My 1995 e320 has this high pitched squeel that only comes out at low speeds (usually below 10). At first I thought it to be my brake pads, but I looked at them and there is hardly any wear. The odd thing about this is that I had replaced the front rotors and put in all new pads recently. Whenever I stop and happen to have the radio down, it seems that the squeel comes from the front brakes (the ones we already replaced). If anyone has some possible causes or solutions I would appreciate it.
