You don't need to compulsorily turn the rotors every time the pads are changed. Turning is required only if the rotor (or disc) is warped, badly scratched or heavily rusted. Smooth concentric circles are usually normal unless heavily ridged (and this requires turning). Remember though that turning the rotor many times will eventually require replacing it as there is a minimum safe thickness to which is can be turned. Any thinner will warrant replacement.
Yes, the Infiniti g35 and the G35X use the same routers.
remove tire calipers brake assembly then pull your rotors off i would recomend putting new brake pads if your putting new rotors you will need a special puller for the rotors cause they are pressed on
resurface/replace front rotors. probably do the rear rotors too
Your Brake rotors are warped... Remove them and have them turned or replace them.
You need to polish the rotors twice per month.
The brake rotors are warped. Someone tightened the lugnuts out of sequence. That compressed and torqued the rotors out of spec. Replace the from rotors and pads and the rear ones too, if necessary.
1-3-4-2 rotors turns counterclockwise.
You can purchase break rotors online at Rotorsonline.com. Putting on break rotors is a little time consuming. You will have to take the tires completely off to put the rotors back on. It will be good if you had a vehicle lift or a really good jack.
Excessive or heavy and continuous braking may warp brake rotors. Braking hard (heating the rotors a lot) and then going through water (which quickly cools the hot rotors) may also cause the rotors to warp. If the brake pads or brake rotors are getting thin, the rotors will warp more easily.
There no way to prevent them getting hot unless you don't brake
Unbalanced tires 99.999999% of the time. rotors bad (get them turned at any parts store) ball joint bad from wear, axles not balanced on shaft to housing, but most likely rotors from improper mechanic work like putting brakes on a bad rotor without getting it turned down...
Warped brake rotors/drums.
