2000 GMC Sonoma brake problems

SERVICE BRAKES

I HAD A NEAR DEATH ACCIDENTS (TWICE) DUE TO CATASTROPHIC BRAKE LINE FAILURE FROM SEVERELY RUSTED BRAKE LINES THE FRONT LEFT AND THE INTERMEDIATE LINE FROM FRONT TO REAR SECTION ON TOP OF FRAME RAIL. FIRST INCIDENT WAS AT SPEED OF 45 MPH ON HIGHWAY WITH HARD STOP REQUIRED TO AVOID STOPPED TRAFFIC AHEAD. SECOND FAILURE WAS MORE INSIDIOUS WITH PROGRESSIVE BRAKE LINE RUST THROUGH/ LEAK SPOT TO REAR BRAKE LINES WITH FIN THROUGH AND FAILURE. THIS IS NOT COMPLICATED ... SIMPLY SUBSTANDARD MATERIALS FOR ONE OF THE MOST CRITICAL COMPONENTS IN A VEHICLE. IT SHOULD NOT MATTER WHAT CONDITIONS ARE (IE SALT, COLD, ETC; DESIGN AND MATERIALS SHOULD BE MANDATED FOR BRAKE LINES NOT TO RUST THROUGH. THERE ARE MATERIALS WHICH COULD BE USED TO ACCOMPLISH THIS, PARTICULARLY FOR NORTHERN REGIONS WITH SALT ON ROADS. THE ENTIRE BRKE LINE SYSTEM IS ON THIS VEHILCLE (AND OTHERS) IS AN UNNECESSARY AND AVOIDABLE PUBLIC SAFETY HAZARD. SURELY THERE HAVE BEEN DEATHS RESULTING FROM FAILURE, I WAS LUCKY AND HAD TO MANEUVER STRIGHT THROUGH BETWEEN 2 STOPPED VEHICLES AS I HAD NO OTHER OPTION WITH NO BRAKES. ALSO, ALL VEHICLES SHOULD BE REQUIRED TO HAVE HANDLE OPERATED PARKING/EMERGENCY BRAKE LEVERS , AS THE FOOT OPERATED ONE IN THIS VEHICLE WAS USELESS, BUT A PULL TYPE, HAND OPERATED BRAKE HANDLE WOULD HAVE BEEN READILY ACCESSIBLE AND LIKELY PREVENTED NEAR DEATH INCIDENT.

ON 19 JUNE 2013 I APPLIED THE BRAKES ON A DAMP/WET ROAD. BEFORE COMING TO A COMPLETE STOP I EXPERIENCED A SORT OF HOPPING OF THE FRONT END WHILE GOING OVER A ROUGH SECTION OF ROADWAY. THIS SENSATION HAS OCCURRED NUMEROUS TIMES BEFORE AND I WAS TOLD IT HAD SOMETHING TO DO WITH THE ANTI-LOCKING BRAKE SYSTEM BUT NOTHING SPECIFIC.

MY ABS LIGHT BEGAN TO COME ON WHILE DRIVING. I COULD HEAR THE ABS PUMP RUNNING BUT THE MODULE WAS NOT FUNCTIONING. I PULLED THE FUSE SO IT WOULD STOP RUNNING AND I COULD GET HOME. AFTER TAKING IT INTO AUTO SERVICE THEY DETERMINED IT NEEDS A ELECTRONIC BRAKE CONTROL MODULE AND HAS A KELSEY & HAYES ANTI-LOCK SYSTEM. THE WORK WAS QUOTED AT OVER $700. THEY SAID IT WOULD BE SAFE TO DRIVE BUT I HAVE LIMITED ANY DRIVING WITH THE TRUCK SINCE IT VALID.

SHORTLY AFTER I PURCHASED MY 2000 GMC SONOMA [XXX] I HAD A "LOW SPEED ACTIVATION" OF THE ABS. SOME TIME LATER THE BRAKE WARNING LIGHT WAS ACTIVATED. I TOOK THE TRUCK TO A GMC DEALER AND WAS TOLD I HAD NO PROBLEMS, BUT THEY DID REPLACE THE BRAKE SHOES. EVER SINCE THEN THE LOW SPEED ACTIVATION WOULD HAPPEN PERIODICALLY. RECENTLY, THE PROBLEM HAS EVOLVED TO EVERY DAY. AND I BELIEVE THIS ROOT PROBLEM IS BEHIND A LOT OF OTHER BRAKE PROBLEMS I'VE HAD WITH THIS VEHICLE. *NM UPDATED 07/18/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

THIS HAS RESULTED IN MULTIPLE TIMES OF LEAVING ME IN INTERSECTION WITH VEHICLES SKIDDING TO STOP TO KEEP FROM T-BONING MY VEHICLE. HAVE COMPLAINED TO DEALERSHIP MANAGEMENT, GM DISTRICT FIELD REP WHO TELL ME THIS STRATEDGY IS NORMAL.
