2000 CHEVROLET BLAZER — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

GOING ABOUT 30 MPH TO ENTER FREEWAY ON ONRAMP, I PUT ON MY BRAKES AS TRAFFIC WAS SLOWING. TRAFFIC THEN SLOWED QUICKLY AND I PUSHED BRAKES DOWN HARDER AND PEDAL WENT TO THE FLOOR AND CAR DIDNT STOP CAUSING ME TO HIT THE BACK FOR THE CAR IN FRONT OF ME. I CONTACTED THE DEALERSHIP AND WAS TOLD THAT WAS A PROBLEM WITH ABS BRAKES AT SLOWER STOPPING SPEEDS AND THAT NOTHING COULD BE DONE TO CORRECT IT AND THAT NOTHING WOULD SHOW ON THE COMPUTER. I CALLED A BRAKE SHOP AND WAS BASICLY TOLD THE SAME THING. THAT ABS BRAKES AT SLOW SPEEDS ARE A PROBLEM, THEY COULD PUT IT ON A MACHINE TO CHECK CODES BUT WERE 99.9% SURE AS USUAL IT WOULD SHOW NOTHING.
