Abstract

Improvements in tandem master cylinders for the motor vehicle brake circuit, of the type comprising a box, the box of which defines a butt bore inside, with a closed end and an open end and slidably receives a simple master piston actuated by an external control element and which defines two pressure chambers in communication in communication, respectively, with two independent brake circuits, the master piston comprising an internal blind bore that slidably receives a floating piston, two opposing surfaces being clamped of the floating piston at the respective pressures in the chambers, moving the floating piston, depending on an imbalance of pressure between the chambers, between two limit positions defined by two stops, characterized in that the floating piston is provided with a projection that extends from the master piston towards the closed end of the bore of the gearbox, the s two limit positions, by which electrical contacts are arranged, connected to an indicator to indicate a pressure imbalance between the two brake circuits.
