Why is my car vibrating when braking??

[Miller350z]

So I then went out and did a good bedding in procedure. Started 50mph to 20mph and then 70mph to 30mph. I did at least 30 brake applications and it's still the same. So I'm thinking warped discs. I double checked and fitted them on 11th September and they've done less then 2000 miles. What do people think????

Any advice or opinion would be appreciated.

Thanks

Seems like one of the discs has a manufacturing defect, I bet that's what it is. Are you sure the one disc has this thickness difference and the other not? If so, then I'd say you've probably found your culprit.

Discs aren't warping (read that article), and very, very unlikely that they manufactured duff discs, unless super dooper cheap crappy thingys.

Hi Miller, did you ever get to the bottom of what was causing the brake vibration? I'm in a similar situation, I've just recently brought a 350z and joined this forum. The previous owner had replaced the discs and pads, but I'm getting vibration too.
