yeah I think he is right. I would give it one last shot with the oem parts and do a full brake flush on the car before writing Nissan off. It could be the technicians that are incompetent and not necessarily your driving characteristics. Hope that this problem can get resolved either way so that if it happens to another forum member we can use this as a learning lesson.

I was thinking of going with a upgraded rotor/pad set but after seeing some of the stuff import has gone through I am definitely reconsidering that thought.

Hey import if you have time try to jack the car up and rotate the fronts. Pump the brakes a couple of times before that to see if it seizes. also check the quality of the fluid.

Never even bother visiting LA is my advice. It's a crap state in EVERY WAY POSSIBLE.

Couldn't disagree more. Yesterday I bottomed out on the 405...I still love this place. Do we have our problems? Do some of our roads suck? Did our ball team choke this year? Yes, Yes, and Yes. But like Ice Cube says..."there ain't nothing else like LA." There are many, many worse places to live than on SoCal...especially for a car guy! Not trying to start any ****, just offering a different perspective on our great state and city for anyone not familiar with it.

He's talking about Louisiana, not Los Angeles

I'll never own another American car. Reason 1 everybody has one 2. re-sell is crap.

1. I agree, my state sucks. This might well be the problem. It's why I'm leaving. I have some Class III stuff pending with the BATFE which is why I haven't already. After my SOCOM suppressor and 300BLK SBR clear, I'm gone.

2. Everyone has one...for a reason.

3. I'd like to keep a car until the wheels fall off for once. I've tried doing that with my past American cars, and it happens at well past 150K miles or so when I normally sell them. My import lost its transmission, motor mounts, and a host of other things at around 100K, and this import hasn't made it past 10K before having issues that are still plaguing me at 20K. While looking at SRT products, and remembering what I sold my 'vette for, and looking up KBB on this 370Z, I strongly refute your statement about holding value. The 370Z doesn't for **** compared to other domestics that I have owned or that appeal to me.

You're talking about LA. It's nice there except the crime and politics. Here in my LA, even the crime and politics are glossed over in favor of bitching about even worse things, and we lead the nation in murder.

I'll look at the fluid tomorrow. I know I said that yesterday, but after 12 hours of work and running 5 miles, I forgot about it. The techs working on the car are alright. They are GT-R certified, and the service manager has been in the business for 20 years and has a very good reputation. I don't think they are missing anything obvious.

If my driving style is the issue, I want a refund on the "sport" package, and Nissan needs to change their product brochure to reflect that stopping should not ever occur from above 50mph, nor brake pressure exceed 25% capacity.

The first time I wrecked my OEM rotors/pads was a panic slow on the freeway when some idiot tried to run me off the road. Call it 70-40 pretty quick. Then back to freeway speeds. Ever since then...that was the first time I actually "stabbed" the brakes.

Did it again a while back after they fixed them from 40mph trying to sling the phone that fell and dropped forward from under the seat so I could pick it up at the next stop-sign. Yep. You guessed it. Warped again immediately.

Any time you use the brakes at any real capacity, this piece of crap warps them.

roy'sz · 05-26-2013, 07:10 PM

Tq check the caliper bracket. That could cause the rotor to warp via a loose caliper.

Chuck33079 · 05-26-2013, 08:00 PM

One stop should never destroy a set of rotors. I've made plenty of panic stops and used my brakes hard with no issue. There's definitely something wrong with yours, and I'm at a loss as to what it is. You've replaced everything but the calipers, and you'd be able to feel it or hear it if a caliper was frozen. I doubt it's heat related, since you're saying it happened after a single stop. Have YOU gotten under the car and looked around? Are the rotors visibly damaged? Are the pads evenly worn? Is everything torqued down? Something's off in your front end. Lastly, this is a stupid question and I'm not trying to be insulting, but you're not holding the brake pedal down when you're stopped, right?

The rotors look ok to the eye. OEM pads looked glazed after 500 miles after being shaved, have not seen stoptech pads. I typically rock the car on inclines or let it creep on declines, even though I doubt I get it hot enough to matter, its habit. They have replaced so much **** they would have caught poor tq values by now or fixed it inadvertently. This is admittedly my first set of slotted rotors. Could it be that slight front end vibration and steering wheel shimmy/vibrarion under braking is normal with them?

ImportConvert · 05-26-2013, 10:17 PM

I'm actually looking at the brz. If they came out with an STI model, I might try one more import. Great mileage, and allegedly good handling, and I've heard good crap about subaru. The power isn't really something I worry over. Coming from a c6 z06 to the 370z, I have not missed it, but the brz STI would need a bit nicer interior than the regular brz to seal the deal.

ImportConvert · 05-26-2013, 10:19 PM

This brake thing is wearing me thin. Handling is #1 for me, and brakes are a big part of that. My z is a disappointment.

Chuck33079 · 05-26-2013, 10:19 PM

How slight is "slight"? I'm running out of ideas. If it were my car, I'd get it up in the air and check that everything is tight myself. There's no replacement for verifying things yourself.

The slots should be cleaning off any glazing on the pads, so it seems odd to me that they're already glazed. My next wild *** guess would be a wheel balance issue. Maybe if it's just a little off you could be feeling it under braking only? I'm grasping at straws at this point.

Did you have an accident, or am I confusing you with someone else? If so, was the front end involved? Maybe something got tweaked there.

Chuck33079 · 05-26-2013, 10:23 PM

If you try another import, Subaru is a good place to start. Although most imports these days are built here, and it seems like a good chunk of domestics are built in Canada or Mexico.

I feel for you. Recurring issues drive me up the wall. At this point I'd try another dealer simply to rule out another variable.

Yes, a girl hit my car. It warped its first rotors thousands of miles earlier, though. Very badly. The alignment was redone twice and the front rims are new and have been rebalanced. The vibration was bad enough last time to loudly rattle the bracelet on ky Explorer II, and not quite there now, but at its rate of progression, will be in another week or two. It seems to get progressively worse every day. I kindof want to wait until its OMFG!?!? Bad before I take it back in to the dealer to help underscore my irritation.
