Service brakes

“WHILE DRIVING ON THE FREEWAY, I HIT THE BRAKES AND THEY STOPPED WORKING. ON THE DASHBOARD IT SAID THAT BRAKES NEEDED TO BE SERVICED. LUCKILY I WAS ABLE TO STOP BY PUTTING MOST OF MY WEIGHT ON THE BRAKE PEDAL. I PULLED TO THE SIDE AND INSPECTED THE CAR, NOTHING WAS WRONG. I PROCEEDED TO RESTART THE CAR AND THE BRAKES APPEARED TO BE WORKING FINE. I TOOK THE CAR TO THE FORD DEALERSHIP AND THEY VERIFIED THAT AN ISSUE HAD OCCURRED, HOWEVER THEY DID NOT KNOW HOW TO FIX THE ISSUE AND CONTACTED FORD. AFTER 4 DAYS THEY CLAIM THAT A TUBE WAS DEFECTIVE AND THAT THE BRAKES ARE FIXED. NO CAR SHOULD HAVE A FAILURE THAT CAUSES SOMEONE THE INABILITY TO STOP, THIS IS POOR ENGINEERING. ALL CARS SHOULD HAVE A FAIL SAFE THAT ALLOWS TO THE CAR TO STOP IN EVENT OF CATASTROPHIC FAILURE. WHAT MAKES THE INCIDENT ODD IS THAT RESTARTING THE CAR FIXED THE PROBLEM FOR ME, ALLOWING ME TO DRIVE IT TO A DEALERSHIP.”
