An emergency braking method for an aircraft, comprising using a progressing parking brake controlled by a lever (10) that can be actuated by the pilot between a "0%" position in which the brakes are connected to the return pressure of the aircraft, and a "100%" position in which the brakes are connected to the feed pressure of the aircraft, the lever being blockable in the 100% position in order to provide parking braking when the aircraft is stationary. According to the invention, the emergency braking method is characterized in that it comprises: using a valve having an outlet port connectedto the brakes, a return port, and a feed port, the valve presenting a state connecting the outlet port to the return port and a state connecting the outlet port to the feed port; and controlling thevalve to occupy one or other of those states by pulse width modulation (PWM) having a duty ratio (R) that is a function of the position of the lever in order to deliver the brakes with pressure lyingin the range return pressure to feed pressure, depending on the position of the lever.
