Vehicle sat for a while. All lines were rusted and shot. So I replaced them. Had 2 blow out. So i just changed them all. Is there a way to check the valves?

 

Sometimes you can get lucky and free it up by tapping on it lightly with a hammer. Otherwise you're probably taking it apart.

 

Ok I'll see what I come up with. I did put a different one on. Thay did have good pressure and brakes. And I'm having same issue still.

 

See which end isn't getting fluid. (just crack a bleeder open, and have someone step on the pedal.) Once you know that, have someone pump up the brakes, and hold pressure, then, open one of the bleeders on the opposite end. That should shock the valve back into place. Might require a couple shots to get it to move.

 

Every line has fluid just no pressure.

 

Failed master cylinder?
