NO BRAKING ACTION IS EXPERIENCED FOR OVER 1 SECOND AFTER EMERGENCY HARD BRAKING. TRY BRAKES HARD, WITH FULL BODY WEIGHT, WHEN MOVING 3 MPH IN SIMULATED EMERGENCY AND THEN LETTING OF--THE VEHICLE WILL NOT SHOW DOWN. I HAD A ACCIDENT LAST YEAR IN WHICH A ADDITIONAL 3-5' OF STOPPING DISTANCE WOULD HAVE PREVENTED THE ACCIDENT. I AVOIDED AN ACCIDENT LAST WEEK BY SWERVING AFTER AN ELDERLY LADY ROLLED IN FRONT OF ME WHILE I WAS TRAVELING 25MPH. I AVOIDED IT BY SWERING, THE BRAKES DID NOT START SLOWING THE VEHICLE UNTIL IT WAS TO LATE. I HAVE DEMONSTRATED THIS SAME PROBLEM IN A FRIENDS YUKON ALSO. THE DEALER TOLD ME THAT THIS WAS THE WAY THE VEHICLE WAS DESIGNED AND THAT THERE WAS NOTHING THAT COULD BE DONE TO CORRECT THE PROBLEM.

BRAKES FEEL SPONGY.
