Please help brake problems!

[mark21810]

Hi I have a 94 ranger V6 4L. I have absolutly no brakes. I have looked at the trouble shooting in the tech libary but nothing helps. I have replaced brake boost, master cylinder and front calipers. im not loosing any fluid anywhere and brakes have been bleed. When i apply brakes the pedal goes right to the floor. If brakes are pumped then they do work for a very short time but other than that they do not work please help. Thanks

Sounds like a bad master. Did you bench bleed it?

there is a new master on it and no did not bench bleed but there is new fluid that flows out of every line so no air bubbles.

Air gets trapped in the MC anyway. Bleed it right at the MC connections.

Also, wouldn't be the first one I had seen bad out of the box.
