ABSTRACT:
An operating lever system for the brake system of a vehicle has a rod to actuate the brake system and the rod is connected to a pivotally mounted intermediate lever. A pivotally mounted actuating lever has a roller thereon engagable with the intermediate lever. A further roller is resiliently urged against a cam surface on the intermediate lever which guides this roller substantially concentrically of the pivot mount of the intermediate lever during actuation of the rod in the braking direction and at a decreasing distance from the pivot mount upon further moving of the rod in the braking direction.
