Brake arrangement, particularly for railway vehicles, where brake pads (7, 8) are in a facing relationship with a brake disc (9), pressed against the disc (9) by means of a pin (6) and at least one spring (5) acting on the pin (6), and where the motion of this pin (6) is derived from linear advance movement of a motion screw (2) with a nut (3) relative to rotary movement of a rotor of an electric motor (1). The nut (3) of the motion screw (2) as well as the pin (6) are in contact with the arm of the first order lever (4), while the area of contact of the nut (3) of the motion screw (2) and the lever (4) is farther from the axis of rotation of the lever (4) than the area of contact of the pin (6) and the lever (4). In order to reduce the coefficient of contact friction between the lever (4) and the nut (3) of the motion screw (2), the lever (4) or the nut (3) can be fitted, in the area of their contact, with a contact element (15) with rounded or spherical surface. In order to reduce the coefficient of contact friction between the lever (4) and the pin (6), the lever (4) can be fitted, in the area of their contact, with a rolling element.
