Chevrolet Repair: puzzled, four wheels, brakes

Question
I have a 85 chevy 1ton with no brakes. fluid is full ,I tried to bleed the brakes and no fluid came out, I tried all four wheels but still no fluid what seems to be my problem

Answer
Hi chris... check the brake shut off valve to see in it is stuck over. there is a pin on the end of it make sure it is centered. bleed the farthest wheel away from the master first. keeping that pin centered...if nothing happens that way try bleeding the master first....then repete this process... hope this helps
