Only after a month I notice that it is not the others, but my 451 year 2007 Smart.It squeaks somewhere(not always) while driving slower in the zb.1 course. Of course, I first thought about the brake drums in the back as the previous owner gave me this new at the sale.It just provoked the noise again and when I squeaked at 10km/h and pull the hand brake a few times then it slightly changes the noise. Just got out and fingers to the rims in the back. Left was not even lukewarm and right already very warm, the brake drum itself should be hot. Must be clear, or? because the engine is running the heat out somewhere right brake drum, which I don’t believe.What do you think?
