WHEN ATTEMPTING TO STOP MY 2007 FORD FUSION THE BRAKES WOULD LOSE FUNCTIONALITY IN VARYING DEGREES. SOMETIMES THE PEDAL WOULD GET SOFT BUT I WOULD BE ABLE TO STOP THE CAR BY PRESSING HARDER AND OTHER-TIMES THE BRAKES WOULD FAIL TO WORK ALL TOGETHER. WHEN THE BRAKES WOULD FAIL THEY WOULD REGAIN FUNCTIONALLY AFTER ABOUT 5-10 MINUTES. WHEN I INSPECTED THE BRAKE SYSTEM THERE WAS NO EVIDENCE OF LEAKING BRAKE FLUID OR BREAK/ROTOR WEAR. WHEN I TOOK THE CAR TO THE SHOP THE MECHANIC ASSURED ME THERE WAS NOTHING WRONG WITH MY ABS BRAKING SYSTEM. THE FAULTY BRAKES IN MY FORD FUSION EVENTUALLY FAILED COMPLETELY WHILE DRIVING AT 65 MPH ON HIGHWAY I-195 WHEN TRAFFIC CAME TO AN ABRUPT STOP. I SUFFERED A LIFE CHANGING CONCUSSION IN THE RESULTING ACCIDENT AS WELL AS LOSING MY CAR AND JOB. I BELIEVE THE PROBLEM IS A FAULTY MASTER CYLINDER AS NO BRAKE FLUID IS LOST FROM THE SYSTEM. PLEASE ADDRESS THIS ISSUE THERE ARE STILL 2007 FORD FUSIONS ON THE ROAD TODAY THAT WILL EVENTUALLY CAUSE MORE SERIOUS ACCIDENTS.
