Ok, what you can do is jack up the rear of the vehicle, spin the left rear wheel if won't spin try opening the Bleeder valve on the caliper. If brake releases then most like to brake hose has failed and will need to be replaced.
If doesn't release then could be the caliper sticking or the caliper bolts/slides are sticking and just need to be cleaned and relubed.
