07 expedition EL 4X4 Brakes not releasing
I have just recently put new rotors and new calipers on the front of an 07 Expedition e l 4 x 4 and after completing the job when you hit the brake pedal the brake calipers do not release I can crack the bleeder screw and then they release

Do the rear brakes release? ABS? The flexible hoses could be the problem. Sometimes they collapse on the inside. Both probably would not fail at the same time? It could be the master cylinder. When the brake pedal is released, a spring in the MC pulls the plunger back and uncovers a hole that allows the brake pressure to be relieved back to the MC resorvoir. If this hole is plugged, the pressure can't be relieved.
