hello rohan
lookin good , thats great to see you have finally got the old girl going and looks like you have a bit of space out there at wanneroo.
if you havent already worked it out with the above information then maybe i can help.we had the same problems with ours and this is the simple way of fixing it

feel the back hubs and more than likely they are too hot. if so then this is also the reason the motor is overheating as the motors trying to push you with the brakes on.
you have top and bottom adjustment for the brakes so back off which ever you think is too tight. if your carrier rolls forward once you have hit the clutch this is good as it means there is no pressure on the brakes. the trade off is you loose steering so adjust as per specis and a little trial and error and you should get a happy medium. if not then sorry but the hubs got to come off and you may find linkages rusted up of the pads are worn out.

good luck

cheers
