ABSTRACT:
A vehicle braking system with an electronically controllable brake servo unit which comprises a first pneumatic working chamber (13) and a second pneumatic working chamber (14) which are separated from each other by a movable wall (11), wherein a travel sensor (20) is provided for the detection of displacements of the movable wall (11) relative to a stationary wall (5b) of at least one of the two working chambers (13, 14) is improved to simplify assembly and adjustment of the travel sensor in such a manner that a wall (11) is provided with an opening (19) through which a measuring element (10) being connected with another wall (5b) is projecting, and that the travel sensor (20) converts a relative movement between the measuring element (10) and the travel sensor (20) in the direction of the movement of the movable wall (11) into a signal used for controlling the brake servo unit.
