1999 GMC SIERRA — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

TRIED TO STOP WHEN SOMEONE ABOUT 50 FEET IN FRONT OF ME STOPPED. THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR AND THERE WERE NO BRAKES. I ENDED UP REAR-ENDING THE PERSON BECAUSE THE BRAKES STOPPED WORKING!!! WE HAVE HAD PROBLEMS BEFORE WITH THE ABS ALMOST MAKING MY HUSBAND GO THROUGH STOPSIGNS AND SUCH. WE TOOK THE VEHICLE TO THE DEALER AND THEY "CALIBRATED THE ABS TIRE SIZE AND RAN THE BLEED AND BLEED SYSTEM". OBVIOUSLY IT DIDN'T WORK BECAUSE WE HAVE BEEN IN 2 ACCIDENTS BECAUSE THE BRAKES QUIT WORKING BOTH TIMES! *AK
