Have replaced booster, master cylinder, pump, lines, calipers and all pads and rotors are new. All parts were from ford, brakes bled multiple times, cylinder was bench bled properly. still brakes are spongy, cylinder was replaced two times, both from Ford with no change in performance.

You listed "pump", so I am assuming you have anti-lock brakes. The hydraulic controller on many models needs to be bled with a scanner. That will tell the ABS computer to open a pair of valves so air can be bled out of those chambers.

The pump was replaced at the dealership, so I am assuming they did it correctly.

If they did that to solve the low brake pedal, what was their reaction to giving the vehicle back without solving the problem?

They said, "everything should be fixed and the brakes are working well" then charged a $1,000.00 for no change in performance.

Hello,

I would start by using three vise grips and gently close the three rubber brake lines to each front wheel and the one rear. Once closed step on the pedal. It should not move at all, if it does then the problem is up at the master, if not the problem is down at the wheels.

Let us know.

I hadn't thought of that, so if it's at the wheel should I just move the vice grips around until I find the one that lets the pedal go down?
