No vibration on driving just braking.

Rotors can also warp if the wheel bolts were torqued incorrectly, to very high values. All bolts should be at around 120Nm.

I used 88 Ft-Lbs to torque my wheel bolts. That should be close to 120Nm, right ?

Nm x .738 = ft/lb

So, 88 is close enough!

Went to dealer this morning, and the tech. was driving my car with me. He confirmed the vibtration and said that it was due to the rust on the pads and rotors.

He told me that the vibration will be diminished by itself over time. He also told me that dealer can replaced the rotors for me but I will get charged. The replacement is not covered under the warranty because it is due to corrosion.

So driver beware .... brake rotors/pads replacement only be covered under warranty if it is worn out under normal use NOT corrosion.

This morning, the vibration is much less than before, but is still there.

I have the same problem sometimes too. Especially when i tried to brake in high speeds. Does this occur only on 530i ?
