The present invention relates to an emergency brake assembly for locking a wheel hub of a stationary vehicle in a substantially motionless state, the wheel hub of the type having an associated disc rotor, the emergency brake assembly including a first emergency brake mechanically or electrically configured to apply a radial pressing force on an inner surface of a drum that rotates correspondingly with the wheel hub for the purpose of substantially preventing rotation of the drum relative to the first emergency brake and hence substantially preventing rotation of the wheel hub, or apply an axial clamping force on an external surface of the disc rotor associated with the wheel hub for the purpose of substantially preventing rotation of the disc rotor relative to the first emergency brake and hence substantially preventing rotation of the wheel hub, and a second emergency brake that is electrically configured to apply an axial clamping force on an external surface of the disc rotor associated with the wheel hub for the purpose of substantially preventing rotation of the disc rotor relative to the second emergency brake and hence contributing further to substantially preventing rotation of the wheel hub, wherein the combination of forces applied by the first and second emergency brakes ensures that a sufficient force is applied to lock the wheel hub and thereby maintain the wheel hub in said substantially motionless state.
