Brakes not working well

[rsk68]

Well i'm still working out the bugs and brakes are one of them, I have Willwood 6 piston fronts and 4 piston rears with a Wilwood 1" master cylinder, the pedal is rather hard and feels like it just isnt stopping the car, like theres just not enough pressure, i vacumm bled the brakes and cant remember if i bled the MC, any suggestions on what i should try or look for, i also have there praportioning valve but its screwed all the way in for an open circuit. I guess the first thing i should do is bleed the master due to i cant remember if i ever have.
