Braking and Speed Vibration

excalbr8 · 11-29-2012, 06:16 AM

Hi,

I have a 2002 330 Sport and It vibrates badly when I brake. This gets worse as I get faster. There is no vibration when driving under about 60 but by 80 it is bad, but not through the steering until I brake, then the whole car vibrates. I have replaced the front and back disks (rotors) and the pads, the front lower suspension arms ( with Meyle ones) and the front arm bushes and anti roll bar bushes (sway bar) The latter are both Powerflex. I have also had the wheels balanced.

Currently I dont know whether to start on the rear bushes, wheels or sell the car! Even though it still runs great and has never let me down in the 6 years i have owned it. It has done about 107,000 miles.
I am tearing what little hair I have left out with this, so any suggestions welcomed, Thanks.

What's about the wheel bearings? Have you check them?

I had a similar problem, replacing the rotors and pads solved it.

I have replaced one of the front wheel bearings and sont hear any noise from the others when I jack up the car and turn the wheels, which I would expect if it was them, but it is possible. The rotors and pads was my first thought as well, unfortunately didn't make a difference. I am using EBC green stuff pads, so I suppose they could be the cause.

Thanks
