Honestly, I can live with it but it's still a bit annoying. I've taken my Nismo to the stealership and they said there is plenty of pad left on all four sides and that it's a byproduct of high performance brakes.

Believe or not, I'm actually inclined to agree. I've heard GT-R, IS F, CTS-V, et. al., owners complain about the squeakiness of their Brembos so it can't be an isolated problem. But just to be sure, I wanted to ask you all, do your factory Brembos squeak despite having a lot of pad left?

 

Mine do it too from time to time...I wouldn't worry about it.

 

Stock pads should not squeak. You could lube the backing plates. Mine do not squeak unless I run race pads that get unbedded or they are on the metal warning tab. This is with 80,000 miles of experience on them, including a bunch of track days.

 

I've never had any of the pads on my Z squeek either. OEM non-brembo, OEM brembo, Autozone Generic or Endless.

It could be dust buildup - do you hit the pads and caliper with the hose when washing your car?
