I just changed my drivers side front rotor, pads, and caliper because the inside rotor was pitted and it seemed like the pistons were freezing up. After i was done, i bled the line. I got in to test drive it, and it still feels like the piston is locked up. I jacked up the tire and it is difficult to spin. And it comes to a halt as soon as i stop spinning it. It will not spin with just momentum. What could i have done wrong, or what else could be the problem here? I used all tne new hardware that came with the caliper including the slide pins.
Thanks in advance for any help

It is normal for the pads to drag on the rotor. Drive it and check it again after you put on a thousand miles.

The disc has a natural warp to it, that is what pushes the caliper free, if the caliper is not free to retract, easily it will keep preasure on the pad. Since I retired I am doing a bit of automotive repaires, I gave up on doing the brakes if I do not do the Calipers. I clamp the brake line off, and back off the bleeder, if it takes any great effort to push the pistons back, I replace them. Calipers are really cheap. My favorite is the Power Stop kit from Rock Auto, you get the discs pads, calipers, and rotors drilled and slotted cheap, I put a set on me GMC, they work great.
Just a thought!

The hose to the caliper may have an internal defect, or the master cylinder may be bad.
