Another thing to test is if the booster is actually working, Booster Dewey does nice work but things can happen.... With the engine not running pump the brake pedal a few times till the pedal is high & firm with no vacuum stored in the booster... Start the engine... Does the pedal fall slightly? If not the booster isn't working....
