Duster Brake Pedal Freeplay

I have had this issue for a while on my Duster. I have almost 1.5 inches of brake pedal freeplay. I have measured and adjusted master cylinder pushrod to recomended .020 gap. Still the same so I adjusted pushrod .020 the other way giving it a little preload. Still the same. From what I can see the pedal at top has a bushing that swings on a shaft so nothing really can be causing this issue at the top of pedal. This is not a bleeding issue as I have bled the brakes and brakes work.

How much brake pedal freeplay should it have and do members rides have the same. It slops around like a spoon in a tub of custard.
