Vibration when off the gas and off brake - PeachParts Mercedes-Benz Forum

I just did a brake swap on my 190E to the E420 calipers and rotors and noticed an interesting vibration problem with the car.

on the freeway when I was preparing to exit, I let off the gas and noticed a pretty bad vibration coming from the car (not sure where exactly its coming from). I also noticed that the vibration goes away when I apply the brakes as well.

it seems independent of the drivetrain as well because when I put the car in neutral and coast, it vibrates, but once i apply the brakes, vibration goes away.

any idea what is wrong? I plan to check the wheel lugs again, maybe I tightened them incorrectly.

Not familiar with 190 calipers vs a 420 but its obviously related to what you did. Am assuming the 420 are beefier?

Assuming you did everything correctly, maybe the hub/spindle of the 190 is not designed to take the beefiness/weight of the 420 calipers? Just guessing.

Do you know of someone else who did this? Is this why you tried it?

ok it was the wheel, false alarm

torqued everything back down and its all good.
