WHILE PULLING OUT OF PARKING SPACES (USUALLY), THE BRAKE WILL NOT GO DOWN. I HAVE TO PUSH THE PEDAL WITH ALL MY STRENGTH TO GET THE CAR TO STOP.

THEY REPLACED THE LINE, BUT THE PROBLEM STILL OCCURS AT LEAST ONCE A WEEK.

I WAS TRAVELING APPROXIMATELY 35 TO 40 MPH ON A STRAIGHT ROAD. THE VEHICLE IN FRONT OF ME STOPPED ABOUT 75 FEET AHEAD OF ME. I PRESSED ON THE BRAKE PEDAL TO STOP BUT THERE WAS NO PRESSURE AND IT WENT TO THE FLOOR. DUE TO HAVING NO BRAKES, I HIT THE BACK OF THE OTHER CAR.

CAR TYPE: CHEVROLET AVEO 2005 MODEL: LS SEDAN WITH 14" WHEELS SINCE I PURCHASED THIS CAR IT HAS EXHIBITED VIBRATION IN THE FRONT END AND STEERING WHEEL WHILE DRIVING (ABOVE 50 MPH) AS WELL AS VIBRATION WHILE BRAKING. CAR WAS TAKEN INTO CHEVY TO BE REPAIRED. CAR STILL VIBRATES. UPON FURTHER RESEARCH I DISCOVERED THAT MANY OTHERS HAVE THIS EXACT PROBLEM. CHEVY HAS BEEN UNABLE TO FIX THIS PROBLEM. SIGNIFICANT VIBRATION WHILE DRIVING AND BRAKING (ESPECIALLY) IS A SAFETY HAZARD. SINCE CHEVY IS EITHER UNWILLING OR UNABLE TO FIX THIS SERIOUS PROBLEM I'M HOPING THE NHTSA WILL INVESTIGATE THIS PROBLEM. *JB
