First Problem With my 370Z

Chuck33079 · 06-13-2013, 12:11 PM

Could it be, and it just gets mistaken for the other vibrations coming from the rotors?

Oddly the pedal doesn't really vibrate that bad at all. I'd say about 25% as much as the wheel, unless my Piloti driving shoes somehow insulate that and nothing else, lol

I've felt ABS before, and there is nothing like that going on.

The ABS pulse on this car is the weakest I've ever felt. I honestly didn't know I was in ABS on the track until I ran the pads down to the backing plate and could feel the tiny tiny little bumps on EVERY stop.

Well, maybe so, but wouldn't the dash light up? I've seen/felt it it provoke a bit on gravel, so I figured I would notice it.

Regardless, my pads are not being worn down. My factory pads came off but a few hundred miles ago, and had tons of meat left on them, even after the dealer shaved them previously.

If the unit was bad, there's no guarantee the light would go on.

It does go on when I provoked ABS on a gravel road not long ago, but I don't have a clue, or I would have told them how to fix it, so I'm not in a position to debate it, really. I do know the stock pads were not very worn down at all after 20K miles, just glazed.

I'm just going down the list of parts. The electronic stuff was just about the only part of the system that hasn't been replaced.

I have no idea. Dealer has no idea. Nissan Corporate has been contacted. The only other variable is the driver, and I'm sorry, you don't get 17K + miles out of the factory Potenza's and have the same amount of pad left on the front as you do the rear pads, if you are beating on the car excessively enough for it to legitimately be the driver's fault. Especially warping them 4 times in 22,XXX miles.

So I have no clue what it is.

This is the only issue I can find with what you've described about your driving, and it doesn't account for the severity of the warpage or the fact that you said you toasted a set in one panic stop. If you said you had a "little" vibration, I'd point at this as the cause. You're way past "a little vibration".

It's a normal daily commute with 1 red-light at the end of an off-ramp in 2 locations, both with a gradient. What exactly am I expected to do about it? Throw it in reverse and rock the car backwards until the light changes? The car should be able to handle it.

My Z06
My WS6
My G20
My Kia rental

They did just fine.

Also, yes, that toasting them in one panic slow (I did not even stop) has me seriously puzzled. That was the start of the whole thing at 10K miles. A panic slow from normal freeway speeds as someone moved over into my lane.

I was pretty clear about the fact that I don't think that's a contributing factor to your issue. When I'm in that situation though, I use the handbrake.

I understand.

Handbrake. Doesn't that just manually activate the rear pads on this car? Regardless, I will use it in the future, but like you said, I seriously doubt this is the issue. The brakes never really get hot by any measurable sense. I mean sure, I wouldn't grab one, but they never smoke and their surface is shiny and bright, no blue spots, etc. I just don't heat them up much I don't feel.

Handbrake is inside the rear rotor drum.

Chuck33079 · 06-13-2013, 12:58 PM

It's a separate brake, kind of like a little brake drum. Either way, that's not the issue. Something is majorly out of whack. The abs unit not releasing pressure for some reason was the last thing I could think of.

ImportConvert · 06-13-2013, 01:01 PM

Well, I hope they either sort it out, or buy the thing back, and don't drag it out one way or the other. I would like to get back to commuting.
