POWER BRAKE BOOSTER FAILED. *YH

WHEN APPLYING BRAKES THE PEDAL WENT TO THE FLOOR, AND THE VEHICLE DID NOT STOP. DEALER COULD NOT DUPLICATE PROBLEM. *AK

I HAVE TRIED CALLING A DEALER - THEY KNOW NO MORE THAN I DO. HELP!!

WHEN DRIVING VEHICLE AT VARIOUS SPEEDS, ABS BRAKES WOULD FAIL TO STOP VEHICLE. WOULD FADE OUT, AND STOPPING DISTANCE HAS BEEN INCREASED. VEHICLE ALSO HESITATED IN REVERSE. WHEN IN DRIVE POSITION WOULD RAMBLE & LOSE POWER. ALSO, THERE ARE DEFECTIVE VALVES IN ENGINE. ALSO DEFECTIVE DRIVESHAFT RUBBER BEARINGS CAUSE VEHICLE TO VIBRATE. HAVE TAKEN VEHICLE TO MIDAS & NOT DEALERSHIP. THE PROBLEM COULD NOT BE SOLVED. *AK

WHEN BRAKING ON WET PAVEMENT, BRAKE PEDAL GOES TO PEDAL STOP AND VEHICLE IS NOT STOPPING. THE DEALER HAS PUT ON BRAKE BOOSTER, ABS DUMP VALVE MASTER CYLINDER BLED AND ADJUSTED BRAKES. GMC WAS INVOLVED WITH DIAGNOSIS. THIS WAS DONE ONE YEAR AGO TRUCK STILL DOES THIS. I REALIZE RECALL UNDER WAY INVOLVING 4WD VEHICLES BUT NOT TWO WHEEL DRIVE. FROM WHAT I HAVE READ SOUNDS LIKE THE SAME PROBLEM. HOW SHOULD I GO ABOUT GETTING THIS RESOLVED? SO FAR ABOUT $1800.00 HAS BEEN PUT INTO THIS PROBLEM. I DO NOT KNOW WHERE TO GO GET A RESOLUTION TO THIS.

WHILE DRIVING AT 55 MPH AND APPLYING THE BRAKES, THE BRAKES WENT STRAIGHT TO FLOORBOARD, AND THE ABS DIDN'T WORK . ALSO, ENGINE CHECK LIGHT KEPT COMING ON. *AK
