The brake regulator for a motor vehicle, comprises a body (1) pierced with a bore in which an annular gasket (7) defines first and second chambers (2, 3), of which the first (2) is connected to the circuit of a master cylinder and the second (3) to at least one brake motor, and a valve-forming piston (8) movable in axial translational motion in an annular spacer (18) bearing against the annular gasket (7). The piston (8) has a diameter larger than that of the central orifice of the annular gasket (7) forming a valve seat, and is equipped with a pusher (9) which passes through the annular gasket (7) and the first chamber (2) and projects sealingly from the body (1). The assembly consisting of the annular gasket (7) and of the annular spacer (18) is mounted to be movable in axial translational motion, and the second chamber (3) also comprises an elastic mechanism (6) confined between the annular spacer (18) and the bottom of the bore.
