Abstract
An actuating device for a brake system of a vehicle a housing and at least one piston slide positioned in the housing for loading the brakes with a pressure medium. The brake system has brakes for the vehicle wheels and a control unit connected to the brakes for sending control signals to the brakes. The brakes are supplied via brake lines with the pressure medium and have wheel sensors connected to the control unit. The wheel sensors determine the rotational velocity of the vehicle wheels during a braking operation and send a signal related to the rotational velocity to the control unit. At least one piezoelectric element is positioned in the housing of the actuating device for actuating the at least one piston slide. The at least one piezoelectric element is connected to the control unit of the brake system.
