have someone coming to look at my car tommorrow. however i have had it parked up for 3 weeks (handbrake on not a good idea i know), went to reverse it this morning and herd an almighty clunk no when i drive the car around it seems to be like driving around with the brakes on any ideas what to do?

 

try applying the handbrake while driving slowly a couple of times should wear the rust build up of the handbrake drum as it sounds like the shoes where stuck to the drum
