When I had the alignment/steering knuckle job done at the MB dealership, they alerted me to the fact that my front brakes need attention. Specifically, they told me that not only do I need to replace pads/rotors but also that the wiring harness at the pad wear sensor has been damaged by someone who, they think, did the last brake job improperly. They told me this is why my pad wear sensor is not lit, while it should by now.

Anyhow, I've been riding on these brakes for 3+ years, and the front rotors look perfectly smooth even now.

I'm not really comfortable doing the front brake rotors myself, after reading about packing the bearings and setting tolerances, etc... I was hoping they are as easy as removing calipers, bolting off the rotors, and bolting new ones on like in my old Saab, but they are not, obviously... I can't really afford getting the new rotors and especially paying someone to do it right now. So instead as a *temporary* fix through the Winter, I was thinking about just replacing front pads and perhaps the sensors/wiring if that is easy. What kind of rotor thickness can I get away with on '84 300SD, at least for several months on new pads?
