<p>The roller has a step roller and a brake body that is moved by a brake pedal (4) over a coupling drive (5) in a direction to a circumferential surface and held at the surface in its braking position (12) till the pedal is backward-displaced from the brake position to a releasing position. An end stop (13) is provided for the pedal on its path from the releasing position to the brake position, where the pedal runs on the end stop under predetermined pedal force.</p> |
