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

I HAD TO MAKE A "PANIC STOP". I PUSHED THE BRAKE PEDAL AS HARD AS POSSIBLE. FELT THE VEHICLE SHUDDER SEVERAL TIMES AND FELT WHAT I ASSUMED WAS THE ABS BRAKES CYCLING, THEN THE VEHICLE JUST ROLLED FORWARD...NO BRAKING AT ALL WAS FELT, RESULTING IN A REAR-END COLLISION. I KNOW THAT IF I HAD PROPERLY FUNCTIONING BRAKES, I WOULD HAVE STOPPED IN A SAFE DISTANCE. WHEN I FELT THE DECELERATION STOP, I PUSHED EVEN HARDER ON THE PEDAL, WITH ABSOLUTELY NO CHANGE IN VELOCITY AND NO MORE ROOM FOR THE PEDAL TO MOVE. THERE WAS AT LEAST 15 BETWEEN VEHICLESAT THIS POINT,&..I COULD /SHOULD HAVE STOPPED SAFELY, WITH NO COLLISION IF THE BRAKES HAD WORKED PROPERLY! *AK
