It shouldn't be any smell. The problwm most likely in a brakes system. I had exactly the same problem not so long ago and when i tryed to fix it, i found that my rear pair of brakes wasnt perfectly fit. It was placed well but the gabarite clip on the brake pads was a little smaller that the holders. It would make them make annoying sounds and not stop your car propperly.
Hope it will solve it.
Dont piss me off. I am running out of places to hide the bodies
