Brake rotor resurfacing.

[Grant Lenahan]

I worried about this too. But careful sanding, as i described:

1. removed pad deposits that other methods had not
2. removed a lip that was preventing pad seating
     (note: i also went around that lip with a screwdriver, knocking  
it off)

So the point is, it can work. I agree you can also make matters  
worse.  I suggest trying it.
