My brakes are shot too at 40,000 km, all the lights came on. I just received my StopTech stage 2 kit with all 4 slotted rotors, hawk hps pads, ss brake lines and brake fluid for $710 US including shipping to vancouver. I have a 2004 auto so no brembo and a local tire place is quoting me about $200 to install it all.

for $4000 you can buy a whole new big brake kit (includes calipers)!

 

Contact Jeff at sales@importrp.com import replacement rotors. I got a set of authentic brembo cross drilled rotors and hawk pads for my 04 brembo coupe. All in all it cost me 1100 for 4 rotors and pads shipped to canada with duty. Then infiniti ripped me off for the install!!!!!! other than that the price is the lowest you'll find. 330/pair US for the front and 315/pair US for the rear. Pads were line 75 bucks US.

 

i had that about a week ago too..im driving in the rain and all of a sudden all the lights turn on...im just like wtf. so i went into infiniti the next morning and told them...i thought it was just like some kind of error/glitch. and they're like yeah ill get you for an appointment the following week...i was just like i dont want an appointment cuz theyd charge sooooo much extra. i just wanted to know why. and so they told me it could be the brakes. im just like o ok thanx. so i got a buddy of mine to chk it out..and i needed new front rotors and pads. so yeah i got all that done...for an amazing price. if anyone else here has the same problem. and needs to get this worked on and cant do it themselves. PM me and my buddy will be more than happy to help you out.
