    Out of adjustment?
    Drum wraped?
    Shoes and drum glazed?

    adjustment is good, drum looks fine, put wheel back on drove it and it was fine then it locked up again....touched the brake pedal and it came free then it would t still would lock up hit brakes again and would free up then lock up again etc...

    Was the wheel cylinder leaking? Is the axle seal leaking? If the linings aren't clean (new) after a leak, you will still get a lock up condition from my experiance.
    When were the linings changed? Are they installed correctly (primary facing forward, secondary facing rearward (both sides)?
    Is the parking brake fully releasing?
    Lots of possibilities...

    all the above..

    resurface the drum and sand, or replace (preferred) the shoes, try it again....

    How are you adjusting them? How much drag on it

    went over to talk to mechanic he said it was odd thing also. he said check other side and compare did that and one side was different. pad was off a little. put it back in to place and now its fine. also changed brake line since it was rusty. the good thing is it did not happen in a snow storm ha.

    So the primary and secondary were reversed. Easy mistake to make. Glad it turned out for you.
