Abstract

A pneumatic wheel brake for a vehicle includes a brake lever operable by a compressed air cylinder, and a brake application device operable by the lever. Employing the brake application device, a first brake element can be pressed against a second when the lever is operated. The wheel brake also includes an actuating device, which can be motor driven, which force can be applied to parts of the brake application device, at least when the lever is not operated, to press the first brake element against the second. The wheel brake also has a spring accumulator element arranged outside the compressed air cylinder. Force can be applied to the spring accumulator element by the actuating device; and force can be applied to parts of the brake application device by the spring accumulator element, at least when the lever is not operated. Thereby, the first brake element can be pressed against the second.
