Any difference if you pump the brake pedal like a mad man?

| The van has sat since any work was done - like September last year.
|The brake fluid was changed. It was nasty. It may need to be
|changed again - but I wouldn't think so. But, whatever it takes......
|
|Perhaps even the rear brake cylinders need changing out -
