Hey All,



I am experiencing quite a bit of vibration while braking under speeds at approx. 100 kilometres or more. New brake pads and rotors and on the car and also has brand new run flat tires. Vibration in felt in the pedal, steering and front end of the car.



Can anybody help???

I am going to throw out an obvious issue. Perhaps you need to tighten the lug nuts on your tires.
I think that it is a brake problem, but it also sounds like the application of pressure is causing some weird rotation of the front tires.
I am probably wrong, but just a thought.

I once had a similar problem and it turned out to be a faulty wheel bearing...
That was not on an E60 though - I had a 406 at the time.

Lug nuts are tight no issue there but something is very odd and its now starting to drive me crazy going back to dealer tonight to see if SA or tech will come for a drive with me.

Update......ok so the SA drove the car yesterday and says the front rotors are aftermarket and this is what it causing the vibration during baking at higher speeds apparently they cannot handle the braking power of the car. They are suggesting to change them to back to Original Man. rotor to correct the issue.
