How many of you guys are experiencing a soft pedal after installing the Cardone rebuilt Hydrobooster? So far we have had three bad units. The booster works but leaves a softer than desired pedal. One of the units was taken apart and inspected, everything was perfect. Well after puting it back onto the car, the same issue was still there. Keith put the new valving into an old booster housing and then they worked perfectly,which doesnt make much sense considering there is no way to alter the stock housing. They all should be the same. I'm wondering if Cardone has a spec wrong.
