The sound of friction from the passenger side brake rotor
Yesterday, I replaced all the brake rotors and pads for my 2014 ML350. After the replacing, tested driving for about 20 minutes. Everything was good except there was some sound of friction from the front passenger side. When I drive faster, the frequency of scratch will become more often. I guess the new rotor scratched the wheel hub as the pictures shown (red part). The rotor was made by ATE from FCP Euro。 Brake pads are Genuine MB. Any guys ever meet this kind of kiss?

Wipe the rotor surface clean with a cloth or paper towel, where it was touching the terribly rusted hub.
Use a thin film of grease on the hub nose where the rotor is piloted.
Confirm the calipers slide freely on the pins.
Use a torque wrench to tighten the wheel bolts.
Thank you.
I will remove the rotor again to check whether there is some touch between the rotor and hub. If so, I will scrub all of the rust off and grind off hub touch part.
I have done for these steps and will redo "Use a thin film of grease on the hub nose where the rotor is piloted.
Today I checked again and found the sounds from the rear right wheel hub. It was a little warped, so I used a screwdriver to pry it back into place and the noise went away.So happy.
I had the sort of problem on my E550 with aftermarket rotors and pads. Tried mercedes pads, still had the noise. My shop said to use mercedes rotors. They were right, rubbing sounds stopped. Just my experience FWIW.

I found it was the problem of my wheel hup. The rotor was no problem because it ATE worked as OEM factory for MB.
