Since I have replaced my brakes with 300Z brakes there is a distinct knocking/rattling from the front driver side when I first start driving the car, and then it seems after a mile it stops and all is good except under really bumpy surfaces. I originally thought that the steering knuckle wasn't ground down far enough, modified it a little more, and while some of the noise went down, sometimes it is just as loud. I used the stock Maxima cliper bolts when the calipers were replaced and these look close to the rotor and I was wondering if the 300Z bolts aren't as long as I will try that next, but need to know if they would make a difference. If anyone has any other suggestions please let me know. . .

BTW it is 93 Calipers if that makes a difference

 

No..need to...use the stock ones.

 

Nope, I used my OEM Maxima bolts.

 

I used the Maxima ones. I heard the Z32 ones are actually longer...

 

me too.

 

the Z32 ones are shorter... but don't worry about that. if they hold the caliper on the car, then they do their job. it's not going to make a difference which bolts you use0 just make sure you got them torqued to spec.

 

Thanks guys. . . I think I have now traced my noises to something in the strut tower. . . strut tower moves WAY too easily. Seems like a bearing problem. . . may need to replace the bearing and see if that helps.
