I tried to change the rear brake pads but ran into a major roadblock. I was not able to push in the caliper pistons, tried both sides. After buying a special "push", tool and having no success with it, I went to a different parts store. I then found out that you need to "screw" in the piston instead of pushing it in. I went and bought a metal cube attachment that you put on a ratchet with extension. (is this correct tool?) I kept screwing it in but it only went in less then a 1/4 of a centimeter, if that. I tried calling Ford and they said that I need a special tool that enables you to turn and push at the same time? Has anybody had the same problem? I would appreciate any help. It was simple to remove the old pads and put new ones in but I cannot make the piston move to enable the caliper to fit over the pads. Is there a trick to this? Doe I need to turn and push same time or align the piston to a certain spot before push?? Help please!!
