08 G 35x Brakes gone already

[hockeygamers.com]

I did a search and couldnt find anything.I own a 2008 G35x. I am original owner and now have 22,000 miles. The breaks are bad (rotors). There is plenty of pad left. I get the shimmer when I brake. When I hop on the gas the break light flashes on as well.

The dealer said its $600 for the front alone. Are rotors not a waranty item? Should they go this fast?

Reccomendations on replacement? I dont see why I would replace with dealer when they are going to go in another 20k.

Any help appreciated!

I think Infiniti screwed up on the X & XS. I am the easiest Brake & Clutch Guy on the planet. I have an 08 G35XSI had to have the rear pads replaced at 40K mi. and the rotors turned. The tech said i still had 60% on the front pads ?? Must have a LOT of rear brake bias ?? Now at 60K mi. Both my front rotors are warped and I still have 30% on the front pads. I am trying to find aftermarket slotted rotors and nobody seems to know where to get them. Infiniti tells me the rotors for the XS are diff. than the X. but they dont seem to know what the diff. is. It has something to do with the AWD sensors. The brakes on this car seem to be its weekest link, and nobody seems to have a fix except OEM, which in my estimation is Subprime or just plain CRAP. I think you can find slotted rotors for the X at Power Slot and go with a GOOD ceramic pad or a Good Street/Track pad, and it may solve your problem. Good Luck ! Jerry Collins

On a street car I would go with solid rotors and a set of quality pads. You must drive alot for 60k so early.

I am paying attention to this on my 08 XS. Mine don't shimmy but I do notice that they do not seem to be as silky smooth as they were. I have about 15k and like the poster below brake gently since I don't like to be jerked around like a ride at the fair.

If you have normal brake pad wear I think I would push for a warranty item replacement of the rotors with such low mileage.

One thing I do which I feel most do not is I rotate my rotors when I stop for any length of time. That is after a complete stop I roll the car forward a couple of times so the rotors are allowed to cool more evenly, something some vette owners do.

Hi Pfarmer. Have you had any luck finding any suspension upgrades for the XS.? Do you happen to know if the standard G35X has the same rotors as the XS ? I can get Italia rotors for the X, but they list nothing for the XS. The Infiniti parts Guy, is no help at all. He didnt even know they made an XS. Anywhere from 200mi a day to 350mi. I use this as my work car and I am busy, busy, busy.! I have run the slotted rotors on my last 4 cars and I love em. Never any probs. And an occasional Track Day or Autocross, they are much better than the OEM. Jerry

I don't believe the S on an X gives you anything in the way of brakes such as is the case with an S on a non X will. Best not ask the parts guy about the tech package on an XS, I found 4 for sale when I bought mine in the entire country.

There are techs on this forum who can probably look up the OEM pads to tell you if there is a difference with the XS over X when it comes to pads. I have been led to believe the rotors and the rest of the components are the same.

On a street car with modern brake pads I see little use for slotted or drilled rotors with the possible except of rain conditions with drilled. Vented rotors I have a better feeling about. One reason I state this is that both drilled and slotted rotors benefits sit largely around a non-existant problem with modern brake pads which is outgassing, hence they were referred to as degassing holes in the case of drilled rotors. This is not to state that the OEM rotors can not be improved on which in this case is aftermarket solids.

Many race cars now lean more towards just larger brakes over drilled or slotted. Both types tends to wear pads faster with the consensus seeming to lean more towards the slotted wearing the pads. That is one reason I state 'On a street car'. I have seen a few studies dealing with temperature and most seem to find that there is little to be gain based on temperature.

As far as mass and temperature goes the greater the mass generally the greater the temperature that can be stored however the greater the mass the slower the heat is given up, so type of brake use, track type for racing purposes, etc. all come into play. I would think that a lower mass rotor may well allow the transfer of energy to occur quicker, that is friction to heat. But a lower mass will allow less energy to be stored. So for short stops a lower mass rotor may actually stop a vehicle quicker. Repeated stops however may not since the lower mass rotor reaches it limit quicker.

On the other end of the snake however is that the lower mass rotor may recover quicker which I would think translates into the ability of handling more rapidly reoccuring short brake use. This is a hot topic in many ways and I believe one reason is the endless variations in brake use.

Our 05 sedan rear brakes were gone before 30K miles. (not used to seeing rears wear out before fronts!!)I replaced them with CMax ceramics.

The front rotors are warped, but the pads are fine.

I've replaced the front pads on my 04 coupe with Akebono pro-act pads and have been very pleased. When I bought the car (used), it had Nissan pads at the corners and they squealed like a pig and produced tons of dust. No dust, no squeal and I didn't even have the fronts turned.

So, when it's time to do the front pads on the 05 sedan, I'm going to get Napa replacement rotors (I get a discount there) and Akebono pro-act pads. Until then, I'll just put up with the pulsating.

The brakes on my 08 X are also gone. I just passed 17k. Went in for the 18 month check up and they said they need to be replaced and my rotors are warped. Bummer. But I'm taking the opportunity to get an aftermarket setup. Options are very limited though from what I have been reading on here

I have wondered in the short time I have had my G35 Coupe how much brake wear the Traction Control/Stability Control adds. It would seem logical that if the system uses individual brake actuation to control wheelspin or to control lateral movement, the more you use these systems, the more brake wear that would result.

Any one have .02 on this idea?

Hello,

I wasn't very happy with the rotors on mine either. It had 60k on it when I got the car, It quickly developed unreasonable shake when braking. I just put on new rotors. I found a buy one get one half price sale on a set of better than stock parts. Best investment in brakes I ever made. I now have confident, positive braking at any speed. They are easy to put on. I won't waste money getting them machined again.

I've had a different experience on my 2007 "X". At 33,000 miles I replaced the front pads only with EBC's Redstuff. There was no indication of wear from the wear indicators; I've just never gone that long on a set of front pads. The rears are still going at close to 40k with no noise. I'm in stop and go traffic every day, too. Can't explain it, just the way it is.....
