*** UPDATE ***
Today I was able to go and try to unlock my brakes. I first jacked up the back (after I blocked the front wheels)until the rear wheels were off the ground. One side turned freely, the other didn't. I then went under and was able to see that the top brake pad was free but it was the bottom one that was stuck. I took my hammer and wacked the top metal part of the shoe several time and Bingo! it freed up.
Thank you again to everybody that contributed their knowledge. It was much appreciated.
Hoping that this tread may help others with the same problem in the future. That's the power of this forum
