LEFT REAR BRAKE LINE APPEARS TO BE INSTALLED IN HARMS WAY. THAT IS, AN OBJECT ON THE ROAD COULD BE STRUCK WHICH COULD TEAR AWAY THE BRAKE LINE RESULTING IN LOSS OF BRAKING POWER. OTHER VEHICLES OF THE SAME TYPE ON THE DEALER'S LOT WERE OBSERVED TO BE OF THE SAME DESIGN. IF THIS BRAKE LINE IS LOST DUE TO ROAD HAZARD, WILL BRAKING POWER BE LOST? PLEASE ADVISE. THANKS.
