I have replaced the front rotors, calipers, pads, etc. While bleeding the brakes I can not get the passenger side caliper to move at all. I am getting fluid through the lines and it bleeds normally, but after I close the bleeder valve and try the brakes the caliper is not moving at all. I pulled everything apart and was able to move the piston on the caliper(thought it was seized) any ideas what is going on? I am beginning to belive it is in the abs system, maybe a bad check valve? Any help would be greatly appreciated. Thanks in advance.

Check the brake hose on that side could be collasped internally acting as a one way check valve before you decide on the ABS unit-

Thanks for your reply, when I removed the line, whomever had done the brakes last had a twist on the line and I am thinking it might be collapsed. If I hold it in the twisted position, I get more fluid dripping than if I have it straight. Thanks again.
