Ok gents, here's the deal. I've got an '08 F150 and it has started shuddering coming to a stop in the last couple of months. I figured the front rotors were warped so I yanked off the tires and put a dial micrometer on the rotors. One side has about a 0.001" runout, the other has about a 0.005" runout while rotating the rotor. Is that enough to cause the shudder? I measured the thickness and they have enough meat on them to get them turned. Suggestions? Getting them turned is ~$15/per rotor. Replacing them is ~$85/rotor. I checked one of the rear rotors and it was about .005" of runout too.
