yes. spot on. good.najib, when was your last time washing your car ? did you apply handbrake. If so I think is your rear brake shoes is sticking to the drum. the rear tyre can move right ?
This often happen when you finish washing your park and your drive into the porch and park it. Because the brakes shoes and drum is wet so is will rust overtime and it just jam but dont worry nothing big will happens. try to get your car to rough surface and put into gear and let it move it will break free.
Worst case is the brake shoes pad will break off from the tapak only..but you will need to change to new shoes...I have this problem before with 206 before convert to disc. To avoid it...after washing the car drive it around to heat up the brakes and free it from any moisture.
drive around and brake... when friction occurs in ur brakes, it generates heat... which then heats up the brake and dry it up from any moisture...btw, how to heat up the brakes?
