OK, fixed the problem. Some how the brakes became contaminated. there doesn't appear to be a leak, but after pulling the brake drums, it appeared as if the brake dust was sticky as are the brake shoes and drum. I cleaned out the brake dust, sanded down the brake shoes and sanded down the brake drums. Now all is back to normal. After cleaning I checked for leaks and there didn't appear to be any so I don't know how they got contaminated.
