Yeah, but. A pinched or collapsed brake hose can cause the pads not to retract. A corroded slider can cause the same thing. Or the piston can be hung up, usually corrosion in the caliper cylinder. All three have the exact same symptoms.
When you first jack the tire off the ground, it will be hard to turn if any of these have occurred. Crack the bleeder a full turn, just tap (don't push) the brakes, and see if it still happens. If it doesn't, and it is just one wheel that holds, you have a bad brake line.
As you pull the pads out of the caliper, see if they slide easily. Not the pistons, just slide the pads to the inside. If not, look for dirt or corrosion that may be holding them up.
When you pull the caliper off, see if you can retract the pistons, one at a time, with a large pair of channel locks. If they're not smooth, you need a rebuild kit or a new caliper.
Good luck,
Mark

I just went through this. I suspected either a bad caliper, or a bad hose. I was pleasantly surprised to find corroded sliders. I was told these calipers rarely go bad when I was pricing them at the dealer. Good luck, Rob
