Question No brake pedal

Well I'm not sure what to do next with this problem. Working on a friends 85 k10 with a 6.2 diesel. The brake pedal goes all the way to the floor and the truck barely stops. No brake lines are leaking. We've checked the wheel cylinders, adjusted the back brakes, and bled front and rear brakes several times. We also put a new master cylinder on it, but it still has the same problem.
I'm stumped and looking for other opinions. Thanks in advance.

Re: No brake pedal

Yup. And no air comes out when bled at each wheel. I'm thinking new master might be defective.
