My 2002 Odyssey is dragging it's brakes and I have replaced the caliper, but the problem remains. I've cleaned and greased bolts and anything I can think of that could have friction. I tested the caliper off the bracket and the piston comes out and resets itself when the brake pedal is depressed. But when I mount it back on the bracket the caliper piston doesn't seem to want to reset. I've looked for pinched hoses and can't find anything. I've bled the brakes already so that's not the issue.
