After depressing rear foot brake the brake stays locked after releasing the foot pedal any comments would be appreciated.

there is a cam in the drum that pushes the brakes against the drum it is probaly real dry and needs some lube that might fix it i had the same problem

The brake pads may have seperated from the shoes. I would tear it apart to check. It may be a simple fix like lube that cam that wolfy said.

Thanks guys I appreciate info and will try your suggestion after I get home from work
tonight. I really need that bike running good as ice fishing will be starting very soon.
