I have heard that using a "torque stick" with an impact gun to install wheel lug nuts is not enough to prevent brake rotor distortion. This practice could result in the on set of brake pedal pulsation. Is this so?
Yes, impact guns have a high enough speed to cause the first nut to catch and hold the wheel at a slight angle relative to the hub even if a torque limiting socket is used. The wheel will not seat correctly and wil lcock against the mounting flange ofthe hub as the other lug nuts are tightened. The lug nut will pull against the rotor hub, stress it, which leads to brake rotor distortion. Avoid this by using a torque wrench.
