Answer :
Unevenly torqued wheel lug nuts or bolts can cause C) rotor 'deflection' and actually induce run-out, even after using the Pro-Cut lathe properly.
This happens because when the lug nuts or bolts are not torqued evenly, it causes an imbalance in the rotor system. Even if a Pro-Cut lathe is used properly to machine the rotor surface, the uneven torque can still introduce deformations in the rotor, leading to run-out, which is the tendency of the rotor to wobble as it spins. This wobble can lead to vibrations and decreased braking efficiency.
