coupling comprising a roller and wedge surface is provided between the parking brake lever and the transmission lever. By a suitable choice of the inclination and shape of the wedge surface, the transmission ratio for the parking brake can be readily adjusted for requirements in particular situations without the necessity for changes of the exterior dimensions or mounts and without any changes of the transmission ratio for the service brake. The wedge surface can also be constructed to provide a constant progressive or decreasing transmission ratio and also a fast application for the parking brake.
