Brake Problem

I just put new brakes on the front and rear of my '95 f250 powerstroke 4x4. The pedal was a little mushy to start with so I also changed the master. I bled the system over 10 times and the pedal is still mushy and at start up in the morning rock hard. Any sugestions?
Thanks

No leaks at all. Soft lines replaced 1 year ago. Pedal is hard when backing or pulling out of the driveway and then is spongy at the first stop.

Check your wheel bearings...if they are loose it will do this exact thing. they will be fine sitting there...or if you only go strait foreward....the minute you turn at all though...then it affects it.

wheel bearings seem fine. i took it for a 15 mile drive today and tried pumping the brakes to see what would happen. when i pumped the brakes before a stop the pedal would get hard and slowly work its way down to the floor. after that pedal would remain mushy until i would pump the brakes to get it hard again. anymore ideas?
