Rotors bad?

[huntnut]

When I tore down my frontend to change ball joints and hub bearing I notice on my rotors there were little black spots ate into the rotors, but only on the back sides. What would do that and should I think about changing them. Other then that they look good. Should I have them turned down?

Hotspots.......Are they shakin or thin ???

As long as they are not warped and there is still enough material I would turn them down.

Yea there plenty think, I did have a vidraion when braking but I think that was the bad hub bearing and ball joints. Never felt anything in the pedal

When my rotors are warped (which all four are right now) I don't ever feel it in the pedal, but the truck will bounce and I can feel it in the wheel sometimes.
