Vibration when braking need some help!

Thanks again guys... I called Nissan and even though I rather not bring the car there I didn't wanna pay for new rotors already... Anyway found out I have to pay because brakes are only covered for the first year! I will check the rotors and be 100% sure.

you can take them of and go get them turned if you didn't glaze the rotors. You mostlikely got this horrible task accomplished by doing some significant braking and then parking it soon after. If you drive around and you start to really get those brakes heated up, you should try to find a way to drive your car without hitting your brakes for approximatly 5-10 min so that they have a chance to cool down. Try downshifting some more.

Thanks Rusty... Love your build thread btw... cant wait to see more.

43k on stock pads and rotors.....no problems with vibrations here. Like i stated before in previous post, If you are braking hard and parking it immediately then you are effectively attempting to warp your rotor. I did hard braking from over 130 in my Z last thanksgiving week but drove 15-20 min solid without using my brakes and have yet to have any glaze,warp, or vibration issues. Stock pads and stock rotors.

That's good, but he's right. Any OEM brake pad formula (Highest-end cars aside) has a propensity for this because they're pretty much universally 'Material Transfer' pads.

The only cars I've owned that this has happened have been ATX cars where you HAVE to apply brake force much more often than in an MTX.

The worst part is, it can be hidden from you in a used car by having the rotors turned. As soon as you wear them in a little it'll come right back, because it causes a chemical change in the rotor material that goes deeper than the surface. You have to take of a couple tenths of the entire rotor surface to get below it (which may result in taking off several tenths on the high spots), which almost never happens. They just even it up and call it a day.
