Strange knocking noise

[nick9802]

Whats up my Nico fam. I have a new problem. My car vibrates very hard when when I brake from fast or slow speeds. My father is a mechanic and said that all I need to do is get the rotors turned and that would fix it. I have had rotor problems on other cars I have owned and I never felt a vibration like that. I look through the Nico J30 forum and I haven't found anyone with this problem. Help!!!

P.S. I need a A/C tension pulley and can't find one anywhere. Any place I can get one that ain't from Infiniti?

P.P.S. I have seen that squeeking noise is a very common problem with J30 owners. I recommend that you check all your pulleys and see if they are turning.

Yes its teh rotors, they are warped, doubt you could turn em to optimal outof round.

Just get new rotors and pads, and some good brake grease.

That sort of vibration can also be symptomatic of worn struts, especially with aftermarket wheels.
