1996 CHEVROLET BLAZER — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

FOUR MPH REAR END COLLISION. STOOD ON BRAKES AND VEHICLE FAILED TO RESPOND TO STOP. I HAVE SINCE TAKEN THE VEHICLE IN FOR A SOFTWARE CHANGE RECALL. THE BRAKES SEEM LESS EFFECTIVE THAN THEY WERE BEFORE. I THINK GENERAL MOTORS HAS HOODWINKED YOU FOLKS WITH THIS MAKE BELIEVE FIX. THE BRAKE SYSTEM ON THESE VEHICLES IS A SERIOUS PROBLEM AND IT IS NOT BEING ADDRESSED PROPERLY. I AM NEVER CONFIDENT THAT THE BRAKES WILL WORK IN A HARD BRAKING SITUATION. PLEASE HELP MORE THAN YOU HAVE AT THIS POINT. GM HAS SOME VERY DEAF EARS ON THIS SUBJECT. *AK
