AWD dsm, rear wheel stuck...

[john]

Ok, Update. Last time I had it apart I took the caliper off, compressed the piston, disconnected the E-brake cable, and put it back together. Pressed the brake a bit, car wouldn't roll again.

Fast forward a half a year, I need to move the car. Take the brake apart, remove the pads, car rolls back and out of the garage no prob. Go to push the car forward and nothing. Take the caliper off, still nothing. Car rolls backwards fine however.

We moved it back several time and pushed hard forward and the tire would lockup and skid on the pavement. finally the thing broke loose and seems to roll fine (for now). No plans of driving it now but any idea what the issue was? I want to fix this before I have it next time.

Whatever it was, the car could drive with the wheel locked up and not break loose. Figured that would stop any possible rust issue but maybe not.

Thanks,
John
