This is a new one for me.

After I just finished therapy for inhaling radioactive metallic particles, I find my front brakes are hardly worn. What would cause a rear bias?

 

I've noticed the same thing on my 07 Z 8k miles only? What the hell is going on here

 

It definitely wasn't like this when I changed the brakes the last time. I have an 04 with just over 100k and I've felt like it wasn't stopping as fast or the same as it used to.

 

I've always assumed that the front bites and the rears ride on the rotors a little longer?

 

Moar info on inhaling radioactive particles please!

 

The fronts take the majority of the stopping force, so the rears should last much longer. I had the same problem on my 04. Actually it was just the right rear. It was down to near nothing. I took it to the dealer with my laser thermometer, and showed them the temperature difference. The left rear was about 175 degrees and the right rear was at 315 degrees. They couldn't figure it out so they just replace the rear caliper all together. No charge.

Just poking fun at myself.

 

@ 350Catfish

It's possible that's it, but that would mean both of my rears went bad at nearly the same time. I think something else is going on here.

 

Damn u guys got an 04... I guess i must driving holding the brake pedel ..
I noticed the rears low when switching out to new wheels

 

It was the same with my 04. The front pads lasted 42k the rear like 38k. Wierd.

 

I have between 35k and 40k on both the front and the rears. However the rears are gone and the fronts actually have closer to 75%.

 

with the yaw sensor and vdc it applies brakes to the rear to counter the back swinging out. you ragging it around corners and having vdc kick in a lot?

 

After a track event last year I had to same problem with the rears down to the metal backing plates while the fronts still had half+ material. I only was able to get 9000 miles out of my pads. Oh and this is on the base so no VDC, must be heavily rear brake baised.

 

Not sure about this car but I had the same thing happen with my accord, dealership told me it was normal because the surface area is smaller than the fronts, not sure if its true.

 

Historically for at least 24 years* Nissan has used a higher than average rear bias and softer rear pads to squeeze the final foot out of braking distance tests.

*My Personal experience 85z, 88 pathy, 90z and 90Q45 driving ~500,000 miles in Nissan.
Not to mention working on many thousands.

Since VLSD was deleted and replaced by rear brake traction
slip control the rear pad wear problem has only INCREASED depending on agressive driving.

 

This is pretty normal on the 350Z and G35. It does seem it has some higher rear brake bias.

 

I have owned a lot of Nissans, my list is below, and never seen this problem till the G35/350z. The rears always last twice as long on others.

Strange. I just a full brake job on my 04.5 and there was similar wear in the front and the back. Maybe your calipers seized? I've had both rears seize before but it was on a much older car.

I doubt that the car was factory designed to have the rears wear out way sooner.

 

It's a known issue on the G35/Z since they have been out.

 

Damn i will have to check out my rears then. i just replaced my fronts at 32K but never bothered checking the rears because I figured the fronts would wear out long before the rear.
