A brake mechanism for a utility vehicle which can be installed around a drive shaft or inside a wheel hub. The brake has a non rotatable fixed body (200), a rotatable body (100) rotatable relative to the fixed body (200), at least one brake disc (207) which is non-rotatably relative to the fixed body (200), and at least one rotating brake disc (107) which is fixed for rotation with the rotatable body (100). An actuating member (234) can press the fixed brake disc (207) and the rotating brake disc (107) against each other and against a stop surface (209) on the fixed body to apply the brake. A spring means (230) also exerts an immobilizing force on the actuating member (234) to press the fixed brake disc (207) and the rotating brake disc (107) against each other to apply the brake. A brake release means (231, 233) can exert a brake release force which counteracts the immobilizing force of the spring so that the actuating member (234) no longer presses the fixed brake disc (207) and the rotating brake disc (107) against each other, and a brake applying means (235) can exert a pushing force on the actuating member (234) in the same direction as the immobilizing force to press the fixed brake disc (207) and the rotating brake disc (107) against each other to apply the brake.
