My 83, 5020 brakes just locked up. Rears were locked and if 4wd was engaged fronts were locked as well. Had to tow it back to the barn. I went to start it about a month later and the brakes were no longer stuck. Any ideas on what caused this. Thanks

Not familiar with a 5020. If they are hydraulic I would say there's a return spring missing causing the pedal to sag and trapping fluid in the brake. As the fluid expands from heat it applies the brake.
