1997 GMC Z-71 — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

A VEHICLE WAS STOPPED ON THE ROADWAY WAITING FOR A VEHICLE IN FRONT OF HIM TO MAKE A LEFT TURN, I SAW THE TWO STOPPED VEHICLES AND WHEN TRYING TO APPLY THE BRAKES ON MY 1997 GMC TRUCK FROM ABOUT 200+ FEET AWAY, THE BRAKE PEDAL JUST BECAME ROCK HARD AND TRUCK DIDN'T SLOW DOWN OR BRAKE CAUSING ME TO HIT THE STOPPED VEHICLE. NO TYPICAL ANTI LOCK PULSATIONS WERE PRESENT OR FELT JUST A ROCK HARD PEDAL THAT COULDN'T BE PUSHED DOWN FURTHER NO MATTER HOW HARD I TRIED. THERE ARE ABSOLUTELY NO SKIP OR SKID TYPE MARKS ANYWHERE. I HAVE SINCE BEEN CITED WITH FOLLOWING TO CLOSE BY AN OFFICER NOT PRESENT DURING THE ACCIDENT, SINCE I COULDN'T STOP. I WISH TO REPORT THIS AND ALSO KNOW IF OTHER COMPLAINTS EXIST OF THIS NATURE FOR SIMILAR VEHICLES. I HAD OTHER PULSATIONS AND SIMILAR HARD PEDAL AND THIS WAS SUPOSEDLY REPAIRED BY REPLACING SPEED SENSOR AND MASTERCYLINDER AY APPROX 56000. AFTER STILL FEELING UNUSUAL BRAKE PEDAL PULSATIONS I WAS TOLD IT IS A CONDITION THAT MAY INTERMITENTLY EXIST AND IS NORMAL. 1997 GMC TRUCK VIN # [XXX]. *AK UPDATED 07/26/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
