Remmove the rear drum to see if the brake shoes are wet. If so it will either be wet from leaking brake flud [caused by a bad wheel cylinder] or wet because of a leaking axle seal. This contamiination can cause the wheel to lock up during braking.
Let me know what you find because there are a couple of other causes, but this is a good start.
