2008 Chevrolet Colorado SERVICE BRAKES, HYDRAULIC

TL* THE CONTACT OWNS A 2008 CHEVROLET COLORADO. WHILE DRIVING 35 MPH, THE BRAKE PEDAL REQUIRED EXCESSIVE FORCE IN ORDER TO STOP THE VEHICLE. THE FAILURE OCCURRED ON NUMEROUS OCCASIONS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE REAR BRAKE DRUMS FAILED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

MY VEHICLE ALMOST COMPLETELY LOST ALL OF IT'S BRAKES. UPON SHORT INSPECTION UNDER THE HOOD, I FOUND THE GROMMET THAT SEALS THE BRAKE SYSTEM CHECK VALVE TO THE POWER BOOSTER ALMOST COMPLETELY RIPPED INTO TWO PIECES. PRIOR TO THIS INCIDENT, NO MAINTENANCE OR ANY OTHER UNDER HOOD MAINTENANCE HAD BEEN PERFORMED ON THIS VEHICLE OTHER THAN REGULAR OIL CHANGES. THIS PART IS NOWHERE NEAR THE AREA REQUIRED ACCESS FOR AN OIL CHANGE SO THERE IS NO WAY THIS WAS CAUSED BY IMPROPER HANDLING OF THE PART.

THE REAR BRAKE ADJUSTERS ARE FAULTY ON THE 2008 CHEVY COLORADOS. GM HAS ISSUED A TSB FOR THIS ISSUE #07-05-24-001B. THE SYMPTOMS ARE SQUEALING REAR BRAKES, HIGH REAR BRAKE WEAR, RUSTING ON DRUMS AND MORE. THE TSB IS ONLY GOOD UNTIL 36,000 MILES. MANY DEALERSHIPS WILL NOT PERFORM THE TSB REPAIR WHICH IS FREE. THEY WILL INSTEAD CHARGE THE CUSTOMER FOR A REAR BRAKE CLEAN AND ADJUST WHICH ONLY TEMPORARILY ELIMINATES THE SQUEAL UNTIL THE ADJUSTS FAIL TO ADJUST THE SHOES PROPERLY AGAIN. THIS ISSUE CAN CAUSE LOSS OF CONTROL UNDER BRAKING, ESPECIALLY ON WET ROADS. THIS IS AN ONGOING ISSUE WITH APPROXIMATELY 40 INSTANCES SEEN IN MY FLEET OF 92 COLORADOS-SO FAR . ISSUE OCCURS AT ANY MILEAGE. DOCUMENTED RANGES ARE FROM 10,000 TO END OF WARRANTY. VEHICLES HAVE SEVERAL OTHER ISSUES AS WELL. *TR

REAR BRAKE ISSUES NO PROBLEMS FOUND AT DEALER 2 TIMES I HAD TAKEN IT TO THEM. REAR BRAKE NOISE SCREECHING SQUEALING, LOCK UP WHEN MOISTURE IS PRESENT, AND IN AN EMERGENCY STOP THE PEDAL GETS REAL STIFF AND IS HARD TO STOP. I PUT IN A COMPLAINT TO CHEVROLET AND THEY SAID THERE IS NOTHING THEY CAN DO. I FEEL UNSAFE DRIVING THIS VEHICLE AFTER TWO CLOSE CALLS WITH EMERGENCY STOPPING. PLEASE HELP ME I DON'T KNOW WHAT TO DO I DON'T WANT TO GET INTO AN ACCIDENT. *TR
