I had a problem in my 89 SC that when I hit the brakes,the ABS and brake lights would flash.Eventually,the pedal got rock hard and the car would not stop unless I pushed the pedal with all my might.So I went and changed the accumulator with a used one.Upon removal of the old one,I noticed the old one was filled with brake fluid and I know thats not normal.Anyway,I swapped in the used one I purchased and I still have a rock hard pedal and barely any brakes?Is it your opinion that I just purchased another bad accumulator or does the problem lie somewhere else?Any info would be greatly appreciated...
