NHTSA Complaint #10326392 — 1997 GMC SIERRA 1500

THE TROUBLE I AM HAVING IS WITH THE BRAKING SYSTEM . IT HAS BEEN PROFESSIONALLY MAINTAINED BUT THE PROBLEM STILL PERSISTS. THE BRAKES LOCKOUT AT SLOW SPEEDS AND I HAVE TO USE 2 FEET TO PRESS DOWN THE PEDAL AND STOP THE TRUCK . IF I WERE DRIVING AND STOPPED AT A LIGHT THERE WOULD BE NO PROBLEM .HOWEVER IF I WERE THEN TO RELEASE THE PEDAL AND APPLY IT AGAIN THE ABS SEEMS TO ACTIVATE AND I BASICALLY CANNOT STOP THE VEHICLE. I DID HIT SOMEONE ONCE BUT IT DIDN'T DO MUCH DAMAGE BECAUSE I WAS GOING SLOW UNDER 5MPH. THIS HAS BEEN HAPPENING SINCE I BOUGHT THE TRUCK 5 YEARS AGO BUT I FIGURED IT WAS HOW THE TRUCK WAS SUPPOSED TO BE. THIS PROBLEM HAPPENS UNDER 15 MPH. YOU CAN HEAR THE ABS MOTOR ACTIVATE BUT THE FEELING YOU GET FROM THE RESPONSE OF THE PEDAL IS HARD LIKE THE VACUUM BOOSTER IS BAD BUT ONLY TEMPORARY. IF YOU GET THIS PROBLEM IT SEEMS THAT IF I RELEASE THE PEDAL AND TAP IT THE BRAKES WILL RETURN BUT ONE DAY IT WILL BE TOO LATE AND THERE MAY BE SOMEONE LYING UNDER MY TRUCK. I MUST ALSO SAY THAT I AM A MECHANIC AND POLICE OFFICER SO I DO KNOW SOMETHING ABOUT VEHICLE HANDLING RESPONSE AND REPAIR. *TR
