Abstract

A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal, or of a force transmitting part which is permanently connected to the brake pedal, to an input member of the brake booster is embodied in such a way that the brake pedal or the force transmitting part can carry out a limited relative movement with respect to the input member. In order to minimize the friction which occurs between the force transmitting part and the input member when the brake booster is activated, the force transmitting part, and/or the input member of the brake booster are/is provided in the region of the relative movement of the two parts with respect to one another with means which reduce friction which occurs during the relative movement of the parts with respect to one another.
