Well, is it normal that my that my rear pads are down to 2mm in 15K? I'm not racing (just driving hard ). Front brakes are OK for now. Should I go with aftermarket pads?

Thank you.

 

Normally you will wear out the front brakes twice as often as the rears. There is something wrong, if your rear brakes are already worn out. Do you rest your foot on the brake pedal while you are driving? Have you accidentally driven while your parking brake was still on.
Under normal braking the bulk of the cars weight shifts forward , this will wear out the front brakes a lot faster then the rear ones.

That's what I thought. But dealer is saying it's normal and G37 rear pads normally are replaced at ~20K miles.

 

my rear brake pads wore out twice as fast on my old audi as well. had to replace them @ 25k miles. The front ones looked almost new. I'm guessing the G is similar too.

 

Maybe the nature of the AWD cars is that rear brakes are applied much harder than the front ones?

 

The only idea I have is that I have aftermarket rims and tires (19"). Z-rated 245-40-19's probably bite harder so there is more load on breaks. Otherwise I have no other ideas.

 

It could be the brake force distribution these cars have, maybe it's applying more towards the rear of the car thus wearing them out sooner.

 

Guys. Traction control brakes the rears to stop them from spinning. That's the reason. The brakes are also small on this car which doesn't help.

I wore out my G35X brakes around 15k miles. I drive kinda fast in the snow and slip light is blinking plenty.

 

I made it to 29,000 on the rears on my 2008 G35xS...Rears should/will go first...Replace with a ceramic pads for street driving. Much less grabby than the organic compound stock pads. I changed the front to the matching ceramics at the same time.

The TSB on front rotor warp got me new rotors for the front (Infiniti/Nissan OEM of course)...Put Centric Premium rotors on the rear and used Centric Posi Quiet Ceramic pads on all 4 corners. Really like the Centrics better than stock and working perfect after 10,000 miles. Really progressive brake feel...

 

I had a set of Centrics on my old Altima and they eventually warped on the front, took a lot longer than the Bendix rotors I had on it previously, but in the end I had vibration under braking. Luckily I haven't had any warping with the Infiniti OE rotors yet knock on wood

 

Bingo!!! This is it. Yes, I like to floor it from time to time and yes, my traction control blinks almost every time........

 

Just stating the obvious but really depends on what kind of traffic you drive in and what your commute is like. If you have a commute of 50 miles on the interstate and no traffic, you might go 70K or more on a set of pads.

 

This is "old school" true. I grew up a mechanic and this is the normal train of thought. Proportioning valves use to typically be approx. 70% front braking and 30% rear. Front pads would go way before rears.

This was up until I had my 08 accord coupe into the dealer for stupid warranty stuff. They checked mechanical and told me when I picked it up that the rears were 80% worn and fronts had plenty to go. I was "WTF" all the way home. Did some poking around online and found the same thing.. that this is normal in newer cars. Contributed to all the computer controlled stuff - traction contol, stability and drivers comfort most of the time to keep from feeling nose dive.

Crazy I know...

 

mossman: That is part of It.... My 2010 G37X with 8,900 miles has 3 less mm on the pads then the fronts. Same thing happened to my 07 G35X, the rear pads wore faster than the fronts. Mnay times now, while driving on the highway, I will hit the VDC button and take off the Electronic Stability Control. I believe, that even in slight twisting conditions, wind driven conditions, the VDC will engage in split second fashion, apply brakes to the rear..... That's part of it too, IMO. Only an Infiniti Tech or engineer could really explain it. The rear brakes being "smaller" could affect the frequency & force of application of the rear brakes due to electronic brake force. Maybe somebody has info from other car forums where this similar....

Good to know. Now when I'm told my rear brakes need new pads and the fronts are still good, I wont think they are screwing with me.
