2008 Chevrolet Cobalt service brakes, hydraulic problems

“2008 CHEVROLET COBALT. CONSUMER WRITES IN REGARDS TO CORROSION OF THE HYDRAULIC BRAKE LINES CAUSING FLUID LOSS AND IMPAIRMENT OF FULL SYSTEM BRAKING. *SMD THE CONSUMER STATED AN INVESTIGATION SHOWED THE PROBLEM WAS DUE TO A MANUFACTURING DEFECT. *JB”

“THE REAR BRAKES CLUNKED AND SQUEAKED. TOOK IT TO THE CHEVY DEALERSHIP IN NOVEMBER 2011. THEY REPLACED THE PADS AND TURNED THE ROTORS. SINCE THE CAR WAS TWO MONTHS OUT OF WARRANTY THE CHARGE WAS 307.40. WITHIN 30 DAYS THE BRAKES STARTED MAKING THE NOISE AGAIN BUT NOT AS OFTEN OR AS LOUD. THE SOUND HAS GOTTEN PROGRESSIVELY WORSE AND MORE OFTEN. INSTEAD OF A SQUEAK THERE IS NOW AN EXTREMELY LOUD GRINDING NOISE WHEN STOPPING, PARTICULARLY WHEN THERE IS MOISTURE PRESENT. THE BRAKE PADS STILL HAVE PLENTY OF MATERIAL ON THEM AND THE ROTORS ARE SMOOTH. THE NOISE IS DEAFENING IN PARKING GARAGES AND CAN EASILY BE HEARD 1/8TH OF A MILE AWAY. STOPPING DISTANCE HAS INCREASED AND THE VEHICLE DOES NOT FEEL SAFE. *KB”

“I HAVE HAD TO REPLACE THE REAR BRAKES 4 TIMES AND STILL HAVEN'T REPLACED THE FRONT I GET STOCK PADS AND ROTORS FROM CHEVY DEALER! AND WITHIN 500 MILES THE ROTORS ARE ALL SCORED UP AND LOOK LIKE THEY HAVE 20K ON THEM. I SEE THIS BEING A SERIOUS SAFETY HAZARD FOR SOMEONE WHO DOES NOT REALIZE IT BECAUSE THEY JUST REPLACED THEM! FIX THIS ISSUE PLEASE! I NOTICED THIS FOR THE 4TH TIME ON DECEMBER 1ST. I WAS BACKING UP AND IT MADE A HORRIBLE SOUND I GOT OUT TO CHECK AND THE REAR PADS ARE ALMOST GONE! I HAVE PUT MAYBE 8K ON THEM AND THE ROTORS LOOK LIKE A TIGER ATTACKED THEM, I DON'T BELIEVE I SHOULD HAVE TO PAY FOR THIS AGAIN SO SOON! *TR”

“REAR BRAKE ROTORS ARE IRREPARABLY SCORED AND WARPED AFTER 11,000 MILES, PREVENTING THE REAR BRAKES FROM WORKING CORRECTLY AND DECREASING BRAKING EFFECTIVENESS. THIS IS COMMON ON 2008 COBALT SSES. *TR”

“TL* THE CONTACT OWNS A 2008 CHEVROLET COBALT SS. THE CONTACT WAS DRIVING 10 MPH WHEN THE VEHICLE FAILED TO DECREASE IN SPEED AS THE BRAKES WERE DEPRESSED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS REPAIRED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 35,000 AND THE CURRENT MILEAGE WAS 35,300.”

“BOUGHT MY COBALT SS NEW FROM DEALER, WITH LESS THEN 5,000 MILES REAR BRAKES WERE SQUEALING AND VERY OBNOXIOUS. UPON INSPECTING AND BRINGING THE CAR TO THE DEALERSHIP WAS TOLD THAT MY BRAKES HAD GOUGES IN THEM AND NEEDED TO BE REFINISHED AND CLEANED AS WELL AS NEW PADS INSTALLED. THIS WAS NOT COVERED UNDER THE WARRANTY AS THEY SAID IT WAS WEAR AND TEAR AND THE NOISE WAS NORMAL. *TR”
