Abstract

The present invention relates to a self-amplifying electromechanical partial lining disc brake, having a ramp mechanism as a self-amplification device. According to the invention, a rack for driving a friction brake pad is situated between roller elements of the ramp mechanism, particularly at a geometrical centroid of an imaginary surface defined by the roller elements. As a result a load is distributed to the roller elements in a more uniform fashion and the pressing force of the friction brake pad against a brake disc when the partial lining disc brake is actuated is distributed more uniformly and counteracts irregular pad wear.
