The disc is mounted to the adapter sleeve of the wheel, and the housing is mounted to an annular ring mounted to an axle of the vehicle. A pressure plate is provided within the housing and located between the annular intermediate wall and the housing wall opposite from the disc and is parallel thereto. The brake lining ring including a backing plate is provided adjacent a radial friction surface of the disc, and push rods extend between the pressure plate and the backing plate of the brake lining ring.
