I went to the dealership the other day and they said that I need to change my front rotors. Is this how long they should last? I understand it all depends on driving habits but i'm pretty conservative. They also told me that I couldn't machine the Brembo rotors. Somewhat fishy.

 

if you drive around with squeeking brakes a lot then yes-- otherwise wouldn't worry about it till you feel your brake power dying.

I could be DEAD wrong tho.

 

I wish! My 2003 went thru front rotors every 15,000 miles. The newer Gs last much longer... You should feel pretty good about getting 40K out of them!
From everything I have heard and read here, the Brembos cannot or should not be turned. But that may be just Brembo trying to get more cash from your pockets?

 

Well, just looking at the rotors, they still look pretty good. I have to get a second opinion about the thickness and get them to measure it. I just don't beleive the statement that the dealership gave to me. "When you change the pads, you need to change the rotors".

 

Do your brakes squeal when you are doing just kind of creeping in traffic or something along that line? Mine are squealing now (its nerve racking)...

 

They're nuts, I just changed out my rotors recently for slotted ones, the stockers had nearly 80k miles on them, turned them once. I think I've changed my pads about 3 or 4 times tho. How the heck are you people driving?? I could probably turn my old rotors again, and they'd still be good for quite a bit longer.... go somewhere else to get your brakes checked.

 

Well, I had another problem where at 40km/h, i heard a whine coming fron the front right wheel. Almost like it was metal rubbing against metal. That was supper annoying.

As for the rotor thickness, I think they're screwing with me. I had a honda before getting the G and those rotors lasted 150,000 km. I know they aren't brembo, but still. I'll probably just get then machine and change my pads.

 

OEM Brembo rotors are softer than other rotors to provide superior stopping, so won't last as long as your Hondas did. According to some, Infiniti did that so that it would be "easier" to change both pads and rotors at the same time so you wouldn't have to remember when you did one and not the other. Take that for what it's worth. It's hard to just look at mileage though without knowing how many times you've braked, for how long and how hard, etc.

My rotors (Brembo brakes) are at almost 17k miles, and from my measurement of ~29mm (minimum is 28.4mm, new is 30mm) they are about 65% worn. I should be able to get another 7-8k out of them, though.

If your rotors have decent thickness left (which I doubt at 25k miles) then you should be able to get them machined. But if they are relatively smooth with no significant lip, then you may not even need to machine them for now - just swap pads. Also, there are also good aftermarket alternatives for rotors that may not be quite as soft. I'm looking at the dba 4000's when mine need to be replaced.

 

I need to get them measured to see how thick they are.

 

I went ~32k miles on my Brembos before changing my rotors and pads. The dealer will charge an arm and leg to replace the Brembo rotors and pads. I decided to go with the Stoptech stage 2 upgrade which covers rotors, pads, and upgrades to stainless steel brake lines. Overall, I'm pretty happy with the Stoptechs. They feel pretty good and the slotted rotors look good.

 

So if I have to change my front rotors, do you guys suggest I change the rears? I don't want slotted in the front and stock in the rears.

 

Doubt that your rear rotors will need changing at this point, but have them measured too. You could also buy non-slotted front rotors if you don't want slotted. Check out some of the sponsor sites for replacement rotors, as well as Tirerack.com, mynismo.com, Stillen.com, etc.

If you are looking to retain stock braking characteristics (i.e. great initial bite and work well when cold), stick with OEM Brembo pads. They dust a lot, but that's the tradeoff for great cold bite. Many of the aftermarket pads are designed for slightly higher fade resistance and less dust, but the tradeoff is that they don't work as well on initial pedal application, and can take a bit longer to warm up to operating temp. In warm climates this is not as big of a deal, but if it gets near freezing where you live, it makes a difference.

 

Ya, im at 32k as well and for some odd reason my stuff squeels like a bunch of horny gerbals goin at it. Actually its quite embarrasing rollin to an intersection with such a nice car and having it make ears bleed

 

DeadCellShadix, I hear ya. Feels like you're driving a Pinto when your car is squeeling like crazy!

 

Pinto..... I havn't thought about that piece of crap in over 30 years!
