This could maybe be the problem but i have a left hand drive plus four and since i have the car i have the same complain about the travel and the softness of the brake pedal. The exhaust is rightside but the master cylindre is leftside. One month after the reception of my car i bypassed my dealer and send a mail to the factory . The answer was to contact my dealer first and the plus four was very safe and the braking sufficient for the car.
