this is what I thought you meant by a heat gun, not a digital thermometer import

It's really strange you're still having issues. So you've now established that it's not the pads or the rotors themselves. The only variables left are the calipers, cooling, the install or your style of driving. Is there any way you can get a temperature reading after some spirited driving? I'm at a loss as far as why this problem keeps popping back up. The only thing made by Nissan in your brakes are the calipers, and I doubt that's the problem. Are there any other dealerships you can take it to in your area?

Yes, actually they are, for 12/12, and mine first began showing problems at 10K miles of street driving. No, I won't be at the same point. I've owned "many" cars (for a 27yo), and I have literally NEVER had these issues. In fact, I was in a Kia Optima for about a month earlier this year, and it didn't develop any issues with its brakes. My car takes about 2-3 weeks to start shuddering pretty bad sometimes after service (for same issue).

I'm glad you lucked into a good 370Z, but if my Z06, WS.6, G20, 1988 GT, 1993 Crown Vic, 1995 Trans Am, and the Kia rental car can all handle my driving, then **** this pussy **** if it can't.

I take 5 corners in 13 miles on the way to work. Exactly how spirited can you get given the above!?

Yes, there is another dealership, but so far this one has been very accommodating and agrees that the problem is BS and should never occur on a street-driven car where the owner is getting 17K+ miles out of the OEM tires and showing even wear on front/rear tires and pads.

Dear god no. We had a misunderstanding. Someone that stupid shouldn't be allowed to make enough money to afford more than a scooter.

Then I don't know what to tell you. Maybe you got a bad one.

You could be suffering from a caliper failure where it is slow in response to pressure and the relief of it. Have you thought of Nissan looking into it? Is it only on one side or are both warped? Im not trying to be prude either but comparing sedan brakes to 4piston brakes is like apples and oranges. 99.9% of sedans have floating calipers in comparison to fixed calipers. When you have a fixed caliper the sensation or warped rotors is more evident or apparent then on a floating caliper. The reason you cant feel it as quickly on a floating caliper is the caliper is able to move and not get any binding from the rotor forcing the caliper inwards or outwards (hope this makes sense).

Also since you brag about your time of 13 minutes (which is cool by any means to brag about times) how much time do you have before you park your car? Is it city driving where you don't have 10 minutes of non brake driving to cool the rotors down? If not that could be the most probable cause in the rotors warping. These cars are designed to take a beating, but HEAT is the most common problem in all aspects:brakes, engine, tires etc.

I'm 28 and have owned 2 mustangs, 2 sentras, 2 ford rangers, 1 Toyota Tacoma (big brake kit) and 1 370z. Only 2 have had 4 piston calipers and my experience with brakes is pretty spot on being that I have glazed rotors and warped them myself too many times to count when I was under 22. Take an honest look at your driving characteristics and maybe there could be probable cause there rather than it being mechanical? Also if you google image search the brembo kit on a mustang it is exactly the same style caliper. Just a fyi all 4,6,and 8 piston brake kits are FIXED calipers just like our Z's.

Hope this info helps.

Your problem most likely has nothing to with the brakes at this point.

Have you checked your steering rack or ball joints/control arms.. I have seen both cause a vibration under braking. Also, they make gauges for caliper pressure to ensure the calipers are working right any dealership/reputable performance shop should have a set of them.

Its a solid rotor as you can imagine its quite the same as the side that is machined except you can't tell its warped in a photo that I am sure I don't have because that was from like 2005. I have another warped rotor on the rear of my car right now from exactly the same problem that warped that one. However, I am not going to machine it down simply for internet rep.. The proof you can warp rotors is clearly shown in that photo if you don't want to believe it then continue to live in ignorance.

I said 13 MILES. Five corners, and a maximum of 7 stops. Most from under 50mph.
Point well taken on the calipers.
No other car I have owned has done this. Maybe 370z owners can retrofit ten year old sentra brake kits, or just get into a real car. I'm going to heckle Nissan until they lemon the car, or I break even and trade up. Or they somehow fix it. Other than that, this is crap. What do you get, like 30 seconds of track time per rotor!? Lmao. This is a family car with two seats.

The problem does go away for a few hundred miles each time the brakes are done.

I understand the 5 corners and 7 stops, but if they are hard stops then that is the root cause. 2ndly if not that then maybe a sticking caliper? one way to tell is if you have a temp gun check the rotor temps when you get done driving it. if you jack the car up and try to rotate the wheels, that is a easy way to diagnose. How is the brake fluid quality?

I'll look at the fluid tomorrow. If the brakes can't take a few 60-30's and 45-0's, then why the hell even call it a sports car. Just call it a pos and don't polish the turd. American cars don't have this issue in my experience. Going back to them as soon as I can.

370z's usually dont have any issues and the brakes are in generally very impressive for a factory brake system. You have an issue with something other then the pads/rotors or the people doing the work.

I dunno, the rest of the car has been decent enough, the brakes have totally ruined it thus far, though. I won't recommend Nissan. I won't ever own another one. I want out of this lemon. Pieces of cheap ****.

Hmmm I drive my Z like I stole it and I don't have any issues. I blame it on you being in crappy Louisiana.

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