Steering Vibrates Whilst Braking

[tcornelio]

Hi All,

I have a 2005 BMW X5 E53.

When applying the brakes and going over 90km/h an hour the steering wheel vibrates vigorously. However if i am going even faster e.g. over 160km/h then the vibration is not as bad which does not really make sense.

Maybe unrelated but when the car is stopped but in the drive position and i apply/release the brakes i can hear a sort of squeak noise coming from the front, sounds like the brake discs.

I do know that the front brake pads where replaced with after market brake pads by the previous owner just before i bought it a month ago.

Could the issue be bad brake pads or do the discs themselves need replacing?

It cannot be the tyres i have just purchased 4 new tyres last week and they have been balanced.

Thanks
