Early A wit late "A" stuff!!!...Need sum help...

Ok, not too sure what you mean,. But you can check your booster by pushing on the pedal a cople of time to relieve it of air. Hold the brake down and start the car. Pedal should go down about 1 inch. If not then the booster is bad. Also have heard that sometimes the rod is the wrong size. May need to gt a longer one. Not sure if this helped or not, but I am sure someone will come along with more ideas.
