Wheels locking up

morning all I was out on the weekend green landing with my little jimny 
Drove over 200 miles and then parked up went to move it this morning to get the bins out and started straight away but the wheels where locked ?
if it was the brakes it surely would of came off when trying to drive it just kept starling 
Any help is appreciated 

Probably mud in the rear drum brakes

Yes, mud in the rear brakes. Overnight the mud has dried and the brake system is solid. You may have a lot of trouble getting the drums off so have the garden hose handy and run water into the drum from the top and work the drum to flow the dirt and water out at the bottom.
I converted the auto adjust to manual on my old LC and was able to slacken them off which made drum removal easy. Just a thought.

Last year I drove our spare jimny down to my daughters , about 200 miles ...al motorway , everything was fine , but after a few hours parked up it wouldn't move back or forwards , even in 4wd ...finally arranged recovery next day to a repair place ...low and behold a loud bang it it was fine ...I concluded it was the front brakes and the slide pins siezed in the out position ,, however the hand brake was never left on when parked up , though a n inspection showed no reason that it was the handbrake ....just a thought.
