Need tech help w/ 2007 Ram 1500 fr brakes(long read)

every one here has a valid point and opinion.here is mine.if the rotors need to be turned my question is how much needs to be cut.if ther is pulsation that means they probably have at least .0400 run out.now they are warped and by turning them they now are even thinner and will warp again in a very short time.i run a independent shop and i say the customer makes the call turn or replace.if it is explained up front to the cutomer and they decide to turn them and they warp again that was his choice.if they decide not to turn the rotors ,again that was there choice.if there is problems it was all there choice
