Abstract

The present invention discloses an electromechanically operable disc brake for automotive vehicles which comprises a floating caliper as well as an actuating unit arranged on the caliper. The actuating unit includes an electric motor which, by the intermediary of a reduction gear, readjusts an actuating element which is used to move one of two friction linings that are slidable in the brake caliper into engagement with a brake disc. To permit an individual adjustment of the desired brake force, especially for use of the disc brake in an automotive vehicle, according to the present invention, a force-measuring device (23) is interposed in the flux of force between the caliper (1) and the actuating unit (2), and the output signals of device (23) are adapted to be sent to a control circuit (26) that influences the current supplied to the electric motor (6), and/or the voltage.
