Somebody help. I replaced my front pads, calipers. and hoses and my calipers are not releasing properly from the rotors. I have blead the front brakes but I do not know if the car has to be on or off to bleed them. I still have the powermaster system. My original intent was to replace the pads. After I put them on I noticed the calipers sticking so I replaced them and the hoses. The only thing wrong before was the pads getting a little worn out. Now I am in a bigger mess then before I touched the car. Can somebody help? What could be causing this?
