Steering wheel vibration when braking at 80 km/h

[528i_tourer]

Well today when driving at near 80 km/h and braking i felt a vibration on steering wheel. Below 60/80 i dont feel anything but at more than 80 these symptom appears everytime i brake.
What can it be ?

Thanks

sounds like your front rotors are warped, how old are they?

Dont really know...i bought these car recently...with 230000 kms and had been on a service changing some stuff like rear brakes/discs

Î brake between 80 and 140 km/h and the steering starts to vibrate then it stops vibrations below 80 km/h

Sounds like a suspension bush to me, or it might be your wheels are out of balance. Try it with your wheels balanced 1st.

front rotors warped. get them checked and turned or time to upgrade.

The same thing happened to my 530i and turn out to be the TIE ROD from the driver side.

My 740IL suffers from the same, when the speed exceeds 80Km/hr I start feel with vibration on the steering wheel and this vibration will increase by stepping on the brake.
I've sent the brake disks to lathe, but still I have the same problem.

if it's not warped rotors then it could be the bushings on the control arms.
I had both problems on mine and new rotors and new control arms with bushings took care of it
