No Brake Pedal 2004 GMC Safari Van


Got a 04 GMC Safari with no brake pedal. I replaced master cylinder and its the same. It has power steering assist brakes and antilock. No light on for antilock or just brake and yes both work. Is it possible that antilock some how bypassed the pressure. Or is power steering assist bad? Pedal goes to floor with no resistance. Thought if bad assist pedal would be rock hard.

Did you bench bleed the new master cylinder before installing it?
