I replaced the rear calipers a little over a year ago. My rear drivers side seems to be dragging. I dont think it the caliper, since if I open the bleeder valve, the caliper piston pushes in. If I dont, the piston goes no where when trying to compress it. I've read about the inside of the hoses collapsing and acting like a check valve, not letting the fluid go back up toward the reservoir. Thoughts?

That was my very first thought.

Well, the rubber hose for the brake line would be the cheapest thing to try first. At the other end of the cost spectrum is the anti-lock brake controller has a sticking valve in it. Be sure to flush the system with new clean brake fluid when you replace the hose, that way the controller may free up and not hold back pressure on that line if that is the cause. If the new hose and fluid flush does not help then look at the anti-lock controller as a possible cause.

Ok, anyone know what size flare nut wrench to use on the flare nut to the rubber hose?

Ok, turned out to be the caliper. I took the hose off and tried to compress the piston and it didnt move easily. It's covered under warranty, so Im happy. Just have to buy new pads and mostly likely a rotor.
