Nismo Brake Failure

[RedNismo]

Car and driver's explanation of the Nismo crash points to the stock brake pads. And that after the investigation, Nissan replaced the Nismo's brakes with Nissan sport pads. Does that mean it only applies to certain nismos build after a certain date? I was under the impression that all Nismos had sport pads. I notice mine doens' really have the stopping power as my G35coupe.

I lost a stock brake line on my old 350z. I am more scared of my nissan brakes than toyota brakes

This affects ALL Akebono equipped Z34's:

Car and Driver: We now feel certain that boiling the brake fluid, which was probably made easier because most of the pad material had already melted away, is what caused the brake failure and subsequent crash at VIR.

Are you serious? I had a G35C and I can tell the Akebono brakes are better...maybe not by much but definaltly not worse.

You tell lies - the stock G35 brake setup is FAR better than our Akebonos - its a well known fact that the 2003-2004 G35 coupes had by far one of the best brakes in its league. They also wore out every 10k but still - they stopped on a DIME.

I would agree with that, the brakes were very confidence inspiring even under abusive driving conditions. They did wear pretty fast though.

Agreed. Especially the ones with Brembos including the 350z. They just had better brakes.

If you people think the NON brembo 350Z/G35 brakes are better than the Akebono, you all must be high...

That's what I was talking about. I had a 2003 G coupe with the first generation brake pads before they modified the material for longevitiy. It stopped much better than my Nismo.

So does anyone know if all Nismo's have the upgraded sports pads, or only a certain build date have them. I understand the Nissan sport pads are better than the stock akebono pads.

The NISMO pads are a dealer add-on, AFAIK.

[RedNismo]

So when they say Nismo and the sports package having better brakes just mean the caliper and the rotor and not the pads?

[tjlazer]

Typically, a sporty car can endure 30 or 40 stops in this fashion, but after seven strong panic stops, the base Akebono pads began to give way, which wasn’t surprising given our Lightning Lap experience. Stopping distances from 100 mph worsened from about 325 feet to nearly 500, a level the Z maintained through cycles two and three. By the end of the fourth cycle (or 20 stops), braking distances stretched to more than 1000 feet, pedal travel increased by almost four inches, and even goading the pedal with 150 pounds of force couldn’t produce 0.5 g of deceleration. Although the brake-pad fade was dramatic, at least it happened somewhat gradually, far more so than during our wild ride at the Virginia track.

Hmmmmm, I wonder if the Nismo Z's more aerodynamic body kit cases more break overheating than the regular 370???

It would be interesting to see the same tests run on a non-Nismo 370Z. However, C&D chose not to do that and you can't compare these tests from two different days and draw a conclusion on whether it's specifically the Nismo fascia, or the general design of the 370Z.

There are two primary issues: cold air entering the wheel well, and hot air exiting the wheel well. You can use front-mounted ducts to push and it, and have the rotor create a vortex to push air through the veins. From there you can have a slotted fender to create negative pressure and suck air out of the wheel well.

It's odd that the fascia would be so efficiently designed to push air past the wheel well entirely. I mean even if that were the case air moving past the wheel well would create suction within the wheel well, and should pull in air... maybe the chin spoiler on the Nismo front fascia is too restrictive and isn't allowing air to come in from underneath the car? I don't know if the issue is simply exiting hot air or that it doesn't have enough fresh air.

Then again, I haven't taken a physics class in a long time and should get back to work.

Er... They didn't use a NISMO to test it...
