(video) Replace the front brake rotor and pad
If the vibration occurred when you brake at high speed, the brake disc is deformed and needs to be replaced; if it squeaking when braking at low speed, it is a problem with the brake pads, so replace it. Also, I replaced the semi metallic brake pad to ceramic brake pad.

Excellent Video as usual.
One thing i would have done though is clean the Hub mating surface with a steel brush before mounting the new brake disc. You surface looked pretty clean but most people are not that lucky and it can make the new disc wobble.

Yes, the wheel hub should be cleaning, I just cleaned at last disc replacing one year ago. This discs are defective, so I have to replace them.

Good video but one thing is not right. You should NEVER hit the wheel like in the video he uses a very big hammer to loosen the rotor from the hun. It is very easy to damage the wheel bearing especially when the rotor is not rotating when hitting it.
I have not looked at this in my car so my question is: The set screw n the hub/wheel-is it threaded to the wheel or the hub? If it is threaded to wheel then a bolt in this hole could perhaps be used to push the wheel out without hammering on it.

There is no any tip about how to gently remove the rotors from the hub on WIS of MB. So I have to spray some WD-40 to soak into the gap between rotor and hub, to loosen adhesion. And then lightly hit the rotor by hammer. I think that hitting on the bearing won't be greater than the impact of driving on the road.
I think😂All of the locking screw and the lug bolts are threaded into the hub, and all of the rotor and the wheel are thru holes, so there is no way to push the rotor out.

Thank you, and your worry is reasonable.
